After you cd to the directory where you have your app, can you run dir to look at the displayed files and folders and make sure it is the same location you think it is? Maybe it got saved under some other profile folder or it is redirected.
Another thing you can do is navigate to where you have the file saved and right click on it, select Properties. Confirm the full file path there.
hello, thanks for the earlier solution, however I’m still getting the same error. I believe my files aren’t still in the same directory, will try troubleshooting a bit more.
The file you are pointing to is app.py.ipynb. Is this a notebook or a plain Python script? Streamlit needs a .py file, not a .ipynb file. Make sure you have it saved with the right extension.
