$ deptree --help usage: deptree [-h] [--version] [-r] [-f] [project [project ...]] Display installed Python projects as a tree of dependencies positional arguments: project name of project whose dependencies (or dependents) to show optional arguments: -h, --help show this help message and exit --version show program's version number and exit -r, --reverse show dependent projects instead of dependencies -f, --flat show flat list instead of tree

For better comfort, use as a single-file isolated zipapp:
For example:
$ python -m pip install --target ./deptree/ deptree $ python -m zipapp --python '/usr/bin/env python' --main 'deptree.cli:main' ./deptree/ $ mv ./deptree.pyz ~/.local/bin/deptree
This way the tool can be used in virtual environments without installing it in the virtual environments. The tool can then see the projects installed in the virtual environment but without seeing itself.
