ai_course's Issues

关于手写体识别,下载数据集设置参数后出现如下异常

File "E:/研究生学习/AI_course-master/classify_pytorch/train_mnist.py", line 56, in train
for batch, (batch_x, batch_y) in enumerate(train_loader):
TypeError: pic should be PIL Image or ndarray. Got <class 'NoneType'>

具体为这一行出现异常,batch变量似乎不符合要求
for batch, (batch_x, batch_y) in enumerate(train_loader):
应该numpy格式或者是PIL image格式,这里说我是空类别,什么情况导致的呀。
有无大佬解答,感谢!
