"MUMPS is not available"
Hi,
I just installed Kwant. I'm working with Ananconda. I installed all the packages adviced (even those which are not needed like MUMPS) with the command "conda install -c conda-forge namepackage". It worked for all the packages except Kwant. I had an issue saying me that the chanel was not found (which is weird because the chanel was still conda-forge but i read that it seems to be a recurring issue with some packages). So i tryed to install Kwant directly from the wheel file using python "-c "import pip, glob; pip.main(['install', '--no-deps'] + glob.glob('*.whl'))" " on the terminal. An error raised saying pip needed to be update to version 10.0, which i did. Tryed the command again , had another error raised saying "pip has no attribute main". So i used "pip install --no-deps *.whl" instead, it worked, now i can used kwant package but when i import Kwant i have this warning message " C:\ProgramData\Anaconda3\lib\site-packages\kwant\solvers\default.py:18: RuntimeWarning: MUMPS is not available, SciPy built-in solver will be used as a fallback. Performance can be very poor in this case. "Performance can be very poor in this case.", RuntimeWarning) ".
Does kwant will use MUMPS despite this message? If not do you know what can i do to make it use it? How much MUMPS improves Kwant runetime?
TY
