Obspy installation error: 'ERROR: Dependency "OpenBLAS" not found'

Question

I am trying to install obspy on my raspberry pi but I keep getting this error:

  note: This error originates from a subprocess, and is likely not a problem with pip.
error: metadata-generation-failed

× Encountered error while generating package metadata.
╰─> See above for output.

note: This is an issue with the package mentioned above, not pip.
hint: See above for details.

I have tried lots of things including:

sudo apt-get install build-essential gfortran

installing scipy separately: pip3 install scipy

pip3 install --upgrade pip

pip3 cache purge

sudo apt-get update
sudo apt-get upgrade

sudo apt-get install cmake

sudo apt-get install libatlas-base-dev

pip3 install --upgrade pip setuptools

And, also trying to install obspy in a virtual environment using python3 -m virtualenv obspy_env and source obspy_env/bin/activate.

I always get the same error that "Preparing metadata did not run successfully". I have pasted the entire error message above. Not sure what to from here. Any help will be appreciated.

I am not using conda or any other virtual environment. Installed python3 on the raspi directly and now I am directly typing the .py scripts in nano and saving them in a local folder on the computer.
