Dialog does not appear when trying to upload a file

Course Q&A AI Python for Beginners
1

Thanks in advance.

Module: AI Python for Beginners: Working with Your Own Data and Documents in Python.

Lesson 2: Loading and using your own data lesson.

The example code works meaning, it runs without errors and gives the expected results. This code allowed me to see the contents of the current working directory:

from helper_functions import upload_txt_file, list_files_in_directory, print_llm_response
list_files_in_directory()

All subsequent code executions were successful until I tried to run:
upload_txt_file()

When I executed this code, no dialog appeared to allow me to upload my own document, and I received no errors in the learning module output.

In Microsoft Edge Version 128.0.2739.67, I set https://deeplearning.ai to “Allow”, in Pop-ups and redirects, but I still don’t get a dialog.

DevTools shows this but I don’t know what to do based on info below.

hello @hroth
The file upload is failing because the Jupyter environment can’t find “jupyter.widget”.
You can try restarting the kernel/runtime, clearing your browser’s cache, or using a different browser.

Hi @hroth ,

Are you running the lab on your own computer?

In any case, make sure you are running all of the cells from top to bottom in a sequential order.

I do this regularly. I understand the importance of the order of execution of the lines in the tutorial. Thank you Mubsi for replying.
