Environment for scArches loading/application

[chartl]

It would be useful (either here or at the Zenodo project) to include the appropriate environment for applying the scArches model to new data. Updates to pytorch, scArches, numba, umap-tool, and scanpy all lead to conflicts for loading, applying, or analyzing new data during or after integration with the core set. After much trial and error, the following environment appears to work:

name: GBmap_env

channels:
  - conda-forge
  - bioconda

dependencies:
  - python==3.8
  - pip
  - pip:
    - torch==1.6.0
    - scvi-tools==0.8.1
    - scArches==0.3.0
    - umap-learn==0.4.6
    - numba==0.52.0
    - leidenalg
    - seaborn
    - jupyter
