torch里model()用法
torch里model()用法PyTorch是一个流行的深度学习框架，它提供了许多方便的功能和工具，使开发人员能够更轻松地构建和训练神经网络。
在PyTorch 中，model()函数是一个重要的工具，用于创建和加载模型。
本文将介绍torch中model()的用法，包括其基本概念、创建模型、加载模型等。
一、model()的基本概念在PyTorch中，model()函数用于创建和加载模型。
它接受一个模型类或一个已经定义好的模型实例作为参数，并返回一个模型对象。
通过使用model()函数，开发人员可以轻松地创建和加载各种类型的神经网络模型，包括卷积神经网络（CNN）、循环神经网络（RNN）等。
二、创建模型要使用model()函数创建模型，需要先定义模型类。
模型类通常继承自torch.nn.Module，并实现其子类中的方法。
这些方法包括前向传播（forward()）和其他必要的操作。
下面是一个简单的示例，展示如何使用model()函数创建一个简单的全连接神经网络：```pythonimport torch.nn as nnclass SimpleModel(nn.Module):def __init__(self, input_size, hidden_size,output_size):super(SimpleModel, self).__init__()self.fc1 = nn.Linear(input_size, hidden_size)self.relu = nn.ReLU()self.fc2 = nn.Linear(hidden_size, output_size)def forward(self, x):x = self.fc1(x)x = self.relu(x)x = self.fc2(x)return x```要使用上述模型类创建一个模型对象，可以使用model()函数：```pythonmodel = torch.nn.model(SimpleModel, input_size=784, hidden_size=500, output_size=10)```这将创建一个SimpleModel类的实例，并将其传递给model()函数。
model在python中的用法
model在python中的用法在Python中，"model"通常用于指代机器学习中的模型。
模型是指通过训练数据学习到的一个函数，用于解决特定的问题或预测特定的结果。
以下是在Python中使用模型的一些常见操作和用法：1. 导入模型：首先需要导入相应的机器学习库，如scikit-learn （sklearn）或TensorFlow。
例如，使用以下语句导入线性回归模型：```pythonfrom sklearn.linear_model import LinearRegression```2. 实例化模型：在导入模型后，需要实例化一个具体的模型对象。
例如，使用以下语句创建一个线性回归模型的实例：```pythonmodel = LinearRegression()```3. 训练模型：使用训练数据对模型进行训练。
通常，需要将数据拆分为特征和目标变量，并使用模型的训练方法对数据进行训练。
例如，使用以下语句训练线性回归模型：```pythonmodel.fit(X_train, y_train)```4. 预测结果：使用训练好的模型对新的数据进行预测。
通常，需要提取新数据的特征并使用模型的预测方法进行预测。
例如，使用以下语句对新数据进行预测：```pythony_pred = model.predict(X_test)```5. 评估模型性能：使用评估指标（如均方误差、准确率等）来评估模型的性能。
例如，使用以下语句计算线性回归模型的均方误差：```pythonfrom sklearn.metrics import mean_squared_errormse = mean_squared_error(y_test, y_pred)```6. 调整模型参数：模型中通常有一些可调整的参数，可以通过调整这些参数来改进模型的性能。
例如，在线性回归模型中，可以通过设置正则化参数来控制模型的复杂度。

MIT还提供了丰富的样式和布局选项，使开发者可以轻松地设计出符合自己需求的界面。
除了创建界面模型，MIT还提供了一些功能强大的工具，帮助开发者管理和调试界面。
开发者可以使用MIT的调试器来查看界面的运行时状态，并对界面进行实时调试。
他们还可以使用MIT的性能分析器来分析界面的性能瓶颈，并优化界面的运行效率。
在MIT中，界面模型被表示为一个抽象的层次结构，其中每个组件都是一个节点。
开发者可以对这些节点进行操作，比如添加、删除和移动节点，以及修改节点的属性和行为。
他们还可以使用MIT的数据绑定功能将界面与用户数据进行关联，实现数据驱动的界面设计。
第二篇示例：Model Interface Toolkit是一款强大的模型接口工具包，通过使用这个工具包，用户可以轻松地创建和管理模型接口。
本文将介绍Model Interface Toolkit的用法，帮助用户更好地利用这个工具包。
一、安装及配置用户需要下载Model Interface Toolkit并安装在自己的工作环境中。
安装完成后，用户需要对工具包进行配置，包括设置模型接口的名称、描述、输入参数和输出参数等。

