The error has something to do with the following - Failed building wheel for ecos
Initially it was showing me error with the visual studio c++ and after installation of VS 2015 C++ Build Tools it still gave a similar error, but this time if was due to something else. I haven't been able to figure out a way to fix this. Will appreciate some help with this.
Thanks in advance!
Ran into the same problem (ecos 2.0.4) and came upon this thread: ecos python issue
Solved the problem by manually downloading the appropriate .whl file (Python version and Windows architecture): Windows binaries
Navigated to the downloaded file (in terminal) and ran pip install filename.whl.
