Jupyterlab

Jupyterlab and terminal

Change virtual environment

Install venv:

sudo apt-get install python3-venv

Create environment:

python3 -m venv myenv --system-site-packages

Activate it:

source myenv/bin/activate

Note that the --system-site-packages flag allows the python packages we installed by default to remain accessible in the virtual environment. It’s best to use this flag if you’re doing this on AI Platform Notebooks so that you keep all the pre-baked goodness.

Install jupyterlab:

pip install jupyterlab

Register this env with jupyter lab. It’ll now show up in the launcher & kernels list once you refresh the page.

python -m ipykernel  install --user --name=myenv