Keys to Model Test OnePart I WritingSample:On Saving FoodAs we can see from the picture, a big tall man is throwing away leftovers which are quite a lot and seem delicious, while in the dustbin a skinny little man keeps his mouth wide open, eagerly waiting for something to eat. The picture implicitly raises the question of wasting food, which has been a major issue world wide.Food waste means wasting money as well as wasting precious resources. When food is thrown away, it becomes rubbish which can be harmful to the environment and people’s health. And it should also be noticed that there are millions of people suffering from hunger all over the world. Therefore, it’s shameful to waste food.For all of us, it’s meaningful to join in the “Clean Your Plate Campaign”, which helps us realize how difficult it is for a grain of rice to come on our plate and how important it is to save food. It’s wise to order a proper amount of food when dining out. If there’re leftovers, it’s better to take them home. To save food, we should start with ourselves and start from now.Part II Listening ComprehensionSection A1. A2. B3. D4. A5. C6. A7. C8. C9. A 10. B 11.D 12.A 13. D 14. B 15. CSection B16. D 17.A 18.

In the Tang Dynasty, lanterns got connected with Buddhism, since when lighting lanterns has become a part of official activities to celebrate the Lantern Festival. Colored lanternsof different regions have their own distinctive styles and lanterns of different shapes also convey different messages. During the festival, riddles are written on some lanterns. To guess those riddles on lanterns is a traditional entertainment popular among people. Because of the festive atmosphere they bring, lanterns, especially the red ones, are also used in other festivals for decoration.Keys to Model Test TwoPart I WritingSample:Attend Your Classes RegularlyNowadays, it is very common that some university students are late for or even absent from classes. And some students slip out of classrooms before the class is over. Class attendance has become a thorny problem to both the students and teachers.As to the reason for that, both the students and the teachers have fault of their own. Compared with middle school students, college students have relatively more “freedom”. If they are not strict with themselves, they probably will oversleep in the morning, surf on the Internet or find other activities to entertain themselves during class hours. On the other hand, some teachers still conduct classes in the old fashioned way, which makes their classes so boring that many students fall asleep.Despite all those excuses for not attending classes regularly, I firmly believe that it is crucial for students to attend their classes regularly, for it ensures students to catch up with teachers in their learning. What’s more, attending classes regularly will help to form a good habit of punctuality, which is imperative for students in their future jobs. Therefore, university students should attend classes regularly.Part II Listening ComprehensionSection A1. A2.C3. D4. A5. B6. B7. D8. D9. C 10. A 11. D 12. B 13. A 14. A 15. DSection B16. B 17. C 18.

According to researches, the Chinese have had the custom of celebrating the harvest during the autumn full moon since the Shang Dynasty. The celebration as a festival started to gain popularity during the early Tang Dynasty. Gradually, the Mid-Autumn Festival has become a day for family reunion, as Thanksgiving Day in the United States. In the evening, people hang up lanterns, sit around a table to have dinner and moon cakes when looking at the bright moon. The festival was listed as an “intangible cultural heritage” of China in 2006 and was made a Chinese public holiday in 2008.Keys to Model Test ThreePart I WritingSample:Employment Problem of College GraduatesAs we can see from the chart, the contract signing rate of both undergraduates and postgraduates in 2013 is obviously lower than that in 2012. The figures in the chart indicate that Chinese graduates are facing a tough problem of finding jobs in the fierce competition.The most direct reason of this problem is the increasing enrollment of college students. However, the job market gets shrinking, as a result of which a large number of students cannot get hired. At the same time, college students should also be held responsible for this, for they either have unrealistic expectations of jobs or they cannot meet the job requirements.As far as I’m concerned, pressure is not only an obstacle but also a motivity. As college students, we must work harder than ever before to keep our competitiveness. Meanwhile, the Government should try to promote employment of college graduates by working out preferential policies. Only through the combined efforts, can this problem be relieved and solved eventually.Part II Listening ComprehensionSection A2. A 2.B3. D4. A5. B6. C7. A8. D9. C 10. A 11. C 12. D13. D 14. D 15.

