Version (please complete the following information):

• Desktop or hosted?: Desktop v 1.2.0
• Browser (if hosted) [e.g. chrome, safari]:
• Version [e.g. 0.13.0]:
  Windows 10, running Power Shell or Command (admin or user modes)

Additional context
Same error if the model file is downloaded prior to command execution.
Model file download seems succeeds (directory .models_cache is generated)
It is not obvious to me which file cannot be found
cellxgene explorer works fine (hosted)
