Use weights_only for load (#3796)

Summary:
`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.