It was developed during the early Ming Dynasty and dominated Chinese theatre in the Ming and the Qing Dynasty. By far, it has had a history of more than 600 years. Many Chinese traditional operas, including Beijing opera, have been developed on the basis of Kunqu, for which it is reputed as “the mother of Chinese opera”. Kunqu was listed as “one of the Masterpieces of the Oral and Intangible Heritage of Humanity” by UNESCO in 2001. China has become one of the 19 countries to get such a special honor for the first time.Keys to Model Test FourPart I WritingSample:On TV Dating ShowsTV dating shows are getting increasingly popular among China’s national and local TV programs nowadays. The top-rated TV dating show —“If You Are the One” has attracted thousands of people to participate, and many more to watch.It’s easy to understand their popularity, for there is an increasing number of single men and women at marriageable age who are too busy to find their soul mates. What’s more, we cannot deny that these programs bring great entertainment and relaxation to the viewers. In contrast, some people are strongly opposed to them, arguing that the participants are not pursuing love but fame and that the programs promote some incorrect social and love values such as money-worship.From my point of view, such TV shows are just for entertainment and should not be confused with real life and the quest for marriage. But it should also be noted that those shows do reflect some realities in the fast-changing Chinese society. What we need to do is to face up to them instead of holding those shows responsible.Part II Listening ComprehensionSection A1. B2.C3. C4. B5. B6. D7. A8. D9. A 10. B 11. C 12. C 13. A 14. D 15.

They claim that the living conditions on campus are unbearable while living off campus can bring them more convenience and freedom. They can do whatever they want in the house without disturbing others, such as cooking, playing games, watching movies.But others argue that students should be banned from living off campus, as it has many obvious disadvantages. First of all, it may be not safe for a student to live off campus without the supervision or help from faculty members. Secondly, if the students have no self-discipline, they may addict to computer games, or even gambling. Last but not least, compared with living on campus, it should be more expensive to rent an apartment outside.I tend to believe that it’s appropriate to simply ban students from living off campus, because college students, as young adults, should have their rights to choose after all. Universities need be more flexible about the administration of dorms and try to upgrade the overall conditions at the same time.Part II Listening ComprehensionSection A1. D2.B3. C4. D5. A6. B7. A8.

For more than two thousand years, The Analects and Confucianism have had a profound impact on Chinese people and Chinese culture. The core concept of Confucianism “benevolence” is still mainstream values accepted by most people in today’s China.Keys to Model Test SevenPart I WritingSample:Personal Information LeakageStepping into the information age, we are enjoying the convenience brought by information technology. But at the same time we get more worried about the security of our privacy than ever before, since it’s not very difficult for a hacker to invade our computers, steal our files and information and then publicize them without being noticed at all.The danger of personal information leakage is obvious. Once our information is leaked, we will be continuously bombarded by anonymous messages or phone calls via mobile phones and other communication channels for private tutoring, apartment sales, insurance and so on. To make it worse, if our confidential information was made known to criminals, we might have major purchases made on our credit card, money withdrawn from our bank accounts, and even huge loans taken out in our name.So how can we protect our personal information? Some virus-killing software can protect us from being invaded. However, the best way is thinking before acting. For example, avoid filling out forms requiring private information for free trials or other promotions.Part II Listening ComprehensionSection A1. C2.C3. D4. B5. A6. B7.C8. C9. D 10. B 11. C 12. D 13.

This trend is expected to further boost the prospects of young people inthe country.

The talent shortage has made urban planning and architecture one of the most high-paying majors for university graduates.Keys to Model Test EightPart I WritingSample:Should May Day Holiday Be Resumed to Seven Days?The week-long May Day Holiday was shortened to three days in 2007 so as to ease the burden of overcrowded tourist hotspots and add three traditional Chinese festivals like the Tomb-Sweeping Festival, Dragon Boat Festival and Mid-Autumn Festival.However, some people are appealing to the Government for resuming the seven-day May Day Holiday. They claim that the significance of May Day is not only paying tribute to thousands of diligent workers, but also providing them an opportunity to get refreshed and get ready to welcome and embrace the coming work day with vibrancy and vigor. In that case, a three-day off, which is just one day more than normal weekend, would not make any difference to these people. Apart from that, the golden week could help boost the tourism industry as well as domestic consumption.Personally, I prefer to resume the May Day golden week, not only because it falls in the best season for traveling but also because it will be an effective measure to boost domestic demand, to increase employment and to revive tourism and other related industries.Part II Listening ComprehensionSection A1.B2.D3.

