TypeError: 'float' object cannot be interpreted as an integer

[alyferryhalo]

I tried this command as described in tutorial:

python json2cosm.py -i dancing_man.json -o dancing_man.pdb -r origami_r -t origami_t -l h -m origami_map

And got this traceback:

Traceback (most recent call last):
  File "/Users/alisagorislav/Documents/dna-origami/cosm_scripts-master/json2cosm.py", line 1108, in <module>
    beg - part[2][0]) * k), range(beg, end + HC * k, HC * k),
TypeError: 'float' object cannot be interpreted as an integer

What could be a problem?

Here is a .json file on google disk.

I use macOS Monterey 12.1
