None of the examples in ncvx/examples that use NC-ADMM run properly #9

Closed Shuvomoy closed 6 years ago

Shuvomoy commented 6 years ago

For a personal research project I am trying to reproduce the numerical experiments that use NC-ADMM in the paper:

"A General System for Heuristic Solution of Convex Problems over Nonconvex Sets by S. Diamond, R. Takapoui, and S. Boyd"

and compare the performance with nonconvex Douglas-Rachford splitting.

But none of the examples in ncvx/examples that use NC-ADMM run properly. I followed the instructions exactly as told in Readme, but each of the NC-ADMM examples throws errors. I have Python 2.7, latest Anaconda, CVXPY and NCVX. Any help will be appreciated.

Are you using cvxpy 1.0? ncvx is not yet upgraded to handle cvxpy 1.0. You must use cvxpy 0.4.

Thanks for the info. I could make all the examples (except the traveling salesman problem) work by manually installing cvxpy 0.4.11, ncvx commit 3bf53ca (the newest commit for python 3 does not work) and scsprox. For me that suffices so I am closing the issue.
