Using Jupyter Lab in a Virtual Environment

If you want to use Jupyter Lab in a virtual environment so that only selected packages are available in the scope of the notebook.

To do this we have to add a new kernel for the virtual environment in the list of kernels available for the Jupyter Lab.

Create a virtual environment

Open the directory where you want to create your project.

Open a Terminal and navigate to the same directory and run the following commands to create a virtual environment.

1

python -m venv venv

Activat

Now you have our virtual environment, activate it.

1

venv\Scripts\activate

Install jupyter kernel

Install jupyter kernel for the virtual environment using the following command

1

ipython kernel install --user --name=venv

Select the installed kernel when you want to use jupyter notebook in this virtual environment

Run the - jupyter lab - command in the terminal the Jupyter environment will open up.

Click on the venv kernel you just created.

Install modules

You can install modules in 2 ways:

pip install

Use pip install and install each module one at the time

1

pip3 install "module name"

requirements.txt

You can create an requirements.txt file and list the modules in that file, then install all the modules:

1

pip3 install -r requirements.txt

Uninstall kernel

After you are done with the project and no longer need the kernel you can uninstall it by running the following code:

1

jupyter-kernelspec uninstall venv

Python 3.7

Steps

  1. Download Python 7 from: https://www.python.org/downloads/release/python-379/

Download the

  1. Place the unzipede file in the folder where you are creating the venv

  2. Create the virtuel enverioment with the command:

    virtualenv -p .\python-3.7.9\python.exe powerbi

  3. Check you Python versin with:

    python -V
