Hi @firstime09

The ModuleNotFoundError suggests that you’re missing a required prerequisite library. Could you try adding opencv-python-headless to your requirements.txt file.

Also see this related forum post Getting No module cv2 found - #2 by jgieseler

Hope this helps!

Sometimes the package opencv-python-headless is giving errors with python 3.9 version in the streamlit cloud @dataprofessor. Instead of that use
opencv-python-contrib-headless.

Hi @dataprofessor

Thank you for your response about that.
I will try your advice, by the way, I know you from YouTube videos, and some of your videos about Streamlit it is really helpful for me.

Hi @firstime09

There’s actually a similar post on the error

please find the post at the following link

In a nutshell, this would entail adding prerequisite libraries to your requirements.txt file.

Hope this helps!

Thank you so much for your help @dataprofessor @djshan1979, now my simple Streamlit web app fftampinongkol.streamlit.app is all ready to be used.
And I hope you can give me some input for the next development.
