I'm trying to import a loom file that I created using Seurat and loomR from 10X data, and I keep getting the same error.

Here is my code:

import scanpy as sc import loompy print(loompy.__version__) ## 3.0.6 adata = sc.read_loom('myloomfile.loom')

Here is the error message I get:

Traceback (most recent call last):

Any idea what's going on here?

Thanks in advance!
