Unable to load the content of the .loom file into an interactive session of python

Hello velocyto team,

While loading the content of the loom file into an interactive session of python I get the following error-

Python 3.7.7 (default, Mar 26 2020, 15:48:22) [GCC 7.3.0] :: Anaconda, Inc. on linux Type "help", "copyright", "credits" or "license" for more information.

import velocyto as vcy vlm = vcy.VelocytoLoom("/home/eramamur/shi_kb_indexes/loompy/kallisto/IN46.loom") Traceback (most recent call last): File "/home/eramamur/bin/miniconda3/envs/velocyto-r2/lib/python3.7/site-packages/loompy/layer_manager.py", line 81, in getattr vals = self.dict["storage"][name] KeyError: 'ambiguous'

During handling of the above exception, another exception occurred:

Traceback (most recent call last): File "", line 1, in File "/home/eramamur/bin/miniconda3/envs/velocyto-r2/lib/python3.7/site-packages/velocyto/analysis.py", line 61, in init self.A = ds.layer["ambiguous"][:, :] File "/home/eramamur/bin/miniconda3/envs/velocyto-r2/lib/python3.7/site-packages/loompy/layer_manager.py", line 71, in getitem return self.getattr(thing) File "/home/eramamur/bin/miniconda3/envs/velocyto-r2/lib/python3.7/site-packages/loompy/layer_manager.py", line 87, in getattr raise AttributeError(f"'{type(self)}' object has no attribute '{name}'") AttributeError: '<class 'loompy.layer_manager.LayerManager'>' object has no attribute 'ambiguous'

I would appreciate your help with fixing this issue. Thank you so much for your help!
