The KeyError: 'weight'

[biosciences]

When I try to run this command:
correct-cnv -H patient_hg38_contact_map.mcool::resolutions/100000
--cnv-file patient_hg38_contact_map_100kb.CNV-seg.bedGraph --nproc 4 -f

It return such error:
Traceback (most recent call last):
File "/home/user1/var/opt/mambaforge/envs/neoloop/lib/python3.10/site-packages/pandas/core/indexes/base.py", line 3791, in get_loc

KeyError: 'weight'

It seems to find certain metadata, including normalization vectors. If these vectors are absent or not recognized, it could result in a KeyError: 'weight' because the tool cannot find the expected data.

I used JuiceBox Tools to generate HiC data by following the instructions: https://protect-au.mimecast.com/s/0EM_CjZ1N7iYvJw2BhWhDsz?domain=dovetail-capture.readthedocs.io, and use below command to convert the hic file:
hic2cool patient_hg38_contact_map.hic patient_170052_18_hg38_contact_map.mcool

Hi, you may need to run cooler balance before you run correct-cnv. Please also refer to this similar issue #8 for more explanation.
