Installation Error

I am attempting to install via the following commands:

pip install https://github.com/msangnier/qreg/archive/master.zip

With the following error:

Hello, you may try with conda instead of pip.

[jpca227]

Thank you for the recommendation! The result is as follows:

conda install https://github.com/msangnier/qreg/archive/master.zip
Collecting package metadata (current_repodata.json): ...working... done
Solving environment: ...working... failed with initial frozen solve. Retrying with flexible solve.

Try to install pip in conda and use pip directly:

conda install git pip

pip install https://github.com/msangnier/qreg/archive/master.zip

It seems your error is "error: Microsoft Visual C++ 14.0 or greater is required".

If compilation does not work, you can just extract the files, add the path to sys.path, and use alg='qp' instead of alg='sdca'.
Compilation is only for the C++ implementation of sdca. The solver qp is based on cvxopt.
