Why I can't do 'conda activate <env>' in JupyterLab?

Hi all,

I am using Jupyter lab, I can use conda command such as:

conda list
conda info --envs
pip list

but I cannot use conda activate <env-name> even if I have tried conda init

This is what shows up when I type conda init
no change /home/browni/.julia/conda/3/condabin/conda
no change /home/browni/.julia/conda/3/bin/conda
no change /home/browni/.julia/conda/3/bin/conda-env
no change /home/browni/.julia/conda/3/bin/activate
no change /home/browni/.julia/conda/3/bin/deactivate
no change /home/browni/.julia/conda/3/etc/profile.d/conda.sh
no change /home/browni/.julia/conda/3/etc/fish/conf.d/conda.fish
no change /home/browni/.julia/conda/3/shell/condabin/Conda.psm1
no change /home/browni/.julia/conda/3/shell/condabin/conda-hook.ps1
no change /home/browni/.julia/conda/3/lib/python3.9/site-packages/xontrib/conda.xsh
no change /home/browni/.julia/conda/3/etc/profile.d/conda.csh
no change /home/browni/.bashrc
No action taken.

Note: you may need to restart the kernel to use updated packages.

Then I try to activate the environment:

conda activate lasthrim_env

CommandNotFoundError: Your shell has not been properly configured to use ‘conda activate’.
To initialize your shell, run

** $ conda init <SHELL_NAME>**

Currently supported shells are:
** - bash**
** - fish**
** - tcsh**
** - xonsh**
** - zsh**
** - powershell**

See ‘conda init --help’ for more information and options.

IMPORTANT: You may need to close and restart your shell after running ‘conda init’.

Note: you may need to restart the kernel to use updated packages.

I have restart the notebook, adjust the .bashrc so when I shutdown and restart the conda will be activated.

This conda initialize already in my .bashrc:

# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$('/home/browni/.julia/conda/3/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; then
    eval "$__conda_setup"
else
    if [ -f "/home/browni/.julia/conda/3/etc/profile.d/conda.sh" ]; then
        . "/home/browni/.julia/conda/3/etc/profile.d/conda.sh"
    else
        export PATH="/home/browni/.julia/conda/3/bin:$PATH"
    fi
fi
unset __conda_setup
# <<< conda initialize <<<
