Hello,

Are you using opencv?

dheerajk-devTRIAL

yes

brodyEMPLOYEE

Try replacing it with the headless version.

Try replacing it with the headless version.

dheerajk-devTRIAL

I have already replaced with 

opencv-python-headless==4.8.0.74

but not worked. same issue I am getting

brodyEMPLOYEE

I would have to say that another package is downloading the non headless version still.

Yep, if you search your logs for opencv_python the non headless version is indeed being installed.

Try setting a NIXPACKS_INSTALL_CMD service variable to -

python -m venv --copies /opt/venv && . /opt/venv/bin/activate && pip install -r requirements.txt && pip uninstall -y opencv_python

where I should set this variable? in env variables?

brodyEMPLOYEE

As a service variable -

https://docs.railway.com/overview/the-basics#service-variables

Also, FWIW, we are the only two users in this thread, so replying to every message doesn't make a difference.
