NOVA简明教程
NOVA简明教程NOVA是一个高效易用的开源张量框架，主要用于深度学习中的计算图构建和自动微分。
它支持动态图模式和静态图模式，能够自动计算梯度，并且可以在CPU和GPU上运行。
本篇文章将为大家提供一个简明教程，以帮助大家快速入门NOVA。
1.安装首先，我们需要安装NOVA。
可以通过pip命令进行安装：```pip install nova```2.张量的创建与操作在NOVA中，我们可以使用`Tensor`类来创建和操作张量。
下面是一些常见的张量操作示例：```pythonimport nova as nv#创建一个张量x = nv.Tensor([1, 2, 3])print(x)#张量的形状print(x.shape)#张量的维度print(x.ndim)#张量的类型print(x.dtype)#张量相加y = nv.Tensor([4, 5, 6])z=x+yprint(z)#张量的逐元素乘法z=x*yprint(z)#张量的矩阵乘法a = nv.Tensor([[1, 2, 3], [4, 5, 6]])b = nv.Tensor([[7, 8], [9, 10], [11, 12]])c = nv.matmul(a, b)print(c)```3.动态图模式NOVA支持动态图模式，可以像普通的Python程序一样运行和调试代码。
下面是一个使用动态图模式的示例：```pythonimport nova as nvimport numpy as np#创建一个可训练的变量w = nv.Variable(np.array([1, 2, 3], dtype=np.float32))b = nv.Variable(np.array(4, dtype=np.float32))#输入张量x = nv.Tensor(np.array([5, 6, 7], dtype=np.float32))#计算模型输出y = nv.dot(w, x) + b#打印结果print(y)#反向传播计算梯度y.backward#打印梯度print(w.grad)print(b.grad)```4.静态图模式除了动态图模式，NOVA还支持静态图模式，可以在构建计算图之后，通过调用`backward`方法一次性计算所有变量的梯度。

T op wildlife guard latched around the top bushing skirtIntegrated voltage sensor option (6 sensors)The NOVA NX-T recloser is available with integrated voltage sensors for source- and load-side voltage sensing. This is accomplished by using a high-voltage resistor encapsulated within each interrupter module for source-side voltage sensing, and a load-side resistive sensor encapsulated in silicone rubber insulation connected to the recloser’s load-side terminal. The integrated voltage sensors and recloser control system support a voltage-sensing magnitudeaccuracy of ±2% and a phase-degree accuracy of ±1.5° over the full rated ambient temperature range of the recloser and control. The accuracy for this system applies when the following conditions are met:●Voltage range is greater than 50% to 100% of the rated maximum voltage of the recloser●Ratio of load-to-source voltage magnitudes is between 0.5 and 2.0, inclusive●Phase angle difference between load and source voltages is no greater than 30 degreesThe load-side voltage sensor can be installed at the factory, or can be installed in the field as a service kit. When installed, the load-side top terminal is connected to the recloser load-side terminal, and the end of the sensor is securely connected to the recloser tank head. The load-side sensor connections are made within the recloser tankhead and transmitted to the frame’s integrated junction box through a single cable using Eaton’s MIL -DTL -38999 Series IV connector system.A single 37-pin control cable is used to bring source and load voltages to the Form 6 NX-T control, in conjunction with other control cable signals including TRIP and CLOSE, recloser status, and current values. The control cable uses Eaton’s MIL -DTL -38999 Series IV twist-lock cable connector design.Service informationService requirementsThe NOVA NX-T recloser has been designed with aminimum mechanical life of 10,000 operations. The NOVA NX-T recloser requires minimum routine inspection to check for physical damage and verify proper operation.It should not be necessary to access the mechanism of the NOVA NX-T recloser.Frequency of inspectionBecause these reclosers are applied under widely varying operating and climatic conditions, service intervals are best determined by the user based on actual operating experience. However, solid-insulated, vacuum-interrupting reclosers should be inspected every ten years.High-potential withstand testsNOVA NX-T reclosers are carefully tested and adjusted at the factory to operate according to the published data. Each recloser leaves the factory ready for installation, but to ensure there was no damage during transportation, Eaton recommends high potential withstand tests before installation.To verify the dielectric integrity of the recloser, the following tests and equipment are recommended:High-voltage test set – Must be capable of supplying suitable voltages for determining the dielectric withstand capability of the recloser. Sensitive circuit breakers should be included to prevent damage in the event of a flashover.Notee: Test results for NOVA NX-T reclosers equippedwith voltage sensing options may be influenced by the sensing resistor, especially if DC high-potential testing is performed.18NOVA NX-T RecloserInstallatIon and operatIon InstructIons MN280087EN March 201819NOVA NX-T RecloserInstallatIon and operatIon InstructIons MN280087EN March 2018Withstand test resultsThe high-potential withstand tests provide information on the dielectric condition of the recloser and the vacuum integrity of the interrupters.If the recloser passes the