getting pytorch issue

[tshrinivasan]

cat test.py
from ocr_tamil.ocr import OCR
#https://github.com/gnana70/tamil_ocr


image_path = r"a.png" # insert your own path here
ocr = OCR()
text_list = ocr.predict(image_path)
print(text_list[0])

for the above code, getting below error.

python3 test.py

_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 ocr_tamil.strhub.models.parseq.system.PARSeq was not an allowed global by default. Please use `torch.serialization.add_safe_globals([PARSeq])` or the `torch.serialization.safe_globals([PARSeq])` 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.

Thanks for reporting this. Will look into it
