Nougat-LaTeX-based is fine-tuned from facebook/nougat-base with im2latex-100k to boost its proficiency in generating LaTeX code from images. Since the initial encoder input image size of nougat was unsuitable for equation image segments, leading to potential rescaling artifacts that degrades the generation quality of LaTeX code. To address this, Nougat-LaTeX-based adjusts the input resolution and uses an adaptive padding approach to ensure that equation image segments in the wild are resized to closely match the resolution of the training data.

1. Prepare your dataset in this format
2. Change config/base.yaml
3. Run the training script

python tools/train_experiment.py --config_file config/base.yaml --phase 'train'

from transformers import pipeline
pipe = pipeline("image-to-text", model="Norm/nougat-latex-base")

from transformers import AutoTokenizer, AutoModel
tokenizer = AutoTokenizer.from_pretrained("Norm/nougat-latex-base")
model = AutoModel.from_pretrained("Norm/nougat-latex-base")
