| My Jupyter and Conda setup | 2022-02-02 | post |
These are my notes to myseld about how to setup my jupyter environments because I always forget
Use micromamba instead of conda
Mamba is hugely faster than conda. Use minimamba installed with brew.
Put this in the ~/.condarc (which mamba obeys):
channel_priority: strict
channels:
- conda-forge
Jupyter environmnet
Create a jupyter_env.yaml file (so that you can tear it down and rebuild it when everything explodes)
Create env from file: mamba env create -f file.yaml
Remove env by name: mamba env remove -y -n envname
Export only manually installed packages to file: mamba env export --from-history
name: jupyter
channels:
- conda-forge
dependencies:
- python=3.11
- jupyterlab
- nb_conda_kernels # This makes conda envs visible to jupyterlab
- jupyterlab_widgets # Makes ipywidgets work in jupyterlab
Notes:
(making mamba kernels visible)[https://github.com/Anaconda-Platform/nb_conda_kernels]
(making ipywidgets work)[https://ipywidgets.readthedocs.io/en/latest/user_install.html#installing-the-jupyterlab-extension]
Can get a env yaml with conda env export --from-history
Child environments
To make other environments visible to the jupyter lab instance and make ipqidgets work (i.e for tqdm progress bars) you need two extra packags:
name: child
channels:
- conda-forge
dependencies:
- python=3.11
- ipywidgets # The child to jupyterlab_widgets
- ipykernel # The child to nb_conda_kernels
