Problem in generating .mokuro and .html files.

[hiderkee]

Lately, I have to reset my laptop and reinstall mokuro, following the steps on Lazy Guide (except for the CUDA step which is optional). However, I kept getting this error message: "RuntimeError: PytorchStreamReader failed reading zip archive: failed finding central directory" and the _OCR folder appeared with nothing inside.

Before resetting, mokuro can generate .html files without any problem.

My input:
mokuro /Users/npk/Documents/Nana/v01

The following output:

`2024-07-11 20:48:47.899 | WARNING  | mokuro.run:run:55 - Legacy HTML output is deprecated and will not be further developed. It's recommended to use .mokuro format and web reader instead. Legacy HTML will be disabled by default in the future. To explicitly enable it, run with option --legacy-html.

2024-07-11 20:48:57.385 | INFO     | mokuro.run:run:146 - Processed successfully: 0/1`

I use:
MacOS Monterey 12.7.5,
Python 3.10.11,
Pip 23.0.1,
And just install mokuro v0.2.1.

I hope to find a solution to this issue soon. I am not very tech-savvy, but I will do my best to understand. Thank you in advance.

Seems like the model file is corrupted. Try downloading it manually from: https://github.com/zyddnys/manga-image-translator/releases/download/beta-0.2.1/comictextdetector.pt

and replace this file: /Users/npk/.cache/manga-ocr/comictextdetector.pt

Thank you very much @kha-white!!
I replaced the file you mentioned. It worked at first, however, another error appeared. It looks like this:

NotImplementedError: The operator 'aten::isin.Tensor_Tensor_out' is not currently implemented for the MPS device. If you want this op to be added in priority during the prototype phase of this feature, please comment on https://github.com/pytorch/pytorch/issues/77764. As a temporary fix, you can set the environment variable `PYTORCH_ENABLE_MPS_FALLBACK=1` to use the CPU as a fallback for this op. WARNING: this will be slower than running natively on MPS.

I hope it won't bother you since I have no clue in where or why the problems occur. If it is possible, could I try downloading the older version of mokuro?

[kha-white]

Older version mokuro is unlikely to help, seems like issue was introduced by this change in transformers library and patch in Pytorch was needed, see pytorch/pytorch#124518

You might check if nightly Pytorch build fixes this for you, or try running PYTORCH_ENABLE_MPS_FALLBACK=1 in console before running mokuro, but this might be a bit slower than running fully on MPS.

I am also currently experiencing this on Fedora with python 3.12.4
