pip install . not work in lassen opence-1.9.1 environment.

[DamonLee5]

I am experiencing an issue while attempting to install pysaber in my environment. The installation process fails when trying to install scikit-learn due to a dependency issue related to OpenBLAS.

Currently Loaded Modules:

1. StdEnv (S) 2) gcc/12.2.1 3) spectrum-mpi/rolling-release 4) cuda/11.8.0

Below is the relevant part of the error log for pip install . :

...
Run-time dependency openblas found: NO (tried pkgconfig and cmake)

../scipy/meson.build:169:9: ERROR: Dependency "OpenBLAS" not found, tried pkgconfig and cmake

A full log can be found at /tmp/[temporary-path]/meson-logs/meson-log.txt
...

The issue seems to stem from the OpenBLAS dependency not being found during the build process of scipy, which is a dependency of scikit-learn.

Environment details:

Environment name: opence-1.9.1 in lassen
Python version: 3.9
GCC version: 12.2.1
I attempted to install pysaber via pip install . command in my environment. It seems that the requirement for OpenBLAS is not being met or located correctly.

To fix scipy compile.

Currently Loaded Modules:

1. StdEnv (S) 2) cuda/11.8.0 3) cmake/3.23.1 4) gcc/12.2.1 5) spectrum-mpi/rolling-release

conda install -c conda-forge openblas
export PKG_CONFIG_PATH=$CONDA_PREFIX/lib/pkgconfig:$PKG_CONFIG_PATH

After doing this, scipy can be installed successfully.
However, matplotlib is still not installed by pypi.
Below can be reproduce by pip install matplotlib.

Remove matplotlib from setup.py and using conda install can solve this issue.