closed-contacts tests but fails the open-contacts test, the cause is likely to be in the inter-rupter assembly.If a recloser fails the closed-contacts test, the cause is likely to be a diminished electrical clearance or failed insulation.If the recloser does not pass either the Open or Closed High-Potential Test, contact an authorized service center or your Eaton representative.otee:N Test results for NOVA NX-T reclosers equippedwith voltage sensing options may be influenced by the sensing resistor, especially if DC high-potential testing is performed.Module flashover serviceIf a NOVA NX-T recloser module was exposed to an external flashover, an inspection process is recommended to assure proper operation of the recloser. Should the NOVA NX-T recloser exhibit external flashover attributes (carbon tracking or discoloration), the following procedure is recommended:1. Bypass and remove the recloser from service asdescribed in this manual.2. Confirm the dielectric strength of the recloser byperforming high-potential withstand test. Refer to the High-potential withstand tests section of this manual.3. Inspect the housing and lifting lugs for damage thatmay affect electrical and/or mechanical performance. If there is damage to either the housing or lifting lugs they must be replaced or repaired.4. Inspect module for damage to the terminals. Removeany damaged terminals and replace.5. Inspect module for damage to the module conductorrods (0.63” diameter threaded rods on top and side of module for affixing terminals). If there is damage to the module rods, the module must be replaced. Contact an authorized service center or your Eaton representative.6. Inspect the operating rod for damage. Check themodule surface and major and minor sheds forcracks, holes, and major chips. If damage is present, the module must be replaced. Contact your Eaton representative.7. If no damage is found, clean the module with isopropylalcohol and a scratch-free, nylon scouring pad to remove any carbon deposit.8. Before returning to service confirm electrical operationby opening and closing the recloser with a control. Confirm the dielectric strength of the recloser byperforming a high-potential withstand test. Refer to the High-potential withstand tests section of this manual.TroubleshootingIf the NOVA NX-T recloser does not perform as described in the Recloser operation section of this manual, the follow-ing information may assist in troubleshooting.Unit will not close●Make sure the yellow manual operating handle is completely up (returned to the CLOSED position). ●Check all cables for proper connection.●Check the condition of the battery located in the control cabinet.

1. Remove the cover from the enclosure using a flat screwdriver .Use a 6mm drill bit to open the required cable entry hole.Centurion Systems (Pty) Ltd 14532Mounting surfaceDrill bitCable saddleCable19. Output Configuration18. Non-Volatile Latches (Sticky Latches)Link Learning is the learning process associated with fitting a plastic link over the J1 pin and the common (middle) pin on the receiver in order to learn remote buttons into memory. Learning buttons using this method will also grant buttons master privileges. There are two primary types of erase that pertain to all the receiver variants:• Transmitter Memory Erase • Settings Memory EraseThe procedure to perform the erase operation is documented below:.1. Start with the receiver powered up.2. If a particular channel compartment must be erased (in otherwords, if all the remote buttons associated with a particular channel must be erased), then fit the channel jumpers that select the desired channel.3. If the entire memory must be erased (or the Settings Memory mustIf a button has been demastered, it can be remastered. There are two methods to achieve this, namely:Link Learn Remastering1. To remaster a remote, start by entering Link Learn Mode. Forreference follow steps 1 and 2 in the Link Learning section 2. To remaster buttons associated with a specific channel, fit thechannel jumper links for that channel. With links fitted, only buttons associated with a selected channel can be remastered. All other buttons will register on the receiver , but will not be processed.Bulk DemasteringSince all remotes that are added to a receiver are always added with master privileges, the HELIX offers users a facility whereby certaingroups of remotes, currently learnt into the receiver , can be demastered simultaneously. This is an important feature since having multiple mas-ters might at times be considered a security risk.To bulk demaster