pytorch報錯：UserWarning: invalid index of a 0-dim tensor. This will be an error in PyTorch 0.5.。。原因

UserWarning: invalid index of a 0-dim tensor. This will be an error in PyTorch 0.5. Use tensor.item() to convert a 0-dim tensor to a Python number

當報這個錯的一般會有兩個原因，一個是這種寫法：

loss.data[0]

應該改成loss.item()

還有就是這種寫法：

im = Variable(im.cuda()，volatile=True）

應該改成im = Variable(im.cuda())
