CVXPY installation issues

python cvxpy
σ_clp picture σ_clp · Jun 5, 2018 · Viewed 9k times · Source

I'm trying to install cvxpy on Windows 10 with Python 3.6.5. I've installed Anaconda 5.2 but the package website says that, given my version I should go with pip.

I tried doing so but I'm stuck with these errors. Any help?

(base) C:\WINDOWS\system32>pip install cvxpy

Those errors come from the compilation of ECOS with Microsoft Visual Studio.

Imho you will need the changes to ECOS mentioned here. Those changes were merged into develop-branch (~6 weeks old as of now), but there is a release candidate ecos 2.0.7rc2 ready.

As your automatic setup grabs ecos-2.0.5, i propose doing (in this order):

pip install ecos==2.0.7rc2
pip install cvxpy

I'm assuming here somewhat, that those changes needed for VS 2015 will also be enough for your VS 2017, but no guarantees.

For alternatives, consider this recent approach or setting up a virtual-machine running Linux (which is my way to go most of the time).
