Cannot find the requested files in the cached path.

Without internet connection, running MangaOcr returns this error:

File "manga_ocr\ocr.py", line 15, in __init__
    self.tokenizer = AutoTokenizer.from_pretrained(pretrained_model_name_or_path)
  File "transformers\models\auto\tokenization_auto.py", line 528, in from_pretrained
    return tokenizer_class.from_pretrained(pretrained_model_name_or_path, *inputs, **kwargs)

    "Connection error, and we cannot find the requested files in the cached path."
ValueError: Connection error, and we cannot find the requested files in the cached path. Please try again or make sure your Internet connection is on.

I’m sure the first time I ran MangaOcr, it downloaded the pretrained model, but it seems it can’t find it. Where was the model saved at? I’ve search around but no luck. I’m using python with anaconda on Windows 10.

And anyway, thanks for the work. Does its job flawlessly.

Thank you very much, setting the env variable solves the problem. Also cuts down on loading times: from 10 seconds to 2! No more issues after this.

Huh, to be honest I thought it’d work out of the box, but apparently transformers need to be explicitly told to use offline cache: https://huggingface.co/docs/transformers/installation#offline-mode

So, there are two options:

1. Set environment variable TRANSFORMERS_OFFLINE=1 and run normally (it should use cache).

or

1. Download model files from https://huggingface.co/kha-white/manga-ocr-base/tree/main and pass the path to folder containing these files as pretrained_model_name_or_path parameter.
