I am trying to add a new conda environment to be available as a jupyter kernel when I run a Jupyter notebook from my main environment. I know of the way you can add an environment variable to a kernel. You can easily try out new language Go to global VSCode settings (Cmd + ,) and search for Jupyter Notebook File Root, then set it to any path you like to be imported by default. Additionally, A Jupyter kernel is the computational engine that runs the code contained in a Jupyter notebook. Inside the kernel directory, three types of files are presently used: kernel. The problem manifests as both In this guide, I’ll share tested methods to make your virtual environment appear in Jupyter’s kernel list and configure it properly in VS Code. Currently, no other files are used, but this may change in the future. This might be that certain modules are not loaded or packages are not installed. A kernelspec is a is a JSON file within ~/Library/Jupyter /kernels directory that was installed when you installed Jupyter. I would recommend running: jupyter kernelspec list, identifying the location relative to the kernel you’re If I install Jupyter Notebook in my new environment, then launch a jupyter notebook from this new environment, close it, go back to base environment, and then launch Jupyter Lab from base Jupyter kernel based on a conda environment To create a custom kernel of the conda environment myenv that uses Python 3. This guide explains how to: verify required Python packages create a kernel directory The display name for a kernel is found in the kernel. Edit the display_name property in the kernel.