remotes, follow the procedure highlighted below:1. Ensure that there is no power on the receiver .Channel settings modify the way a receiver output responds when it is activated. The output can be configured to act as a latching output, a panic output or any combination thereof. A latching output provides the required drive logic for alarm or equivalent output functionality. Every button transaction associated with a latching output will toggle the current output state of the channel.In the case of multichannel receivers, channel settings are set on an output by output basis. To select a particular output, link the relevant output jumpers (channel jumpers). For example: To set output 1, place a link on channel jumper C1 only. To set channel 11 (a SS II device output), place links on channel jumpers C1, C2 and C4 (the binary combination of C1, C2, and C4 that results in 11 - b’1011’).Proceed as per the steps below to set the required output configuration for the specified output.1. Power down the receiver , and link the relevant channel jumpers toconfigure the respective receiver outputs. On multichannel variants, if no channel is specified via the channel jumpers, the system will not enter channel configuration mode.2. Link jumper J2, and power-up the receiver .3. After the firmware version number has flashed on the Status LED, thebuzzer will provide three short beeps to acknowledge the fact that the receiver is powering up in channel configuration mode.It is possible to disable the functionality associated with jumpers J1 and J2. Receivers are often placed in elevated environments to optimise the range of the receiver . Often, little or no attention is paid to securing the receiver . If the receiver unit is not secured it is possible for a perpetrator to access the jumpers on the receiver and learn a remote into the system without the knowledge or consent of the user . the HELIX range includes functionality to disable the jumpers. With a master remote, the jumpers may be re-enabled at any stage.The following procedure documents disabling the jumper interface on the HELIX range of receivers.1. At least one master transmitter must be learned into the receivermemory.2. Press and hold a master button for between 20 and 30 seconds. Thiswill cause the receiver to enter demastering mode; a single beep at 10 seconds must be ignored, and the button can be released upon hearing a long double beep after 20 seconds.3. While in this mode, fit the link between J2 and the middle pin. TheStatus LED will remain on as long as the pins are bridged.4. When jumper J2 is removed, both jumpers will be disabled and nofurther jumper operations may be performed.To re-enable the jumper interface, repeat steps 1 through 4 again.For further information and programming instructions pertaining to the various advanced features found on Helix receivers, please refer to the appropriate sections in the Helix Full Installation Manual, downloadable from our website .This is a special feature on all receiver variants that allows the receiver to restore its output state on power loss. When power is restored, the output will assume the state it last reflected prior to the receiver los -ing power . Normally a receiver that has latched channels will alwayspower-up with the channels unlatched; regardless of the output state of the channel prior to power loss. The sticky latch feature addresses this problem (in applications where it is seen as a problem), and restores the output state of the latch to its state prior to power-loss.system is not in Bulk Demaster Mode. Either because jumper J1 was not linked correctly before power-up, or because there are no buttons learnt into memory (or associated with the channel selected by the channel jumpers).5. To confirm the bulk demastering operation, jumper J1 must beremoved. If the receiver is powered down before the jumper is removed, the bulk demastering operation is not executed. This isuseful if the mode is entered accidently and no buttons must actually be demastered.Autolearn ModeAutolearn functionality allows the receiver to remain in Learn Mode for a maximum period of 7 days, after which it will automatically time-out. This is useful in cases where not all individuals who have been issued with remotes are present in order to learn their remotes into thereceiver’s memory. Multichannel receivers now support the ability to map buttons to channels during the Autolearn process. Power down the receiver prior to commencing the procedure for entering Autolearn Mode.1. Channel compartments configured for Autolearn must be blank.In other words, the entire Transmitter Memory need not be blank to enter Autolearn, only the relevant compartments. As a result, it is possible to enter Autolearn Mode multiple times; so long as the channels configured for the Autolearn session are blank.2. Fit the desired channel links for the channel that is intended for auto-learning. It is possible to omit channel links and enter Autolearn for channel 1, but only if the channel is blank. 