On my development VM (CentOS) I switched from base python and JupyterLab (web version) to miniconda and JupyterLab (web version). Now I’m struggling to be able to switch to different environments.
-
I Installed miniconda
-
I uninstalled the original Jupyter installation with:
/usr/bin/python36 -m pip uninstall -y jupyter jupyter_core jupyter-client jupyter-console jupyterlab_pygments qtconsole notebook nbconvert nbformat nbclassic nbclient jupyterlab-widgets jupyter-events jupyter-server jupyter-server-terminals
- Purged ~/.jupyter/
- Installed jupyter on miniconda with:
conda install -c conda-forge notebook - Installed nb_conda_kernels to manage conda environments from jupyter with:
conda install -c conda-forge nb_conda_kernels - Created a test env with ‘conda create --name test_1’
This environment shows up with conda env list but even after restarting JupyterLab, the only two options I have in the Kernel selector are:
Python 3 (ipykernel)python [conda env:root]*
no test_1 environment
On Start up nb_conda_kernels tells me it found only 1 Kernel
Also on a sidenote, the extension manager still shows some old extensions from the Old Installation, so it seems some stuff got moved over. I used jupyter --paths to find and delete remnants of these old extensions, but they still show up in the extension manager.
