make build-proto and make test fail after following Getting Start instructions

Description

At the time of this writing, make test fails in the Docker environment after following the getting-started instructions.

Reproduction

docker pull ghcr.io/tri-ml/dgp:master
docker image tag ghcr.io/tri-ml/dgp:master dgp:latest
make docker-start-interactive
# either of the following fail
make build-proto
make test

For example, make test fails with:

root@hostname:/home/dgp# make test
python3 setup.py clean && \
rm -rf build dist && \
find . -name "*.pyc" | xargs rm -f && \
find . -name "__pycache__" | xargs rm -rf
Traceback (most recent call last):
  File "setup.py", line 5, in <module>
    from setuptools import find_packages, setup
ModuleNotFoundError: No module named 'setuptools'
Makefile:33: recipe for target 'clean' failed
make: *** [clean] Error 1

python3 is actually 3.6.9.

root@hostname:/home/dgp# python3
Python 3.6.9 (default, Jun 29 2022, 11:45:57)

but setuptools is installed for 3.7:

root@hostname:/home/dgp# pip show setuptools
Name: setuptools
Version: 63.2.0
Summary: Easily download, build, install, upgrade, and uninstall Python packages
Home-page: https://github.com/pypa/setuptools
Author: Python Packaging Authority
Author-email: [email protected]
License: 
Location: /usr/local/lib/python3.7/dist-packages
Requires: 
Required-by: astroid, grpcio-tools, xarray

Fix

Two solutions: one is to not install Python 3.6 at all so that python3 symlinks to 3.7. Another is to update the Makefile to use python3.7 specifically.
