Noo module named slycot #63
Description
Activity
pip install cmake
Probably isn't doing what you think it should. You should
apt install cmake.I take that back. It actually seems like cmake is packaged for installation via pypi: https://pypi.org/project/cmake/
I also tried to install slycot from source which leads to the same issue.
Cmake is of course installed on my system.Are you sure you have installed the package into a directory that is on your path? Are you trying to import from the same Python executable that the package was installed alongside?
Ah-ha; the files have been installed in "slycot" off the virtual-env root, rather than in site-packages; I remember this happening on Windows when I was trying to build wheels there, but I thought it was a peculiarity of that environment. The result below is from an Ubuntu 18.04 system.
If anyone knows why this would happen, please speak up. Do we need to teach scikit-build or CMake about the "normal" install directories, maybe?

Hi,
I recently tried to install slycot via pip. Before that I installed the following dependencies:
Everything installs without any errors, but when I am trying to import slycot, I get the following error message:
ModuleNotFoundError: No module named 'slycot'Am I missing something?