3. Fit the link across J1 and power up the receiver . One of two possiblesituations will result:a. The selected channel (set via the channel jumpers) is blank.In this case the system enters the Autolearn Commissioning procedure. The receiver remains in this state while the link on J1 remains fitted. While in the commissioning state, the LED on the receiver remains on. Entry to the commissioning state is also signalled by a long beep from the buzzer . Continue to step 4.b. The selected channel (set via the channel jumpers) is not blank,or no channel has been selected (no channel links fitted). In this case the system enters Bulk Demaster Mode. Refer to the section with the title, Bulk Demastering, for more information on the behaviour of the system in this mode.4. Press a button on a transmitter to establish the button-to-functionality (channel) relationship. The transmitter that is used to establish the relationship is not learned into memory at this initial stage (although a button that is already learnt into memory may be used). It is purely used to establish the relationship between a button and the selected channel. The LED will turn off while a button ispressed. The LED will turn on again and the buzzer will sound briefly when the button is released. This confirms that the button has been successfully received and added to the association table.5. The last button that is pressed for a given channel will dictate thebutton-to-functionality relationship. For example, suppose button 1 is initially pressed and associated with a channel; channel 3 for argument’s sake. If button 2 is pressed subsequently, and it is the last button to be pressed during the channel 3 association process, then button 2 will ultimately be the button associated with channel 3.6. To add another channel to the current Autolearn operation, changethe channel links to the new channel of interest. Remember , onlychannels that are blank can be placed in Autolearn mode. If a channel that is not blank is selected via the channel jumpers, the LED will turn off on button press, but the receiver will not generate a beep when the button is released. This will signal that the channel is not blank and therefore that Autolearn may not be enabled for that channel.7. Repeat steps 4 through 6 to establish button-to-functionalityrelationships for all the (blank) channels of interest.8. Once the association table has been finalised, remove jumper J1.This confirms the mapping and enters Autolearn mode. The buzzer will beep four times to confirm the transition to Autolearn mode. While in Autolearn mode, the LED will remain on while the system is idle. When the correct transmitter button (only buttons registered in the association table are accepted) is pressed, the LED will turn off. When the button is released, the LED will turn3. To remaster buttons without regard for the channel they areassociated with, do not fit any links on the channel jumpers. This will inform the receiver that it must remaster any demastered buttons that are pressed while in this mode.4. With the learn link fitted, press and release a demastered button toremaster it. If a new button (button not learned into the system) is pressed in Link Learn Mode, it will be learned into the system (refer to the previous section, Link Learning for more information).5. The leading edge of the demastered button transaction isacknowledged with a short beep. This beep occurs irrespective of whether the button is mastered or demastered (in fact it will occur irrespective of whether the button is in memory or not).6. While the demastered button is held down, the LED will flash (64milliseconds on/448milliseconds off) to register that the buttontransmission is being received, and that the button is a demastered button. 7. When the demastered button is released, the receiver will completethe remastering operation and remaster the button. A single short beep will signal the end of the operation, confirming to the user that the button has been remastered. The LED will turn on again at the end of the operation.8. When jumper J1 is removed the receiver will exit Link Learn Mode.Master Learn Remastering1. To remaster a remote in this mode, start by entering Master LearnMode. 