1. please simplify the steps as much as possible so they do not require additional resources to run, such as a private dataset.

• Download repository
• Build from Dockerfile

Possible Fix:

Update the link to download the desired pip version: https://bootstrap.pypa.io/pip/3.6/get-pip.py

Environment:

Hey,

I ran the DockerFile with the updated lines, but a similar error appears when the file runs the command ERROR [12/13] RUN pip install --user -e detectron2_repo.

#15 19.10 ERROR: Package ‘detectron2’ requires a different Python: 3.6.9 not in ‘>=3.7’

executor failed running [/bin/sh -c pip install --user -e detectron2_repo]: exit code: 1

Any suggestions?
