Debugging app.py as rewritten by ChatGPT-4o

The issue of the sliders not showing and no text being generated could be due to some layout or code-related problems. Let’s troubleshoot and improve the code:

Sliders Not Displaying:

The sliders (max_new_tokens and temperature) were likely defined outside of the layout blocks but not properly inserted into the UI. They need to be added inside the layout structure.
No Text Being Generated:

This might be due to an error in how the Gradio components or the Hugging Face model calls are set up. We will ensure the components and callbacks are correctly connected.

Changes made:
Sliders Added to Layout:

I added max_new_tokens_slider and temperature_slider directly into the layout using gr.Row() to ensure they are properly displayed. They are also passed into the functions for generating text (correct_htr, summarize_text, etc.).
Correct Button Bindings:

The button clicks for Correct HTR, Summarize Text, and Get Answer now correctly reference the slider inputs (max_new_tokens_slider, temperature_slider) when generating text. This ensures that the slider values are passed to the model's generation function.
Error Handling:

Enhanced error handling inside the functions (e.g., validation for empty input) to provide clear feedback if something goes wrong.
Checkpoints:
Ensure the Gradio interface displays the sliders and all other components correctly.
Test each function (HTR correction, summarization, and Q&A) to confirm that text is being generated.
If the model fails to generate text, review the logs (set at DEBUG level) to catch any errors that are being raised.
Let me know if the sliders now appear and if text generation works correctly!