2. Only buttons that are associated with the channel of the masterbutton that entered Master Learn Mode can be remastered in this mode.3. Press and hold a demastered button for a minimum of 3 seconds toremaster it. If a new button (button not learned into the system) is pressed in Master L earn Mode for more than three seconds, it will be learned into the system (refer to the section, Learning Additional Transmitters for more information).4. This beep occurs irrespective of whether the button is mastered ordemastered.5. While the demastered button is held down within the demasteringwindow (minimum 3 seconds), the LED will flash (64 milliseconds on/448 milliseconds off) to register that the button transmission is being received, and that the button is a demastered button24. 6. Once the demastering period has elapsed (minimum 3 seconds), theLED will turn on and the buzzer will provide a single short beep. This serves as visual and audible confirmation that the receiver has learnt the button being pressed. The LED will turn on again at the end of the operation.7. Once remastered, the system transitions back to Master Learn Mode.Further buttons may be remastered by following steps 3 through 6.8. If no additional buttons are pressed within the 10 seconds MasterLearn Mode period, the receiver will automatically exit learn mode. This exit is signalled by an extended single beep. The Status LED will turn off and resume its responsibilities in normal mode. This beepoccurs irrespective of whether the button is mastered or demastered.C1C2C3C4J1J2C1C2C3C4J1J21. F it the link to J1 with poweron the receiver . On mul -tichannel receivers, fit the links on the channel jumpers to specify the functionality that is required for remotes that are to be learned into the system.If no channel jumpers are linked, the system defaults tolearning to channel 1.2. When jumper J1 is fitted, the LED will turn on as per Master LearnMode.3. Press a new button to learn it into the system.4. If the button is a new button, the LED will switch off while the but -ton remains pressed to confirm that the system has detected that a new transmitter button has been pressed. Once the button is released, a short double-beep will confirm that the button has been learned into memory.5. If the button is a demastered button, the LED will flash while thebutton is held down. Once the button is released, a short single beep will confirm that the button has been successfully remastered.6. Any additional remotes learned into memory are also given masterprivileges. Hence every button added to the receiver in this way automatically becomes a master for functionality with the channel specified by the channel jumpers.7. There is no timeout associated with Link Learning Mode. The re -ceiver will exit this mode once the link bridging jumper is removed from J1.be erased), then do not fit links to any of the channeljumpers.4. Fit a link bridging J2 and the common (middle) pin.5. The LED will flash 10 times to indicate that it is about to enter theerase procedure. The link may be removed at this early stage without the erase operation completing.6. After the LED has flashed 10 times, it will turn on. The proceduremay still be aborted at this late stage by removing power to the receiver .7. Remove the link across jumper J2 and the middle pin to completethe erase operation.8. The LED will switch off once the relevant memory section iserased. The receiver will return to normal operation after the erase operation completes.The property that differentiates the two erase operations is the state of the Transmitter Memory. If the memory is not blank (i.e. buttons are learnt into memory), then the receiver will perform the Transmitter Memory Erase operation. If, on the other hand, the Transmitter Memory is blank, then the Settings Memory Erase operation is performed.2. If the receiver is a multi-channel receiver , place links on the channel jumpers to select the channel that will be bulk demastered. All the buttons associated with this channel will be demastered. If all buttons (i.e. buttons asso -ciated with any channel) must be demastered, leave the channel jumpers unlinked.3. Fit the link across J1 andthe middle pin and power up the receiver . If the channel compartment pertaining to the selected channel is not blank (has a least one button, whether it is mastered or not, associated with the channel), then the receiver will enter Bulk Demaster Mode. If the entire memory is