Why i'm getting this error my application is running fine in my pc

File "/home/appuser/venv/lib/python3.9/site-packages/streamlit/scriptrunner/script_runner.py", line 557, in _run_script
    exec(code, module.__dict__)File "disease_prediction.py", line 1, in <module>
    from tkinter import *File "/usr/local/lib/python3.9/tkinter/__init__.py", line 37, in <module>
    import _tkinter # If this fails your Python may not be configured for Tk

Did you forget to paste the actual error message?

Anyway, I don’t think you can install tkinter in streamlit cloud. That is probably why you are getting that error.
