Hi,everyone,
I am leaning the PyTorch tutorials, and I find that in the codes below, if I miss _,
in front of ‘predicted’ in the second line, I’ll meet the error ‘only integer tensors of a single element can be converted to an index’, if I add _,
in front of it, there’ll be no problems. Could anyone tell me what _,
do and how _,
do it? Thank you:)
outputs = net(images)
_, predicted = torch.max(outputs, 1)
print('Predicted: ', ' '.join('%5s' % classes[predicted[j]]
for j in range(4)))
‘net()’ is a CNN defined before, you can see it in Deep Learning with PyTorch: A 60 Minute Blitz > Training a Classifier