selected for demastering, then at least one button must be learntinto memory (on any channel) to enter Bulk Demaster Mode.4. Press and hold any master button that is learnt into the system forapproximately 3 seconds. The receiver will transition into Channel Configuration Mode. The receiver will proceed to flash in themanner indicated in Table 10 - One short flash and then a 1 second delay. Then two short flashes and a 1 second delay. Then threeshort flashes and a 1 second delay. Finally four short flashes and a 1 second delay. While jumper J2 remains bridged the flashing process repeats itself indefinitely.5. The link on J2 must be removed once the number of flashes on thereceiver matches the number of flashes that will set the required output configuration - refer to the table below.6. Once the output configuration has been set, it is possible to proceedto set the output pulse time. This step may be skipped by either waiting 5 seconds for the receiver to time out, or byremoving power from the board. In either of the two cases, the currently set output pulse time will be maintained.7. To adjust the relay output pulse time, fit the link across jumper J2again. Ensure that this is done before the 5 second timeout period elapses.4. After the firmware version number has flashed on the Status LED, theLED will begin to flash quickly to signal that the receiver has entered Bulk Demaster Mode. If the LED does not flash quickly then the。

Nova Kool公司交直流两用型冰箱安装说明及故障处理手册说明书
安装说明及故障处理手册交直流两用型2005年八月感谢您选用Nova Kool公司的制冷产品。
我们为世界各国提供移动式，高压电力网及节能型的直流电和交直流电两用制冷产品已有20多年了。
每件产品都会经过一系列测试，以保证我们“努力实现所有生产过程的持续改进，调动所有合作伙伴严格控制质量”的宗旨得以实现。
您选用的产品在车间内已经过至少十二个小时的测试，及质量检测、电气试验，以保证产品的品质、可靠性及安全性。
以防您所选用的产品出现任何问题，请妥善保存以下用户保留联。
我们的保修是两年所有部件保修，从终端客户收到货物日算起。
商品型号#商品序列号#购买日期:______________________________安装调试日期:___________________________经销商名称:_________________________________售后服务电话：00-1-604-523-6515分机号为104或在太平洋标准时间早上7:00至下午4:00间发送电子邮件至：********************NKF-04Rev-Aug17-05温度调节:所有Nova Kool制冷产品都配有不同类型的温度调节器，用来感应蒸发器（冷却台）的温度。
将温度调节器的旋钮向右转动（顺时针方向）可以达到最低温度，向左转动（逆时针方向）温度会升高，向左旋直至听到滴答一声时调节器被关闭。
打开冰箱:根据安装指南安装好冰箱后，请接通冰箱电源，将温度调节器拨至3到4之间。
冰箱内降温后，您还可根据个人要求对温度另作调整。
当温度降至一定程度再放入食品。
将温度调节器拨至较高档比如7不会影响冰箱正常的制冷速度。
交直流两用型冰箱在直流电和交流电下制冷速度相同。
除霜&清理:除霜次数取决于冰箱门打开是否频繁，环境温度及湿度如何。
通常当蒸发器四分之一的面积结霜时除霜为好。
除霜时要切断冰箱电源或将温度调节器逆时针拨至OFF位置。
建议打开冰箱门，将毛巾放在冰箱底部吸附过多的霜层。

另外，数据库需要安装在controller节点上。

2.3.1 DHCP网络配置y配置nova.conf中的flag参数：vi /etc/nova/nova.conf参考配置如下：设置好Controller节点后，可直接将nova.conf复制到Compute和Network节点中。
y网桥配置：cd /etc/networkvi interfacesa. Controller节点参考配置如下：b. Compute节点参考配置如下：c. Network节点参考配置如下：修改完成后重新启动相关服务：sudo /etc/init.d/networking restart测试网络：ping 10.50.5.129ping 2.3.2 VLAN网络配置y配置nova.conf中的flag参数：vi /etc/nova/nova.conf--network_manager=work.manager.VlanManager（或者这项缺省即可）其他参数可以参考DHCP进行配置。
注意：--network_size含义发生了变化，在VLAN模式下--network_size指每个工程的可分配的IP数。
y网桥配置：在nova中，compute节点和network节点是需要创建网桥来构建instance所使用的网络的。
在VLAN模式下，nova-network服务和nova-compute服务是会根据mysql 数据库中的数据自动创建网桥。
y配置网络：nova-manage --flagfile=/etc/nova/nova.conf network create 10.1.171.0/24 1 256进入nova数据库，配置新建network的ID等信息#mysql -u#user -p#password>select id, cidr from networks;>exit#mkdir vlan#cd vlan#vi update_networks.sh将下面的内容添加进去：if [ -z $1 ]; thenecho "You need to specify the vlan to modify"fiif [ -z $2 ]; thenecho "You need to specify a network id number (check the DB for the network you want to update)"fiVLAN=$1ID=$2cat > vlan.sql << __EOF_update networks set vlan = '$VLAN' where id = $ID;update networks set bridge = 'br_$VLAN' where id = $ID;update networks set gateway = '10.1.$VLAN.7' where id = $ID;update networks set dhcp_start = '10.1.$VLAN.8' where id = $ID;update fixed_ips set reserved = 1 where address in ('10.1.$VLAN.1','10.1.$ VLAN.2','10.1.$VLAN.3','10.1.$VLAN.4','10.1.$VLAN.5','10.1.$VLAN.6','10.1.$ VLAN.7');__EOF_然后执行这个脚本文件：#bash update_networks.sh2.4 创建工程并配置环境y查看各项服务是否成功启动：nova-manage service listy创建群组并授权：sudo addgroup nova chown -R root:nova /etc/nova chmod 640 /etc/nova/ nova.confy nova运行环境配置：/usr/bin/nova-manage db sync/usr/bin/nova-manage user admin <user_name>创建一个cloud管理员用户/usr/bin/nova-manage project create <project_name> <user_name>创建一个工程/usr/bin/nova-manage network create <project-network> <number-of-networks- inproject> <addresses-in-each-network>参考配置如下：/usr/bin/nova-manage db sync/usr/bin/nova-manage user admin bch此时会产生密钥：export EC2_ACCESS_KEY=6aa51bfd-6bfb-4a94-bf55-3c4bacc4d59a exportEC2_SECRET_KEY=aba78372-8a22-460c-af7e-d6da1ebf2eef/usr/bin/nova-manage project create bchproject bch为工程创建网络(如果之前有的话最好先删除)：/usr/bin/nova-manage network create 172.16.0.0/25 1 128 100注意：（1）这里的网络参数要和nova.conf文件保持一致。
