cannot downgrade to pip 9

[chanansh]

• 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
Collecting pip==9.0.3

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

What does python -c "import sys; print(sys.executable)" show? I suspect that your python executable is pointing to a different Python installation than your pip executable...

As this is Linux, doesn't python usually refer to a Python 2 installation?

[chanansh]

it shows /opt/anaconda/bin/python

after sudo conda update -all I was able to get back pip 9 and install catboost.

you should be able to do it with this I just did it on windows based system so please adjust to your OS

python -m pip uninstall pip
python -m ensurepip
python -m pip install -U "pip<10"

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

thanks @littlehera , sudo pip install --force-reinstall pip==9.0.3 just works fine.

Closing since the OP solved his issue.

I manage my problem using @Kobra299 to downgrade from pip 10
