Is there infer CNV like python library which works for Python 3.7.1 (colab/kaggle) ? (Problem: infercnvpy

There is nice Python lib : pypi.org/project/infercnvpy/
which infers copy number variations from the single-cell RNA seq data.
But it requires Python 3.8 and on free clouds like colab (or kaggle) one has 3.7.1

Question: Is there infer CNV like python library which works for Python 3.7.1 (colab/kaggle) ?

Or there can be other ways round ?
