How to Run `conda activate` in a Shell Script

What if we try to run conda activate in a bash or shell script?

conda activate <env_name>

We might encounter the following error:

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'.

We can run conda activate in a bash/shell script if we first run eval "$(conda shell.bash hook)".

eval "$(conda shell.bash hook)"
conda activate <env_name>

eval allows us to execute a command from a string argument.

Run conda shell.bash hook in terminal to get an idea of the conda init script that we’re executing.
