cannot downgrade to pip 9

• Pip version: pip 10.0.0 from /opt/anaconda/lib/python3.6/site-packages/pip (python 3.6)
• Python version: Python 3.6.4 :: Anaconda custom (64-bit)
• Operating system: Distributor ID: Ubuntu Description: Ubuntu 16.04.3 LTS Release: 16.04 Codename: xenial

Description:

trying to install catboost. I suspect it fails due to pip 10.0.0 since I know it works in older pip versions. Trying to downgrade pip fails.

What I’ve run:

python -m pip install pip==9.0.3 --upgrade --force-reinstall

pip 10.0.0 from /opt/anaconda/lib/python3.6/site-packages/pip (python 3.6)

I would expect to get pip 9.0.3 when I do pip --version

I managed to revert pip to 9.0.3 using: sudo pip install --force-reinstall pip==9.0.3
