Execute conda in subshell script

When running conda activate in a bash script, I came across a similar error message to this.

CommandNotFoundError: Your shell has not been properly configured to use 'conda activate'

With a quick Google search, this thread showed up and has been helpful with several suggestions.

The most voted on and immediate solution was adding this to my bash script.

source ~/anaconda3/etc/profile.d/conda.sh
conda activate my_env

For your use, you’d have to change your Anaconda/conda path and conda environment name.

One other solution includes using this instead.

eval "$(conda shell.bash hook)"
conda active my_env

At first glance, the conda shell.bash hook appears to come out of nowhere. Doing some copy-paste-searching around, this appears to be part of the conda initialization script. In other words, this is the more flexible and generalizable form of the solution above because you don’t have to change or specify where that conda.sh script.

The last solution suggested is calling the script with bash -i to invoke the interactive environment, which loads the ~/.bashrc file. This file presumably has the conda activation script in there.
