-
Create a Python virtual environment using the
venvmodule by running:python -m venv --system-site-packages NAMEReplace NAME with the name you want to give to your virtual environment.
Note
The command, above, creates a virtual environment that has access to Lambda Stack packages and packages installed from Ubuntu repositories.
To create a virtual environment that doesn’t have access to Lambda Stack and Ubuntu packages, omit the
--system-site-packagesoption. -
Activate the virtual environment by running:
. NAME/bin/activateReplace NAME with the name you gave your virtual environment in the previous step.
Python packages you install in your virtual environment are isolated from the base environment and other virtual environments.
Note
Locally installed packages can conflict with packages installed in virtual environments. For this reason, it’s recommended to uninstall locally installed packages by running:
To uninstall packages installed locally for your user only, run:
pip uninstall -y $(pip -v list | grep ${HOME}/.local | awk '{printf "%s ", $1}')
To uninstall packages installed locally, system-wide (for all users), run:
sudo pip uninstall -y $(pip -v list | grep /usr/local | awk '{printf "%s ", $1}')
Warning
Don’t run the above uninstall commands on Lambda GPU Cloud on-demand instances!
The above uninstall commands remove all locally installed packages and, on on-demand instances, break programs including pip and JupyterLab.
