BrokenProcessPool when running quickstart (M1 Mac) #89

Closed bfhealy closed 5 months ago

bfhealy commented 10 months ago

I'm encountering errors (on an M1 Mac) when working through the quickstart guide.

Here are the lines I ran to install the software within a conda environment with python 3.10:

python /Applications/CPLEX_Studio2211/python/setup.py install
pip install git+https://github.com/nasa/radbelt.git
pip install git+https://github.com/nasa/dorado-scheduling

Note that I installed radbelt like this because the default installation had issues with the M1 arm64 architecture.

After the installation, I cloned this repo and ran: dorado-scheduling examples/6.fits -o examples/6.ecsv

and got these errors:
