Gradio -- gr.File() is not working for downloading txt

Spaces
1

I’m having some trouble with simply saving .txt results as downloadable using Gradio’s File() method.

Referencing the docs: Gradio Docs

Additionally, here is a related example on a space: app.py · radames/dpt-depth-estimation-3d-obj at main

However, this is using Gradio version 4.26.0 and saving a different file type; I am using 5.42.0;

When I attempt to download my results, my browser shows “File wasn’t available on site” in the downloads section.

Here is the code:

import gradio as gr
import json
import os
from datetime import datetime
from pathlib import Path

gr.set_static_paths(paths=[Path.cwd().absolute()])
                    
print("Current Working Directory: ", os.getcwd())
cwd = os.getcwd()

def process_question(question):
    try:
        answer = {"doc1": "document 1 contents", "doc2": "document 2 contents"}
        # Create file in current directory with timestamp
        timestamp = datetime.now().strftime("%Y%m%d_%H%M%S")
        filename = f"my_answer_{timestamp}.txt"# Get the current working directory
        filepath = os.path.join(cwd, filename)

        f = open(filename, "w", encoding="utf-8")
        try:
            answer = json.dumps(answer, indent=2, ensure_ascii=False)
            f.write(answer)
        finally:
            f.close()

        return [answer, filepath]
    
    except Exception as e:
        return f"Error processing question: {str(e)}", None

# Create Gradio interface
iface = gr.Interface(
    fn=process_question,
    inputs=gr.Textbox(label="Ask a question about documents", placeholder="Extract the text from this document."),
    outputs=[
        gr.Textbox(label="Answer"),
        gr.File(label="Download Answer as txt", file_count="single", file_types=[".txt"], type="filepath" )

    ],
    title="Document Reader",
    description="Ask questions about documents using AI vision to read scanned PDFs"
    )

iface.launch(ssr_mode=False, allowed_paths=[cwd])

Take note: I also outputted the filename from the process_question() with the same result

When I attempt to right click on the download link and open as a new tab, I’m met with a 404 error and the address URL is https://huggingface.co/proxy/myhfspace.hf.space/gradio_api/file=answer.txt (note: I’ve changes the name, but it’s similar)

If anyone has any idea how to get this to work, it would be appreciated.

When porting Gradio 4 code to Gradio 5, most of it will work as is, but there are a few exceptions. File access is one of them. If allowed_paths is not set appropriately, access will be denied. In rare cases, using gr.DownloadButton instead of gr.File may provide more stable results.
