an Example Environment

Info

To help demonstrate the various concepts, lets create the following environment:

Code Block
[] cd /project/<project-name>/<username>/conda
[]$ module purge
[]$ module load miniconda3/24.3.0
[]$ conda create -p py_conda_pip_env python=3.12
[]$ conda activate /cluster/medbow/project/<project-name>/<username>/conda/py_conda_pip_env
(/cluster/medbow/project/<project-name>/<username>/conda/py_conda_pip_env) []$ python --version
Python 3.12.4
(/cluster/medbow/project/<project-name>/<username>/conda/py_conda_pip_env) []$ which python
/cluster/medbow/project/<project-name>/<username>/conda/py_conda_pip_env/bin/python
# Create a self contined environment i.e don't install anything into the local home folder.
(/cluster/medbow/project/<project-name>/<username>/conda/py_conda_pip_env) []$ export PYTHONUSERBASE=$CONDA_PREFIX
# Use conda to install: numpy
(/cluster/medbow/project/<project-name>/<username>/conda/py_conda_pip_env) []$ conda install numpy
# Use pip to install: nltk
# has dependencies: click, joblib, regex and tqdm
(/cluster/medbow/project/<project-name>/<username>/conda/py_conda_pip_env) []$ pip install nltk

What is Installed? conda list

Info

The conda list command will provide details of all packages as well as conda environment libraries:

The pip list command will only list the explicitly installed pip python packages.

Look at the Installer column to identify what was installed via conda install, pip install, by default.
