I'm sorry for submitting multiple pull requests with the same proposal. I had an organizational email account that did not have CLA Google verification. 🤦‍♂️

Thank you for the pr, I tested on my local machine, and using this version of numpy leads to

ERROR: Cannot install -r requirements.txt (line 10), -r requirements.txt (line 2), -r requirements.txt (line 4) and numpy==2.1.2 because these package versions have conflicting dependencies.

The conflict is caused by:
    The user requested numpy==2.1.2
    gradio 5.4.0 depends on numpy<3.0 and >=1.0
    matplotlib 3.9.2 depends on numpy>=1.23
    tensorflow 2.15.0 depends on numpy<2.0.0 and >=1.23.5

At the moment we recommend using Google Colab, together with our colab file which includes all necessary dependency installations to help you get started.

This list might work but it's not thoroughly tested:

gdown==5.2.0
gradio==5.4.0
jupyter
matplotlib==3.7.1
numpy==1.26.4
Pillow==10.4.0
pytesseract==0.3.13
Requests==2.32.3
tensorflow==2.15.0
tensorflow_text==2.15.0
tqdm==4.66.6
