Could not install from pip on PowerPC architecture. GCC output: c++: error: unrecognized command line option ‘-march=native’
I found another project where it caused problems: mfem/mfem#216

The solution is to clone this repository and edit CMakeLists.txt - just remove -march=native. Then execute pip install . from the repository directory.
The speed difference is real!
