How to upgrade to latest sympy 1.10.1?

Product Help Anaconda & Miniconda

I just installed conda on Linux ubuntu. All went OK. But it comes with sympy 1.9 while according to conda own web site, the latest is 1.10.1

https://anaconda.org/anaconda/sympy

I have this problem each time with conda. How to update a package. Nothing I tried works. After each attempt, I check sympy version and it still says 1.9. This is how I check

>which python
/home/me/anaconda3/bin/python
>python
Python 3.9.7 (default, Sep 16 2021, 13:09:58)
[GCC 7.5.0] :: Anaconda, Inc. on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import sympy
>>> sympy.__version__
'1.9'
>>>

Also conda search sympy shows it is there

.....
sympy                            1.9  py37h06a4308_0  pkgs/main
sympy                            1.9  py38h06a4308_0  pkgs/main
sympy                            1.9  py39h06a4308_0  pkgs/main
sympy                         1.10.1 py310h06a4308_0  pkgs/main
sympy                         1.10.1  py37h06a4308_0  pkgs/main
sympy                         1.10.1  py38h06a4308_0  pkgs/main
sympy                         1.10.1  py39h06a4308_0  pkgs/main

These are some of my attempts to upgrade

conda install -c anaconda sympy
conda install sympy=1.10.1
conda update sympy
conda install --name base sympy=1.10.1

None of the above changed the version of sympy. It is still at 1.9. For an example

(base) >conda update sympy
Collecting package metadata (current_repodata.json): done
Solving environment: done

# All requested packages already installed.

(base) >python
Python 3.9.7 (default, Sep 16 2021, 13:09:58)
[GCC 7.5.0] :: Anaconda, Inc. on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import sympy
>>> sympy.__version__
'1.9'
>>>

What is the correct way to update my conda installation to use latest sympy?

Thanks

The base environment specifies sympy as 1.9, updating it would break the Anaconda meta package dependnecies.

Create a new environment and then activate that environment:

conda create -n my_sympy_env sympy=1.10.1
conda activate my_sympy_env 
python
>>> import sympy
>>> sympy.__version__
