I am trying to create specific python environment inside docker for reproducible builds, but package python-opencv
that previously was manually installed refuses to get installed with error:
ERROR: Could not find a version that satisfies the requirement opencv_python==4.7.0 (from versions: 3.4.0.14, 3.4.10.37, 3.4.11.39, 3.4.11.41, 3.4.11.43, 3.4.11.45, 3.4.13.47, 3.4.15.55, 3.4.16.57, 3.4.16.59, 3.4.17.61, 3.4.17.63, 3.4.18.65, 4.3.0.38, 4.4.0.40, 4.4.0.42, 4.4.0.44, 4.4.0.46, 4.5.1.48, 4.5.3.56, 4.5.4.58, 4.5.4.60, 4.5.5.62, 4.5.5.64, 4.6.0.66, 4.7.0.68)
ERROR: No matching distribution found for opencv_python==4.7.0
Command was:
pip3 install face_recognition==1.3.0 opencv_python==4.7.0
Inside docker: ubuntu 22.04; Python 3.10.6; pip 22.0.2
Why pip3 cannot find opencv_python
version 4.7.0
since it's clearly in the list of available packages? What's the best way to create reproducible python environment when building docker image?
You need to specify the exact version, so:
opencv_python==4.7.0.68
Otherwise, you can ask for approximate versions using one of the following:
opencv_python~=4.7.0
opencv_python==4.7.0.*
