also upgraded and caused

_pickle.UnpicklingError: Weights only load failed. This file can still be
loaded, to do so you have two options, do those steps only if you trust the
source of the checkpoint.
(1) In PyTorch 2.6, we changed the default value of the `weights_only`
argument in `torch.load` from `False` to `True`. Re-running `torch.load` with
`weights_only` set to `False` will likely succeed, but it can result in
arbitrary code execution. Do it only if you got the file from a trusted source.
(2) Alternatively, to load with `weights_only=True` please check the
recommended steps in the following error message.
WeightsUnpickler error: Unsupported global: GLOBAL
torch.nn.modules.container.Sequential was not an allowed global by default.
Please use `torch.serialization.add_safe_globals([Sequential])` or the
`torch.serialization.safe_globals([Sequential])` context manager to allowlist
this global if you trust this class/function.
Check the documentation of torch.load to learn more about types accepted by
default with weights_only
https://pytorch.org/docs/stable/generated/torch.load.html.
