Approach 1: (works in Jupyterlab but not Voila)

If OpenAI key not set then display input box where users can input the key. It will get saved and run all the below cells again to display the chatbox by running:

app = JupyterFrontEnd()
app.commands.execute('notebook:run-all-below')

The last cell re-running is needed because there's an if condition which checks whether OpenAI API key is set and only if it's set it creates and displays the chat input box.

This works in Jupyterlab:

Screen.Recording.2024-03-25.at.5.22.22.PM.mov

But this doesn't work in Voila, found a related issue: voila-dashboards/voila#614

Screen.Recording.2024-03-25.at.5.21.31.PM.mov

Approach 2 (Works):

Have removed the if openai.api_key != "YOUR_API_KEY" condition altogether from the last cell:

if openai.api_key != "YOUR_API_KEY":
    # chat output
    chat_output = widgets.Output()
    display(chat_output)
    
    # text input
    user_input = widgets.Text(placeholder='Type your message...')
    user_input.on_submit(handle_submit_button)
    display(user_input)
    
    # submit button
    submit_button = widgets.Button(description='Submit')
    submit_button.on_click(handle_submit_button)
    display(submit_button)
else:
    print("**No Open AI key was found. Please update your Open AI key in the notebook before continuing!**")

This will create the chat input box irrespective of whether OpenAI API key is found or not. But it would be disabled till user inputs the API Key. This would eliminate the need to rerun this cell. And user will be prompted for entering the API key when uploading data or using sample data.

I was also getting an error when uploading a file, fixed it by changing this line to uploaded_file = uploaded_files[0]:
