How to get these data(means = [0.485, 0.456, 0.406] stds = [0.229, 0.224, 0.225]) in your code?

[zhangrong1722]

In your code same data is as follows:
means = [0.485, 0.456, 0.406] stds = [0.229, 0.224, 0.225]
These are not standard deviation and mean of single image(both.png in your project).And I wonder how to get these data.
Thank you!

This is from the imagenet data.

It is the mean and std of the train dataset, you may calculate it and then normalize the train dataset. https://discuss.pytorch.org/t/normalization-in-the-mnist-example/457/10
