mismatch with python version

Question

I'm confused with the python version I'm using (under Ubuntu):

I'm using pycharm. In pycharm I'm using python 3.6.8 (checked with pycharm terminal python --version)

When I'm working from linux terminal (not pycharm terminal) and I'm checking the version I'm getting:

3.7.6

I checked which python versions I'm using:

sudo update-alternatives --config python
* 2 /usr/local/bin/python 3.6 0 manual mode

when checking:

python which:
/home/userA/miniconda3/bin/python

1. Why the terminal shows 3.7.6 version while I set the 3.6 version ?

2. How can I fix it ?

Answer 1

You have installed anaconda python version for the user instead of globally. You can try to rectify this by uninstalling miniconda3 on this user. Or using virtual env created from your desired python version.

This can be achieved by using running following command with absolute path of your desired python library

/usr/local/bin/python -m venv <dir_name>

Answer 2

Print python version from linux command line with

python -c 'import sys; print(".".join(map(str, sys.version_info[:3])))'
