Hello, i use tljh jupyter hub, and i try add more in jupyter lab python kernels whith conda.  
Whithot envs in bash:

1. `python --version > Python 3.10.10`
2. `conda --version > conda 23.1.0`
3. `conda list` or `pip list` - show many installed packages, i think its packages in base conda env
4. `conda info --envs > base /opt/tljh/user`  
then create anover conda envirement `conda create --name myenv python=3.11 ipykernel ` and install ipykernel,  
then `conda info --envs` shows two evirents:  
`myenv /home/jupyter-adminuser/.conda/envs/myenv`  
`base /opt/tljh/user`

next activate env `conda activate myenv`  
check version python and conda steps 1-3 and wi see:

1. `python --version > Python 3.11.7`
2. `conda --version > conda 23.1.0`
3. `conda list` or `pip list` show count packages small then it was first time,
4. install the JupyterLab Kernel with command `python -m ipykernel install --user --name myenv --display-name "Python (myenv)"`

we see message `Installed kernelspec myenv in /home/jupyter-adminuser/.local/share/jupyter/kernels/myenv`  
deactivate our conda env with command `conda deactivate`, restart server, and go to jupyter netebook, and select Kernel Python (myenv)  
in code cell write and run `!python --version` output: `Python 3.10.10` **why?** _ **its should be Python 3.11.7 not 3.10!** _  
ok, lets check our packages `!pip list` and `!conda list` and i see in conda list `# packages in environment at /opt/tljh/user:` **why?**  
when i open ipython console i see  
`Python 3.11.7 | packaged by conda-forge | (main, Dec 23 2023, 14:43:09) [GCC 12.3.0] Type 'copyright', 'credits' or 'license' for more information IPython 8.19.0 -- An enhanced Interactive Python. Type '?' for help.`  
but when i enter `!python --version`, i see output Python 3.10.10  
**can you please describe and help resolve this problem? how i can create many different kernels? why he create kernel like base conda env?**

why command `!python -V` shows python 3.10?  
I think what i install kernel wrong, but in kernel json all good

problem solved.  
for conda envs need install package `nb_conda_kernels` and `ipykernel` in new env, reload jupyter server and all should works.  
creatink work kernel should see like `conda creane --name new_env python=3.11 nb_conda_kernels ipykernel` when shutdow and up jupyter server

`python -m ipykernel install --user --name myenv --display-name "Python (myenv)"` needs when we use not `conda env` like `venv`, when it should work
