Use weights_only for loading

[kit1980]

torch.load without weights_only parameter is unsafe. Explicitly set weights_only to False only if you trust the data you load and full pickle functionality is needed, otherwise set weights_only=True.

If weights_only=True doesn't work for some cases, then explicit weights_only=False should be used.