torch里model()用法
torch里model()用法在PyTorch深度学习框架中，`model()`是一个用于定义和构建神经网络模型的方法。
该方法可以用多种方式来使用，以适应不同的模型结构和需求。
本文将介绍`model()`方法的基本用法，并提供一些示例以帮助读者更好地理解和应用。
一、`model()`方法的基本用法在PyTorch中，我们可以通过继承`nn.Module`类来定义自己的神经网络模型。
在定义模型结构时，我们需要实现`__init__()`和`forward()`两个函数。
其中，`__init__()`函数用于初始化模型的结构和参数，`forward()`函数用于定义模型的前向传播过程。
在使用`model()`方法时，我们首先需要创建一个模型对象，如`model = MyModel()`，其中`MyModel`是我们定义的模型类。
然后，我们可以调用`model()`来完成模型的前向传播计算。
具体使用方法如下所示：```pythonimport torchimport torch.nn as nn# 定义模型类class MyModel(nn.Module):def __init__(self):super(MyModel, self).__init__()# 定义模型的结构和参数self.conv1 = nn.Conv2d(3, 16, kernel_size=3, stride=1, padding=1) self.relu = nn.ReLU()self.conv2 = nn.Conv2d(16, 32, kernel_size=3, stride=1, padding=1) self.fc = nn.Linear(32*8*8, 10)def forward(self, x):# 定义模型的前向传播计算x = self.conv1(x)x = self.relu(x)x = self.conv2(x)x = self.relu(x)x = x.view(x.size(0), -1)x = self.fc(x)return x# 创建模型对象model = MyModel()# 构建输入数据inputs = torch.randn(1, 3, 32, 32)# 完成前向传播计算outputs = model(inputs)```上述示例中，我们首先导入了`torch`和`torch.nn`模块，并定义了一个名为`MyModel`的模型类，该类继承自`nn.Module`类。

tess模块中英文对照
tess模块中英文对照Tess模块是一个强大的光学字符识别（OCR）引擎，它可以将图像中的文字转换为可编辑的文本。
无论是从印刷品、手写字迹还是其他形式的文字，Tess模块都能够准确地识别并提取出来。
本文将介绍Tess模块中一些常用的功能和对应的英文表达。
首先，我们来看一下Tess模块的基本用法。
要使用Tess模块，首先需要安装它并导入相关的库。
在Python中，可以使用以下代码来安装Tess模块：```pip install pytesseract```安装完成后，可以使用以下代码导入Tess模块：```import pytesseract```接下来，我们可以使用Tess模块中的`image_to_string`函数来识别图像中的文字。
该函数的用法如下：```text = pytesseract.image_to_string(image)```其中，`image`是待识别的图像，可以是一个文件路径或者一个图像对象。
`text`是识别出的文本结果。
除了基本的文字识别功能，Tess模块还提供了一些其他的功能。
例如，我们可以使用`image_to_boxes`函数来获取文字的边界框信息。
该函数的用法如下：```boxes = pytesseract.image_to_boxes(image)````boxes`是一个包含边界框信息的字符串，每一行表示一个边界框，包括文字的位置和大小。
此外，Tess模块还支持对多语言的文字进行识别。
我们可以使用`image_to_string`函数的`lang`参数来指定要识别的语言。
例如，要识别中文文本，可以使用以下代码：```text = pytesseract.image_to_string(image, lang='chi_sim')```其中，`chi_sim`是中文简体的语言代码。
Tess模块还支持其他语言，可以在官方文档中找到相应的语言代码。
unnittest单元测试
unnittest单元测试TestCase 的⼏个特殊⽅法：setUp():测试⽅法之前运⾏，测试前的初始化；tearDown():测试结束后运⾏，测试后的清理⼯作；setUpClass():所以测试⽅法运⾏前运⾏，单元测试的前期准备，必须使⽤@classmethod 装饰器进⾏修饰，setup()之前运⾏。
整个测试只执⾏⼀次。
tearDownClass():所以测试⽅法执⾏结束后运⾏，单元测试的清理⼯作，必须使⽤@classmethod 装饰器进⾏修饰，tearDown()之后运⾏，整个测试只执⾏⼀次。
1.加上测试集合可以批量运⾏同⼀个⽂件.py下的多个测试⽤例： Testsuitif__name__ == '__main__' :testCase1 = unittest.TestLoad().loadTestsFromTestCase(测试类名字1)testCase2 = unittest.TestLoad().loadTestsFromTestCase(测试类名字2)suit = unittest.Testsuit([testCase1,testCase2 ])unittest.TextTestRunner(verbosity=2).run(suit)备注：verbosity<=0;输出的结果不提⽰执⾏成功的⽤例数⽬；verbosity =1,输出结果仅仅以点（.）表⽰执⾏成功的⽤例数⽬；verbosity >=2,输出每个⽤例的执⾏的详细信息；TestRunner.run() 返回⼀个TestResult实⼒对象，其存放着所有测试⽤例的执⾏过程的信息，可以通过dir()⽅法查看。
.TextTestRunner.run() 以⽂本的⽅式2. 按照特定的顺序执⾏测试⽤例unittest.main()是以所有⽅法名的字符串ASCII排序执⾏，可以通过把测试⽤例添加到测试容器⾥执⾏；if __name__ = '__main__'suit =unittest.TestSuit()suit .addTest(类名("⽅法"))suit .addTest(Mytest("test_add"))suit .addTest(Mytest("test_div"))runner= unittest.TextTestRunner()runner.run(suit)3.忽略莫个测试⽅法 @unittest.skip()在测试⽅法前之前执⾏@unittest.skip(“Skipng”)⽆条件的忽略@unittest.skip(A>8，"条件不满⾜")：如果A >8，则忽略；4.命令⾏模式执⾏测试⽤例python -m unittest test_model1 test_model2python -m unittest test_model.Testclasspython -m unittest test_model.Testclass.test_method5.批量执⾏测试模块程序⽂件执⾏：if __name__ = '__main__'testsuit= unittest.TestLoad().discover('.') #加载当前⽬录下的有效的测试模块，“.”表⽰当前的⽬录；⽂件名字以test 开头unittest.TextTestRunner(verbosity=2).run(testsuit)命令⾏执⾏：python -m unittest discover #⽬录需要切换到存放脚本的⽬录下；discover 的⼀些参数：-v :输出详细的信息；-s:发现脚本的⽬录；-p:匹配莫个测试⽂件：python -m unittest discover -p "test * .py"-t:⼯程的跟⽬录下的搜索可以执⾏的测试脚本：例如：python -m unittest discover -t D:\wew\ewe6.使⽤HTML TestRunner ⽣成HTML的测试报告filename="d:\\ly.html"fp =file(filename,'wb')runner = HTML TestRunner .HTML TestRunner (stream=fp,title='Report title',description =‘Report_description’) runner.run(suit)。

