[2025-02-18T15:24:11.855Z] _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. 

[2025-02-18T15:24:11.855Z] 	(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.

[2025-02-18T15:24:11.855Z] 	(2) Alternatively, to load with `weights_only=True` please check the recommended steps in the following error message.

[2025-02-18T15:24:11.855Z] 	WeightsUnpickler error: Unsupported global: GLOBAL monai.utils.enums.MetaKeys was not an allowed global by default. Please use `torch.serialization.add_safe_globals([MetaKeys])` or the `torch.serialization.safe_globals([MetaKeys])` context manager to allowlist this global if you trust this class/function.
