'LeNet' is not defined
时间: 2023-09-24 08:14:09 浏览: 31
'LeNet' is a deep learning model architecture that was introduced by Yann LeCun in 1998 for handwritten digit recognition. It is a convolutional neural network (CNN) that consists of seven layers: two convolutional layers, two subsampling layers, and three fully connected layers.
If you are encountering the error message 'LeNet' is not defined, it means that you are trying to use the LeNet model in your code but you have not defined it. You need to either import the LeNet model from a deep learning library or define the model architecture yourself in your code.

name 'LeNet' is not defined怎么解决
这个错误通常是因为你的代码中使用了一个未定义的变量名。在这个错误信息中,变量名是'LeNet'。
要解决这个错误,你需要确保你已经正确地定义了'LeNet'变量。如果你使用的是一个已经存在的库或框架,确保你已经正确地导入了它。
例如,在使用PyTorch时,你需要先导入PyTorch并定义LeNet模型,如下所示:
```
import torch.nn as nn
class LeNet(nn.Module):
def __init__(self):
super(LeNet, self).__init__()
self.conv1 = nn.Conv2d(1, 6, 5)
self.pool1 = nn.MaxPool2d(2, 2)
self.conv2 = nn.Conv2d(6, 16, 5)
self.pool2 = nn.MaxPool2d(2, 2)
self.fc1 = nn.Linear(16 * 5 * 5, 120)
self.fc2 = nn.Linear(120, 84)
self.fc3 = nn.Linear(84, 10)
def forward(self, x):
x = self.pool1(F.relu(self.conv1(x)))
x = self.pool2(F.relu(self.conv2(x)))
x = x.view(-1, 16 * 5 * 5)
x = F.relu(self.fc1(x))
x = F.relu(self.fc2(x))
x = self.fc3(x)
return x
model = LeNet()
```

yzm is not defined
根据提供的引用内容,"yzm is not defined"是一个程序错误,提示变量或函数名"yzm"未定义。这意味着在程序中使用了变量或函数"yzm",但在该位置之前没有定义它。
以下是一个示例代码,演示了"yzm is not defined"错误的情况:
```python
def calculate_sum():
result = yzm + 10
return result
print(calculate_sum())
```
在上述代码中,我们尝试使用变量"yzm"进行计算,但是在该位置之前没有定义"yzm",因此会引发"yzm is not defined"错误。
为了解决这个错误,我们需要确保在使用变量或函数之前先进行定义或声明。例如,我们可以在代码中添加以下行来定义"yzm"变量:
```python
yzm = 5
```
这样就可以避免"yzm is not defined"错误。
