Activating conda environment from bash script - bash

Question

I would like to change my conda environment from a bash script.
I want to run bash script_yxz, where 'script_xyz' is like:
#!/bin/bash
conda activate my_env
and switch to my_env.
This already works if I run source script_yxz.
But I have the problem that I am not able to 'source' on remote machines with 'sshpass'.
To better understand my purposes, my goal is to run on my terminal
sshpass -p "password" ssh -o user#server "bash script_xyz"
and changing the environment on the server.
This is why I need to use bash instead of source.
I have read a lot of solutions on various forums but none of them works.

Answer 1

seems like the conda script is not imported by default so this should fix it
source ~/anaconda3/etc/profile.d/conda.sh
conda activate <env>

Answer 2

#!/bin/bash
eval "$(conda shell.bash hook)"
source ~/anaconda3/etc/profile.d/conda.sh
conda create -n testing python=3.10 -y
conda activate testing
python --version
#output

Answer 3

You can use bash,zsh or any shell aliases for this purposes. You just add
alias my_conda='source /home/$USER/anaconda3/bin/activate && conda activate MyPy38'
line into the .bashrc,.zshrc or .any_other_shell_rc.
"N.B. My environment name is MyPy38". So,replace it according name as well as the path /home/$USER/anaconda3.
Also you can create separate file for aliases. Just create a file called .bash_aliases and add
if [ -f ~/.bash_aliases ]; then
. ~/.bash_aliases
fi
lines to .bashrc,.zshrc or .any_other_shell_rc and keep the command
alias my_conda='source /home/$USER/anaconda3/bin/activate && conda activate MyPy38'
into the .bash_aliases. Now, source ~/.zshrc ~/.bashrc or just close and open a new terminal. Run the command my_conda and BOOM!
Also, you can add some other aliases for jupyter-notebook jupyter-lab spyder etc. like
# Just activate my conda
alias my_conda='source /home/$USER/anaconda3/bin/activate && conda activate MyPy38'
# Open Jupyter Notebook in my Env
alias my_jupn='source /home/$USER/anaconda3/bin/activate && conda activate MyPy38 && jupyter-notebook'
# Open Jupyter Lab in my Env
alias my_jupl='source /home/$USER/anaconda3/bin/activate && conda activate MyPy38 && jupyter-lab'
# Open Spyder in my Env
alias my_spyder='source /home/$USER/anaconda3/bin/activate && conda activate MyPy38 && spyder'
To confirm active environment name python code
import sys
print(sys.executable)
