How to check out the source code for opencv-python 3.4.6.27

[samfux84]

Hi,

I have a use case that is a bit special. On our HPC cluster I have an OpenCV 3.4.6 with CUDA and dnn module built. Now I would need the corresponding OpenCV-Python built with CUDA support.

I already tried to install the pre-build 3.4.6.27 version from PYPI, but it is not built with CUDA support. Therefore I would like to try building it from source code.

On our cluster, we already provide newer installations of opencv-python (4.x that does not require a separate OpenCV installation), but for a particular user I would still like to try to get the setup with the old version up and running.

Usually I clone a git repo, then check with

git tag -l

the available tags and then checkout the version that I need. For opencv-python I have a hard time understanding the mapping between the available tags and their corresponding versions. Could you please provide me some help in how I can checkout the source code of opencv-python 3.4.6.27? Due to the --recursive option used for git, I cannot download the 3.4.6.27 realease tarball from your github repository as it does not contain the code for the submodules.

Thank you in advance and best regards

Sam

The version of this repository is the last component of the version string. So clone this repo, update submodules and git checkout 27. However, the setup.py was back then more limited than now so there might be some issues when you try to build it.
