Independent whether I install using pip or from source, whether I use python2 or python3 I can't install cvxpy. I've tried now over four hours and I still fail. The github pages of cvxpy or qdldl wouldn't give me any solution. I installed the packages which led to other errors with no success. Any hints are appreciated.

Disabling LONG
Remove long integers for numpy compatibility. See:
- https://github.com/numpy/numpy/issues/5906
- https://github.com/ContinuumIO/anaconda-issues/issues/3823
You can reenable long integers by passing: --osqp --long argument.
