Issues with multithreading when running on Mac #7

Closed hzovaro closed 1 year ago

hzovaro commented 1 year ago

When running the following on my local machine (either with python script.py or %run script.py in ipython):

import os
from spaxelsleuth import load_user_config
load_user_config("/Users/u5708159/Desktop/spaxelsleuth_test/.myconfig.json")
from spaxelsleuth.loaddata.sami import make_sami_metadata_df
nthreads = 4

# Create the DataFrames
make_sami_metadata_df(recompute_continuum_SNRs=True, nthreads=nthreads)

I get the following output (after interrupting):

but if I copy & paste the code into ipython it works.

Steps to reproduce:

from spaxelsleuth import load_user_config
load_user_config("/Users/u5708159/Desktop/spaxelsleuth_test/.myconfig.json")
from spaxelsleuth.loaddata.sami import make_sami_metadata_df
nthreads = 4

# Create the DataFrames
make_sami_metadata_df(recompute_continuum_SNRs=True, nthreads=nthreads)

Error occurred.

OK, so I fixed the problem - on my Mac, the error goes away when the script is within a if __name__ == "__main__" block.