以下是关于BaseModel用法的详细解释。
首先，要使用BaseModel，需要从`torch.nn`或`pytorch_lightning`库中导入它。
导入的方式如下：```pythonfrom torch import nnfrom pytorch_lightning.core import LightningModule```BaseModel有一些常用的方法，包括：1. `__init__(`: 用于初始化模型的参数和层。
可以在其中定义模型的结构和设置需要的超参数。
2. `forward(`: 这是一个模型的前向传播方法。
在这个方法中，定义了数据从输入到输出的整个流程。
需要在这个方法中描述模型的结构。
3. `configure_optimizers(`: 该方法用于配置优化器。
在这个方法中，可以设置模型的优化算法、学习率和其他超参数。
4. `training_step(`: 该方法用于定义训练过程的一步。
在这个方法中，可以实现前向传播、计算损失函数、反向传播等操作，并返回相应的训练结果。
5. `validation_step(`: 该方法用于定义验证过程的一步。
在这个方法中，可以实现前向传播、计算损失函数或其他验证指标，并返回相应的验证结果。
6. `test_step(`: 该方法用于定义测试过程的一步。
在这个方法中，可以实现前向传播、计算损失函数或其他测试指标，并返回相应的测试结果。
此外，BaseModel还提供了一些常用的属性1. `hparams`: 模型的超参数。
这是一个与模型关联的字典，其中可以存储和访问模型的超参数。
2. `model`: 输出模型的当前状态，可以使用该属性访问模型的参数。
3. `current_epoch`: 模型当前的训练轮数。
Model Test 6 参考答案
Model Test 参考答案Part I WritingPrecious WaterNo one doubts the importance of water. Human beings live on water, animals live on water, plants live on water and all living things live on water. You can’t imagine what would happen if there were no water in the world!China is one of the countries in the world that are badly short of water. Water problem has become more acute in recent years with the increase of water consumption and pollution. In big cities, the water problem has become even worse. With the growth of population, more and more water is needed. With the development of the industry, a large quantity of water has been and is being polluted. Water pollution is the most serious problem that China is facing. It has spread to rivers, lakes, and even the oceans.In order to survive, man has to be wise enough to treasure water and try to prevent it from being polluted. Man should also know that all resources in the world are limited, including water. Make good use of them, otherwise, man will be punished by nature. To treasure water is to treasure life; to protect our environment is to protect ourselves.Part II Reading Comprehension(Skimming and Scanning)1. A 细节题。
models在python中的用法
models在python中的用法一、简介models在python中通常指的是模型或模拟，用于描述和模拟现实世界中的现象或过程。
python是一种流行的编程语言，具有广泛的应用领域，因此，models在python中的用法也十分广泛。
二、models的分类python中的models可以按照不同的分类方式进行分类。
根据模拟对象的不同，models可以分为物理模型、化学模型、经济模型、人口模型、交通模型等。
根据模拟方法的不同，models可以分为数值模型、仿真模型、统计模型等。
三、models的用法在python中，可以使用多种库和工具来实现和运行models。
