Error while deploying an app with mediapipe

@ajaygithub2 Try this one: requirements.txt streamlit mediapipe packages.txt libgl1-mesa-glx libglib2.0-0 test.py import streamlit as st import cv2 import mediapipe as mp print(st.__version__) print(cv2.__version__) print(mp.__version__) gave me the folowing log output in a Python 3.9. environment 1.21.0 4.7.0 0.9.2.1 The above quick solution should work. IMHO the problem with mediapipe is, that it enforces the installation of a non-headless version of opencv, which causes issues in a…

@NithinM29602 you can try to use pipreqs to automatically generate your requirements.txt and try to reboot the website again, watch this article here: How to Auto Generate requirements.txt (Dependencies) in Python - 3 examples

Tried it, But Same error is popping out Bro

Hey @NithinM29602

You need to move your packages.txt to the root of GitHub repository. i.e. out of the Streamlit/ directory.

And you only need to include one package libgl1 in packages.txt.

Once you make the two changes, you should no longer see the ImportError: libGL.so.1: error:

We will better highlight the need for packages.txt to be in the repo root in our Community Cloud documentation:

App dependencies - Streamlit Docs

If packages.txt exists in the root directory of your repository we automatically detect it, parse it, and install the listed packages. You can read more about apt-get in Linux documentation.

Happy Streamlit-ing!

[NithinM29602]

Thanks Bro, The problem was resolved.
But I got another problem, The frames from the webcam is not displaying out there.

[Guna_Sekhar_Venkata]

If the model is very high, then it’s impossible with the streamlit to do frame to frame detection. Unfortunately streamlit doesn’t work for large object detection models.

[Guna_Sekhar_Venkata]

But there is an possible solution. Instead of frame to frame detection, we can capture the image and do prediction with the help of st.camera_input(). For more reference:-

https://poth-holes-detector-system-with-bboxes-v1.streamlit.app/

[NithinM29602]

Thanks for the Information.

st.camera_input() is used to capture the photo right. But I need the real time video frames, so that the model can process those frames and display back to the user.
If there is any other Information related to that, Please share it.

After successful run for a few seconds the video capture stopped and showed these error logs

It’s possible with streamlit webrtc package. Once google it, you can find the results
