Hi @Sophia

From the following error, it seems that you’re missing a dependency from the OS

You can add this package in the packages.txt file.

6

Afaik none of the above mentioned python libraries require any additional OS package.
The error message from post#1 may result from a prior version of the requirements file.

the requirements are correct. But I can’t access the webcam that is in my code on the streamlit cloud. What do I need to change cause it works perfectly fine on the local environement

  • Which python file are you referring to?
  • You cannot use cv2.VideoCapture() on streamlit cloud
9

I’m referring to the age_gender.py file

and yes, I can’t use the cv2.VideoCapture(0)

  • You have to go for another approach for example with streamlit-webrtc or a similar streamlit component.
  • Btw, webbrowser will also not work on streamlit cloud.

I have now changed the webcam to streamlit-webrtc and it works perfectly fine on my local network but as soon as I start it on the streamlit cloud it opens a video frame and after pressing the start button it loads forever, then showing a black screen and closes again. But I don’t get any Error message.

and I’ve added a test.py file to try out the webcam but it’s the same problem. It works on the local network but not on the streamlit cloud

Hi @Sophia

Have you tested this on a different computer or from a different internet provider or even check if proxy is preventing this.

Also there’s a related post to this here:

Hope this helps!
