RuntimeError: cannot cache function 'rdist': no locator available

[Marwansha]

i came across this error in the SCEQTL_PIPELINE_QC step for the demultiplexing and doublet detection, i found out that this bugg is correlated to Numba ,

RuntimeError: cannot cache function 'rdist': no locator available for file '/opt/conda/envs/py36/lib/python3.6/site-packages/umap/layouts.py'. (scrublet job) 
RuntimeError: cannot cache function 'sparse_mean_var_minor_axis': no locator available for file '/opt/conda/envs/py36/lib/python3.6/site-packages/scanpy/preprocessing/_utils.py' (doublet detection job)

one of the simple Workarounds from this issue seem to be:
Add zip_safe=False to the setup.py of the packages using Numba caching but for that its cannot be done without permission to edit the python files

kindly check those
