NameError: name 'num_epochs' is not defined,该如何定义

这个错误通常是因为在使用变量 `num_epochs` 之前没有定义该变量。你需要确保在使用 `num_epochs` 变量之前先进行定义。例如:
```
num_epochs = 10
for epoch in range(num_epochs):
# 在此处使用 num_epochs 变量
...
```
如果你已经定义了变量 `num_epochs` 但仍然出现该错误,那么可能是因为你在变量定义之前尝试使用该变量导致的错误。在 Python 中,变量的定义必须在使用之前。

NameError: name 'num_epochs' is not defined
This error message means that the variable `num_epochs` has not been defined in your code. You need to define it before using it in your code. You can define it like this:
```
num_epochs = 10
```
Replace 10 with the desired number of epochs.
NameError: name 'training_epochs' is not defined
This error occurs when you try to access the variable 'training_epochs' in your code, but it has not been defined or declared before. To fix this error, you need to declare or define the variable 'training_epochs' before using it in your code.
For example, you can define 'training_epochs' as follows:
training_epochs = 10
This assigns the value 10 to the variable 'training_epochs'. You can then use this variable in your code without getting the NameError.
