WeightsUnpickler error: Unsupported global: GLOBAL transformers.models.bert.tokenization_bert_fast.BertTokenizerFast was not an allowed global by default. Please use `torch.serialization.add_safe_globals([BertTokenizerFast])` or the `torch.serialization.safe_globals([BertTokenizerFast])` context manager to allowlist this global if you trust this class/function.

_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.
