Pytorch slow on Windows 10

i installed pytorch+cuda through the pip command provided on their website.
While following part one, when he trains the first model, he said that it shouldnt take more than 5 minutes.
Well, that first block took me 9 minutes, even though i have a decent GPU (GTX 1070).
Did i do something wrong?

Please let me know if you need any extra info.

Thank you for your time!

you mean the cat/dog recognizer model? I got a jupyter server which powered by RTX 2070 Super GPU, that model training took 1.5 minite, seems the training time depends on the device’s performance. Or, you may try to use a simple network, like resnet18, determine if the trainging time will reduce.
