ModuleNotFoundError: No module named 'streamlit.report_thread'

Streamlit Cloud
#1

I’m trying to deploy an object detection web app on streamlit cloud but it’s throwing me this error

File “/home/appuser/venv/lib/python3.7/site-packages/streamlit_webrtc/session_info.py”, line 1, in
import streamlit.report_thread as ReportThread

the app runs fine on my local setup

here is the github repo of the project

here is the piece of code from the file which i think throws the error

Hello @Aditya_Chache, welcome to the community!

We’ve seen the issue appear this morning with the new 1.4.0 release, for now if you are in a hurry you can downgrade back to streamlit==1.3.1.

Do you use any old Session State code or external Streamlit package aside from streamlit-webrtc ? That will help the team diagnose the problem.

PS: wait, I think, @whitphx are you calling streamlit.report_thread in streamlit-webrtc ? I submitted an issue ModuleNotFoundError: No module named 'streamlit.report_thread' on Streamlit 1.4.0 · Issue #598 · whitphx/streamlit-webrtc · GitHub

Have a nice day,
Fanilo

Thank you so much for solving the problem.
I just downgraded back to version 1.3.1 and now everything works fine

Hi, thank you for the report.
I updated streamlit-webrtc and released a new version.
streamlit-webrtc>=0.34.1 should work with streamlit==1.4.0.
