example MPT quantization doesn't work

Followed this guide : https://github.com/ggerganov/ggml/tree/master/examples/mpt When tried to cast model to fp-16, got following error :

• Loading part: pytorch_model-00001-of-00007.bin Traceback (most recent call last): File "/mnt/j/ggml/examples/mpt/convert-h5-to-ggml.py", line 133, in model_part = torch.load(f"{dir_model}/{part_name}", map_location="cpu") File "/home/_username/.local/lib/python3.10/site-packages/torch/serialization.py", line 815, in load return _legacy_load(opened_file, map_location, pickle_module, pickle_load_args) File "/home/_username/.local/lib/python3.10/site-packages/torch/serialization.py", line 1033, in _legacy_load magic_number = pickle_module.load(f, pickle_load_args) _pickle.UnpicklingError: invalid load key, 'v'.

Maybe guide/code should be updated

_pickle.UnpicklingError: invalid load key, 'v'.

It looks like your model files are corrupted. Try download them again.
