How can I see all installed Python modules in Jupyter Lab (like pip freeze) with Python 3.7 or newer?

I'm looking for a way to get a list of all installed/importable python modules from a within a Jupyterlab notebook.

From the command line, I can get the list by running

py -3 -m pip freeze

(or)

pip freeze

In the Jupyterlab console, running pip freeze returns

The following command must be run outside of the IPython shell:

    $ pip freeze

The Python package manager (pip) can only be used from outside of IPython.
Please reissue the `pip` command in a separate terminal or command prompt.

See the Python documentation for more information on how to install packages:

https://docs.python.org/3/installing/

For older versions of pip, it was possible to import pip and get a list from within a notebook.

The command was

help('modules')

This now gives a warning and returns nothing.

10 year old stackoverflow solutions like How can I get a list of locally installed Python modules? also no longer work.

Is there a proper way of doing this (without using a subprocess hack or running pip as an external program like "!pip")

you can also try

!pip freeze

in your jupyter notebook. Hope it helps you.

Install conda, pip or apt packages — The Littlest JupyterHub v0.1 , Packages / libraries installed in this environment are available to all users on the Log in as an admin user and open a Terminal in your Jupyter Notebook. Conda lets you install new languages (such as new versions of python, node, R, etc) as All new TLJH installs use miniconda 4.7.10, which comes with a Python 3.7� There are a couple of ways you can do that.

Environments, Conda, Pip, aaaaah! | by Dennis Bakhuis, However, using packages that are not as popular, breaking changing can happen, especially when upgrading the package or Python itself. A way� For this reason, it is safer to use python -m pip install, which explicitly specifies the desired Python version (explicit is better than implicit, after all). This is one reason that pip install no longer appears in Python's docs, and experienced Python educators like David Beazley never teach bare pip.

import pip._internal.operations.freeze

This works in Win10 with Python 3.6 & 3.7 (ipython, pip.version: '20.0.1') at least. I took a look at the source code in Lib\site-packages\pip.

Configuring Python Workspace, Being a self-learner of Python, I started to use it as almost all all packages were installed globally, and I often used sudo pip install if there were Code for Python coding, but I use Jupyter Notebook (or Jupyter Lab) run in pyenv install 3.7.6 $ pyenv shell 3.7.6 3.8.1 $ virtualenv .venv --python=python3.7� Hi, I am in a situation where python, in a terminal, finds a module with “import”. In fact, with “print(help(‘modules’)” I see a list of all available modules, and the module in question is listed. However, when running a jupyter notebook, of the proper version of python, I always get “module not found”. One think that I would like to do is to find out exactly where the module

  • Thanks, using "!" works like running pip as any external program. This does work, still I'm wondering if there's a better way to interact with pip. I'm updating the question to make that clearer.
