Fix Code Error

[IlanVinograd]

from torchmetrics import Accuracy

acc_fn = Accuracy(num_classes=len(fashion_mnist_class_names)).to(device)

This line must be fixed because it giving error -> Traceback (most recent call last):
File "D:\Visual Studio Projects\PyTorch\PyTorch.py", line 124, in
acc_fn = Accuracy(num_classes=len(fashion_mnist_class_names))
TypeError: new() missing 1 required positional argument: 'task'
Press any key to continue . . .

this may be due to updates to the torchmetrics library, where creating an instance of the Accuracy class now requires an important function for which the metric is stored.

fixed line:

from torchmetrics import Accuracy

acc_fn = Accuracy(num_classes=len(fashion_mnist_class_names), average='macro', task='multiclass')
