数据加载模块中的迭代错误＆＃x27; numpy＆＃x27;没有属性＆＃x27; Expand_dim＆＃x27;
我想迭代扔火车负载，但我遇到了这个问题，在此错误中有任何帮助。
for imgs, mask in trainloader:
print(imags.shape)
print(masks.shape)
break
AttributeError Traceback (most recent call last)
<ipython-input-31-22799795e016> in <module>()
----> 1 for imgs, mask in trainloader:
2 print(imags.shape)
3 print(masks.shape)
4 break
5 frames
/usr/local/lib/python3.7/dist-packages/numpy/__init__.py in __getattr__(attr)
312
313 raise AttributeError("module {!r} has no attribute "
--> 314 "{!r}".format(__name__, attr))
315
316 def __dir__():
AttributeError: module 'numpy' has no attribute 'expand_dim'
I want to iterate throw the trainloader but I face this problem, Any help in this error .

看来您正试图覆盖Pytorch中的数据加载类，并实例化了一个名为“ Trainloader”的数据。当您覆盖DataLoader类时，您会制作错字。您有expand_dim，单数，应该是expand_dims，复数。
返回到班级定义，即火车加载程序基于并更新该行以说“ Expand_dims”
It looks like you were trying to override the Dataloader class in PyTorch and instantiated one called "trainloader." When you overrode the Dataloader class you made a typo. You have expand_dim, singular, where it should be expand_dims, plural.
Go back to the class definition that trainloader is based on and update the line to say "expand_dims"
