I need to create env with
mamba create --name tf1_12__HDR Tensorflow==1.12.0 Keras==2.2.4 opencv-python==3.4.4.19 anaconda
It provides
mamba (0.7.3) supported by @QuantStack
...
Looking for: ['tensorflow==1.12.0', 'keras==2.2.4', 'opencv-python==3.4.4.19', 'anaconda']
...
Problem: nothing provides requested opencv-python 3.4.4.19
I am calling
pip install opencv-python==
ERROR: Could not find a version that satisfies the requirement opencv-python== (from versions: 3.4.2.17, 3.4.3.18, 3.4.4.19, 3.4.5.20, 3.4.6.27, 3.4.7.28, 3.4.8.29, 3.4.9.31, 3.4.9.33, 3.4.10.35, 3.4.10.37, 3.4.11.39, 3.4.11.41, 3.4.11.43, 3.4.11.45, 3.4.13.47, 3.4.14.51, 3.4.14.53, 3.4.15.55, 3.4.16.57, 4.0.0.21, 4.0.1.23, 4.0.1.24, 4.1.0.25, 4.1.1.26, 4.1.2.30, 4.2.0.32, 4.2.0.34, 4.3.0.36, 4.3.0.38, 4.4.0.40, 4.4.0.42, 4.4.0.44, 4.4.0.46, 4.5.1.48, 4.5.2.52, 4.5.2.54, 4.5.3.56, 4.5.4.58)
ERROR: No matching distribution found for opencv-python==
So such version exists.
I know a cheat to overcome issue using steps:
1 Create env without opencv-python
2 Install opencv-python with pip
but it can lead to conflicts inside enviroment and potentially break it.
Can you please provide a "clean" solution and/or describe the reason of this unexpected output?
PyPI and Anaconda Cloud packages don't necessarily go by the same names. The opencv package from Conda Forge will include the OpenCV libs (libopencv) and the Python interface (py-opencv). That is, install opencv with the version you want.
BTW, as mentioned in the comments == is Pip syntax, Conda/Mamba use single =.
