Code samples contain errors and is missing a function

[krisbock]

Copying the code snippets into a file and executing doesn't work, as the testAccuracy function doesn't test for GPU. So if you are using a GPU and the train function loads the train dataset/model weights onto the GPU, you receive the following error:

RuntimeError: Input type (torch.FloatTensor) and weight type (torch.cuda.FloatTensor) should be the same or input should be a MKLDNN tensor and weight is a dense tensor

Fixing this by adding the following:

images, labels = images.to(device), labels.to(device)

to the testAccuracy function after "images, labels = data"

In addition, the main method calls a testModelAccuracy function that doesn't exist. From the code sample referenced in GitHub (https://github.com/microsoft/Windows-Machine-Learning/blob/master/Samples/Tutorial%20Samples/PyTorch%20Image%20Classification/PyTorchTraining%20-%20Image%20Classification/PyTorchTraining.py), it appears a testClasses function is required.

Problem still exist, any progress?

Closing out these old issues - the pages themselves have been long since changed, and the initial issue should have been resolved (though it was never logged here).
