Libraries used

requirements.txt
numpy
opencv-python-headless
mediapipe

Hi @karim-abdulnabi . Instead of opencv-python-headless use opencv-python-contrib-headless.

[karim-abdulnabi]

@Guna_Sekhar_Venkata . I changed it but not work also

[Guna_Sekhar_Venkata]

hi @karim-abdulnabi . could you share the code block of error?

@Guna_Sekhar_Venkata

could you share the code block of error?

[Guna_Sekhar_Venkata]

hey @karim-abdulnabi i have seen your github repo. You mentioned requirements.txt file in Sing_Language_Project/st_project/requirements.txt. Instead of there, move it to the root directory (Sing_Language_Project) where streamlit can first see the requirements.txt before building the app. So move requirements.text to the root folder named Sing_Language_Project.

Sing_Language_Project
      --- requirements.txt
      --- rest of the sub directories

Use the follows names in your requirements.txt as follows:

numpy
opencv-contrib-python-headless
streamlit_webrtc==0.47.0
av==10.0.0
deepface==0.0.75
mediapipe==0.9.0.1
tensorflow-cpu==2.13.0

After implementing the modifications, the same problem appears

[Guna_Sekhar_Venkata]

sorry i have shared wrong directory structure. Follow:

Signe_Language
      --- requirements.txt
      --- Sing_Language_Project
      --- README.md

[karim-abdulnabi]

the same error

[Guna_Sekhar_Venkata]

@karim-abdulnabi , You are using which python version of your cloud and what is the use of tensorflow-cpu pacakge?

[karim-abdulnabi]

@Guna_Sekhar_Venkata
python 3.10.9
cv2 4.9.0
streamit 1.31.1

[Guna_Sekhar_Venkata]

Hey @karim-abdulnabi delete the app once and redeploy the app by selecting the python version as 3.9. Don’t mention any specific version of package in the requirements.txt file. Im hoping that it should work now.

Happy Streamlit-ing

@Guna_Sekhar_Venkata , not work But a change in error

[Franky1]

• Remove opencv from the requirements file, it is useless in this specific case, because mediapipe overrules this anyway and enforces the installation of a non-headless opencv version.
• I think there are still missing dependencies in the requirements file.
• Move both packages.txt and requirements.txt to the root folder of the github repo.
• Do a reboot of the streamlit app

[karim-abdulnabi]

@Franky1 , Yes, there were some requirements that I added, but they did not work either
