why my experiment results can't reach the original performance?

[JaminLi]

Hi, thanks for your nice repo! When I used your method for my experiment, I found my experiment results can't reach the original performance whether the first iteration or the 35th iteration.

In <main.py> #Freezing Pruned weights by making their gradients Zero grad_tensor = np.where(tensor < EPS, 0, grad_tensor)

Does this issue?

In my implementation, I refactored all of the NumPy operations to the PyTorch ones. It worked, and the accuracy can reach training from scratch.
