jupyterlab-desktop: Setting a custom Python environment does not work on first launch

Description

I’m running JupyterLab 3.3.4-2 for the first time and trying to re-use my existing Python 3.10 environment installed via Homebrew but after selecting the Python interpreter and selecting Apply and restart, the dialog simply re-appears.

When starting JupyterLab, this dialog is shown:

There, I select the Python binary from my Python 3.10 installation with jupyterlab 3.4.4 installed and select Apply and restart. JupyterLab closes and re-opens and displays the same dialog again. The message stays the same:

Failed to find a compatible Python environment at the configured path “/Users/michi/Library/jupyterlab-desktop/jlab_server/bin/python”.

So maybe the configured path doesn’t get saved before re-opening the application?

Context

I’m running macOS 12.4 on an Apple M1 Mac. I’ve installed Python with the usual brew install python@3.10 and brew link python@3.10. I’m using a custom Homebrew prefix to workaround an issue in Homebrew.

michi ~$ brew --prefix
/Users/michi/opt/homebrew
michi ~$ sw_vers
ProductName:	macOS
ProductVersion:	12.4
BuildVersion:	21F79
michi ~$ brew --prefix
/Users/michi/opt/homebrew
michi ~$ python3 --version
Python 3.10.5
michi ~$ which python3
/Users/michi/opt/homebrew/bin/python3
michi ~$ python3 -m pip list | grep jupyterlab
jupyterlab           3.4.4
jupyterlab-pygments  0.2.2
jupyterlab-server    2.15.0

(I'm not sure if this helps)

I didn’t find jlab on my $PATH so I used this command instead:

@marc-medley you can get dmg installers from here, and macOS version already has auto-update feature, it can automatically upgrade to latest version released. but that is not your issue here. brew install --cask jupyterlab seems to install the same dmg as well.

JupyterLab Desktop requires a Python environment with jupyterlab (>=3.4.5) Python package. It ships with a bundled installer to create that required environment. Your python installation created using homebrew doesn’t have jupyterlab python package. You should be able to install using python3 -m pip install jupyterlab

Can this be mentioned somewhere in the steps to install. JupyterLab Desktop recognized my python environment only when I installed jupyterlab in it.

ashishmahalka on Feb 11, 2023

closing this issue since it should be fixed with latest version. please create a new issue if needed.

I abandoned it and have just been using the “regular” web interface version, but I’ll revisit it and let you know.

What’s the point of Jupyter Desktop if you need to have a python + jupyterlab environment?

JupyterLab Desktop ships with a Python environment which includes JupyterLab, but as you mention, using JupyterLab from a custom environment currently requires having JupyterLab installed in that environment (I am not a fan of this either). Two points:

to enable extensions per-environment it is currently necessary to have per-environment jupyterlab installation -but there is no reason it should be like that in the future (it just requires someone to help implement wider changes in extension management, which will be possible with JupyterLab 4.0)
if you don’t need per-environment extensions you could just use conda-nb-kernels (or similar kernel discovery tool) which only requires having per-environment ipykernel (or other) installation.

@mbektas who is the main maintainer may have a different opinion based on their in-and-out knowledge of the underlying machinery, but again, I agree that from the UX point we should not require installing JupyterLab in every environment (or if it absolutely has to be done, we should be able to silently install/update it after user’s consent).

Apologies for my stupid question, as I certainly missed or misunderstood key information.

@mbektas I am also encoutering the same “Failed to find a compatible Python environment…” issue when attempting to do a clean install of “JupyterLab.app” such that it uses an existing homebrew installation of Python3. If possible, I am attempting minimize the number of Python installations on my system.

Here is the information that I have related to your questions.

Do you happen to have any spaces in the custom environment path?

No spaces.

/opt/homebrew/bin/python3

Each of the following also produced the same error:

/opt/homebrew/bin/python3.11
/opt/homebrew/Cellar/python@3.10/3.10.9/bin/python3
/opt/homebrew/Cellar/python@3.11/3.11.1/bin/python3.11

Can you check if there are any relevant logs related to server launch in ~/Library/Logs/jupyterlab-desktop/main.log?

… If you use dmg installer, then …

Is there a link somewhere for a JupyterLab dmg installer?? (I was only finding pip instructions, a homebrew formula and a homebrew application cask.)

brew info --cask jupyterlab

# ==> jupyterlab: 3.5.1-1
# https://github.com/jupyterlab/jupyterlab-desktop
# /opt/homebrew/Caskroom/jupyterlab/3.5.1-1 (124B)
# From: https://github.com/Homebrew/homebrew-cask/blob/HEAD/Casks/jupyterlab.rb
# ==> Name
# JupyterLab App
# ==> Description
# Desktop application for JupyterLab
# ==> Artifacts
# JupyterLab.app (App)

I installed JupyterLab.app as a homebrew applicaton cask. The reason being that periodic a brew update; brew upgrade will also keep the .app version updated.

brew install --cask jupyterlab

The homebrew cask desktop application install does put the app in /Applications/JupyterLab.app, as would a .dmg drag & drop install to the Applications folder.

… pythonPath … set to empty string in jupyterlab-desktop-data file (in ~/Library/jupyterlab-desktop/jupyterlab-desktop-data). It will reset Python environment ….

I am working with a clean install such that pythonPath is empty.

"pythonPath":""

Can you manually launch the server from a terminal after activating your custom environment and see if there are any errors? using the command:
python -m jupyterlab --no-browser --expose-app-in-browser --JupyterApp.config_file_name="" --ServerApp.port=8888 --ServerApp.password="" --ServerApp.allow_origin="*" --ContentsManager.allow_hidden=True

Note: python is not (yet) defined on my system. The machine started as a clean install of macOS Ventura 13.1 running on Apple Silicon. Standard Xcode and various commandline tools (homebrew utilities) are installed. This includes python3 (currently pointing to python3.10), python3.9, python3.10, and python3.11

which -a python
# python not found

which -a python3
# /opt/homebrew/bin/python3
# /usr/bin/python3
python3 --version
# Python 3.10.9

which -a python3.11
# /opt/homebrew/bin/python3.11
python3.11 --version
# Python 3.11.1

So, using python3 and python3.11 the following resulted:

python3 -m jupyterlab --no-browser --expose-app-in-browser …
# /opt/homebrew/opt/python@3.10/bin/python3.10: No module named jupyterlab

python3.11 -m jupyterlab --no-browser --expose-app-in-browser …
/opt/homebrew/opt/python@3.11/bin/python3.11: No module named jupyterlab

Should it be somehow possible for JupyterLab.app to use a homebrew python installation?

marc-medley on Jan 17, 2023

@Feuermurmel this should be fixed now with v3.5.1-1. could you test and update the issue?
