Build Highs - for Pyhton highspy with hipo/blas

[Tooblippe]

Hi,

i was able to build Highs 1.3.1 from sources for:
a) hipo/blas and also
2) cuda and both worked.

I also want to compile highspy to run with pypsa but it gives error ERRORHIPO is only available in C++. Not yet supported in Python. - is it possible to build highspy yet for the new implementation.

I ran `pip install .' against the pyproject.toml with the Blas and Hipo Cmake flags set. It runs to almost completion and then the error - Process failed with very little further info.

thanks
Tobie

Hi Tobie,

We are currently working on HiGHS with HiPO in Python. There is some more work to do, as we want to keep HiPO optional. Please note, that using HIPO changes the license from MIT to Apache.

For the moment, you can use the developemnt version from conda-forge with

 conda install -c conda-forge/label/dev highspy

Or you could build it locally, if you check out branch py-l2 and run

 python -m pip install .  --config-settings=cmake.define.HIPO=ON  --config-settings=cmake.define.BUILD_OPENBLAS=ON

These build steps will change with our ongoing re-structure of the dependency management

Thank you for the detailed reply.

Will follow guidelines and see if i can get it to work.
