NameError: name '_mask' is not defined
时间: 2023-09-27 21:12:21 浏览: 422
This error occurs when a variable or function called `_mask` is referred to in the code, but it has not been defined or declared before.
To solve this error, you need to make sure that the variable or function `_mask` is defined or declared before it is used in the code. This can be done by initializing the variable or defining the function before it is called.

out_with_attention = attention_layer(out, attn_mask) NameError: name 'attn_mask' is not defined
对不起,看起来我在上面的代码中引用了`attn_mask`,但实际上它尚未定义。在将S2注意力加入`TextCNN`时,`attn_mask`通常来自BERT模型的输入,它是用于处理序列填充部分的注意力掩码。以下是更新后的代码段,包括对`attn_mask`的定义:
```python
class TextCNNWithS2Attention(nn.Module):
def __init__(self):
super().__init__()
...
self.s2_attention_layer = S2AttentionLayer(hidden_size, num_heads=self.bert.config.num_attention_heads)
def forward(self, input_ids, attention_mask):
encoded_outputs = self.bert(input_ids=input_ids, attention_mask=attention_mask)[0] # 获取BERT编码结果
out = encoded_outputs.unsqueeze(1) # 将维度从B x T x H扩展到B x 1 x T x H
# 其他部分保持不变
...
# 添加S2注意力层
out_with_attention = self.s2_attention_layer(out, attention_mask=attention_mask) # 使用输入的attention_mask
# 接着连接到线性层
final_output = torch.cat((out_with_attention, out), dim=-1)
return self.linear(final_output)
```
这里假设`input_ids`和`attention_mask`是`forward`函数的输入,其中`attention_mask`是BERT需要的掩码信息。如果在实际应用中这两个变量有不同的名称,请相应地替换它们。
NameError: in user code: File "<ipython-input-66-6d273dc751c7>", line 4, in load_image_train * mask = readjpg_label(mask_path) # 获取路径 NameError: name 'readjpg_label' is not defined
这个错误说明在代码中使用了一个未定义的函数`readjpg_label`。请确保在调用`readjpg_label`函数之前已经定义了该函数。检查一下代码中是否有定义`readjpg_label`函数的部分,或者确认该函数的定义是否在正确的位置。如果函数定义在其他文件中,还需要确保已经正确导入该文件。