常见的库包括numpy、scipy、matplotlib、pandas等。
这些库提供了各种数学运算、数据可视化、数据处理等功能，可以方便地实现models 的建模、求解和验证。
1. 安装库：首先，需要安装所需的库。
可以通过pip命令在命令行中安装，例如“pip install numpy”。
2. 编写代码：根据需要，编写代码来实现模型的建模和求解。
通常需要定义模型的数学表达式、输入输出、边界条件等。
3. 运行模型：将代码保存为python文件，然后运行即可。
可以使用python解释器或集成开发环境（IDE）来运行代码。
4. 结果分析：运行模型后，可以查看结果并进行分析。
可以使用matplotlib等工具将结果可视化，以便更好地理解模型的输出。
四、注意事项在使用models时，需要注意以下几点：1. 理解模型原理：在建模之前，需要充分理解模型的原理和数学表达式，以便正确实现和验证模型。
2. 数据处理：在建模过程中，需要处理各种数据，包括输入数据、输出数据、边界条件等。
需要确保数据的准确性和可靠性。
3. 模型验证：在运行模型之前，需要进行模型验证，以确保模型的正确性和有效性。
4. 适应场景：不同的模型适用于不同的场景，需要根据具体的应用场景选择合适的模型。
djangoModel层常用验证器及自定义验证器详解
djangoModel层常⽤验证器及⾃定义验证器详解在Django中，对数据进⾏校验有两种⽅式：⼀种是通过Form校验，⼀种是通过Model校验。
在此，我对Model中的校验⽅法做下记录。
⽰例之前补充以下⼏点：1、Django数据校验⽅式分为以下三步：Model.clean_fields() 验证字段基本规则⽐如长度格式等；Model.clean() 可⾃定义验证条件和报错信息；Model.validate_unique() 为验证添加的唯⼀性约束。
2、此三步验证通过调⽤full_claen(exclude=None, validate_unique=True)来依次执⾏。
exclude：可以⽤来指定不需要执⾏校验的field。
ModelForm也利⽤这个参数来将field排除。
validate_unique：⽤来指定是否需要执⾏Model.validate_unique()。
3、⽽full_clean()⼜是通过调⽤is_valid()⽅法来执⾏。
4、save()执⾏的时候是不会⾃动调⽤full_clean()来进⾏校验的。
校验应该在save()执⾏之前完成，你可以先在form进⾏校验，也可以在model中进⾏校验。
但是，你必须确保通过这两个校验之后的数据是绝对没有问题的“⼲净”数据，然后再调⽤save()⽅法将数据存储⼊库。
5、校验中的错误处理我们使⽤ValidationError来在Model.clean中抛出错误，这个错误信息将会存储在以NON_FIELD_ERRORS为key的字典中。
这个key是⽤来存储对于整个model中的错误信息的。
如何获取校验的错误信息：from django.core.exceptions import ValidationError, NON_FIELD_ERRORStry:article.full_clean()except ValidationError as e:non_field_errors = e.message_dict[NON_FIELD_ERRORS]如何指定对于某个特定的field的校验错误信息：class Article(models.Model):...def clean(self):if self.status == 'draft' and self.pub_date is not None:# raise ValidationError({'pub_date': _('Draft entries may not have a publication date.')})raise ValidationError({'pub_date': 'Draft entries may not have a publication date.'})...如何指定多个field的校验错误信息：class Article(models.Model):...def clean(self):if self.status == 'draft' and self.pub_date is not None:raise ValidationError({'pub_date': 'Draft entries may not have a publication date.','creator': 'Creator can't be null'})...如何指定全局性校验错误信息：class Article(models.Model):...def clean(self):if self.status == 'draft' and self.pub_date is not None:raise ValidationError('Draft entries may not have a publication date.')...进⼊正题：⼀、如何使⽤验证器：在验证某个字段的时候，在模型或者⾃定义form表单中传递⼀个 validators 参数⽤来指定验证器，进⼀步对数据进⾏过滤。
