Where are the exported png files generated by my script saved?

My script involves:

  • Calling API and consolidating the data into a pandas dataframe
  • Converting and exporting the dataframe into a png file using dataframe_image library
  • A chatbot will send the png file to the user

When I run the script on my desktop, the png will be saved in my drive. But when I run on pythonanywhere, I am unsure where is my png file located at. Thus, my bot does not send any response to my users.

Any advice is appreciated, thank you.

Sorry Glenn, I should have been more specific and state the exception. I thought it's the file path that's causing the issue but I've tried the suggestion above but to no avail.

Here's the traceback. I'm met with a CalledProcessError but I don't have this issue when I'm running the script on my desktop.

Any idea why this might be so?

It looks like an issue with using dataframe-image on PythonAnywhere. I found a previous forum post where a user suggests using df2img instead. Maybe you can try if that works.
