5 years ago I don't know much about SCS, but it seems this is serving as internal solver at some point, which relies on blas+lapack. Then, as an alternative solution, is there a way that I can rather change it to some other solver? Otherwise it feels more convenient for me to learn how to just make (blas+lapack) work properly.

5 years ago Here is what I have just tried. Is there a guideline to do this step-by-step on Windows10? I can reinstall whatever necessary from scratch. Thanks.
//----------------------------------------------------------------------------------------- { 01. [install] pip install ./"numpy-1.15.4+mkl-cp35-cp35m-win_amd64.whl"
{ >> conda list
[if multiple versions of numpy]
conda uninstall numpy_bla_bla,
pip uninstall numpy_bla_bla.
}
https://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy
"Unofficial Windows Binaries for Python Extension Packages" offers,
.whl files so that you can choose specific versions pre-compiled.
cp35 means python 3.5,
win_amd64 means x64.
{ [test install] with .py
import numpy
print(numpy.version.version)
numpy.show_config()
}} { 02. [install] pip install ./"cvxpy-0.4.10-py3-none-any.whl"
https://pypi.org/project/cvxpy/0.4.10/#files
[why lower-version] because
(!) qcqp 0.8.3 has requirement cvxpy<1.0, but you'll have cvxpy 1.0.12 which is incompatible.

{ [test install] with .py
