[ML] Manga (Dark Mode)

📃 | Descrição

Este é um projeto simples desenvolvido em Python (training) e TypeScript (proxy/tests), baseado no my-bandwidth-hero, destinado a remover o fundo de mangás. Eu criei isso porque costumo ler mangás principalmente à noite.

Para utilizar este projeto em produção, é necessário instalar a extensão do navegador Bandwidth Hero. Se você preferir ler mangás em um leitor específico, recomendo o TachiyomiAZ, que é compatível com o Bandwidth Hero.

Este projeto foi estruturado e testado com U-Net e Yolov8, utilizando Tensorflow para produção (Tensorflow é compatével com Javascript).

⚠️ Soluções de Erros

Error code: ImportError: cannot import name 'shape_poly' from 'jax.experimental.jax2tf'

Causa: Esse erro é do próprio código.

Solução:

jax-ml/jax#18978 (comment)

# Path: lib/python3.10/site-packages/tensorflowjs/converters/jax_conversion.py

# Remove:
from jax.experimental.jax2tf import shape_poly
PolyShape = shape_poly.PolyShape

# Add:
from jax.experimental.jax2tf import PolyShape

Error code: Wsl/Service/CreateInstance/MountVhd/HCS/ERROR_FILE_NOT_FOUND

Causa: Possivelmente você desistalou e reinstalou o wsl/distro.

Solução:

# List the distributions installed, by running following in PowerShell.
wsl -l

# Unregister the distribution. Replace the "Ubuntu" below with your distribution name found in Step #1:
wsl --unregister Ubuntu-22.04

# Launch the Ubuntu (or other distribution) which was installed using Microsoft Store
