I've installed the Anaconda2-5.1.0-Linux-x86_64 on Ubuntu 16.04 LTS, and when I run conda list I see that the matplotlib version should be 2.1.2. But when I run python I get that the version is 2.0.2 :
$ python
Python 2.7.14 |Anaconda, Inc.| (default, Dec 7 2017, 17:05:42)
[GCC 7.2.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import matplotlib
>>> matplotlib.__version__
'2.0.2'
Why the python package does point on the matplotlib version from Anaconda?

It's very strange. I have Python3.10.3 in an activated conda environment:
python
gives
Python 3.10.4 (main, Mar 31 2022, 03:38:35) [Clang 12.0.0 ] on darwin
Type "help", "copyright", "credits" or "license" for more information.
I can install packages but then the version of the Python in the environment changes to 3.9.12 ? Example:
python
gives
Python 3.9.12 (main, Apr 5 2022, 01:53:17)
[Clang 12.0.0 ] :: Anaconda, Inc. on darwin
Type "help", "copyright", "credits" or "license" for more information.
Typically, I want to install pytorch and following the installation, I'll have the downgraded version of Python available if I run "python".
I have pyenv installed and everything works pretty well except for one aspect: when I run the command python3.9, my system still points to my system's version of python (3.9.13). However, I would like to make it point to my pyenv installed version when running python3.9:
❯ pyenv versions
system
3.7.10
3.8.10
* 3.9.5 (set by /Users/username/.python-version)
❯ python3
Python 3.9.5 (default, Jul 7 2022, 20:35:58)
[Clang 13.1.6 (clang-1316.0.21.2.5)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> exit()
❯ python3.9
Python 3.9.13 (main, May 24 2022, 21:13:51)
[Clang 13.1.6 (clang-1316.0.21.2)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>>
❯ python3.9 --version
Python 3.9.13
❯ python3 --version
Python 3.9.5
Note that the issue occurs just when running python3.9, not python3.
What's wrong in my configuration?
Before installing anaconda, I have my own python configurations:
$ python
Python 3.5.2 (default, Nov 23 2017, 16:37:01)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
...
After installing anaconda, however, without creating a new environment, my default environment is still changed:
$ python
Python 3.7.0 (default, Jun 28 2018, 13:15:42)
[GCC 7.2.0] :: Anaconda, Inc. on linux
Type "help", "copyright", "credits" or "license" for more information.
...
How could I use my own 3.5.2 python environment when not activating the anaconda python environment ?

The program 'python' is currently not installed. You can install it by typing:
apt-get install python-minimal
even when i install python-minimal it doesn work.
please suggest..
Create a symbolic link /usr/bin/python pointing to either /usr/bin/python2 or /usr/bin/python3
