RuntimeError: Error(s) in loading state_dict for Model: size mismatch for Prediction.weight: copying a param with shape torch.Size([143, 512]) from checkpoint, the shape in current model is torch.Size([127, 512]). size mismatch for Prediction.bias: copying a param with shape torch.Size([143]) from checkpoint, the shape in current model is torch.Size([127]).

I have a similar issue even on 1.6.2. Also tried 1.7.1 - same error.

RuntimeError: Error(s) in loading state_dict for DataParallel:
        size mismatch for module.Prediction.weight: copying a param with shape torch.Size([103, 256]) from checkpoint, the shape in current model is torch.Size([97, 256]).
        size mismatch for module.Prediction.bias: copying a param with shape torch.Size([103]) from checkpoint, the shape in current model is torch.Size([97]).

Please check this repo if you are interested in tamil ocr. It's capable of recognizing both tamil and English. https://github.com/gnana70/tamil_ocr

You can simply install using pip install ocr_tamil

from ocr_tamil.ocr import OCR
image_path = r"test_images\0.jpg" # insert your own path here
ocr = OCR(detect=True)
texts = ocr.predict(image_path)
with open("output.txt","w",encoding="utf-8") as f:
    f.write(texts)
