problem with install

[hmyh1202]

Hello I got error below:

$export PYTHONPATH=/Software/anaconda3/envs/firecaller/lib/python3.6/site-packages/lib/python3.6/site-packages && Software/anaconda3/envs/firecaller/bin/python3 ./FIREcaller
Traceback (most recent call last):
File "/Software/anaconda3/envs/firecaller/lib/python3.6/site-packages/lib/python3.6/site-packages/cooler/sandbox/dask.py", line 10, in
from sparse import COO
ModuleNotFoundError: No module named 'sparse'

During handling of the above exception, another exception occurred:

so I need to install sparse alone

Thank you.
