Using the OpenAI API Library 1 - Installing JupyterLab

Published on


In this tutorial, we will install the necessary tools and run a simple openai-cookbook notebook to learn how to use the openai API.


  • To use the OpenAI API, get an OpenAI API key from the OpenAI site. You need to create an account and enter your credit card information.
  • Add OPENAI_API_KEY to the OS environment variable. To add it in Windows OS, go to windows menu > Settings > System > About > "Advanced System Settings" popup, click Environment Variables button, Click the add button on System Variables, enter OPENAI_API_KEY as the variable name and your API key as the variable value.

Using Jupyter Notebook on PC


  • JupyterLab is the next generation web-based interactive development environment that replaces Jupyter Notebook.
  • Miniconda - a minimalized version of a package manager that allows you to manage virtual environments and install packages in Python (other languages besides Python?!)


Commands for creating virtual environments when using Miniconda, allowing you to run multiple versions of Python in separate environments by creating different environments.

  • conda create -n "virtual-env-name" python=3.8 - creates a virtual environment with a specific name with a specific version of Python.
  • conda info -e - get a list of virtual environments
  • conda activate "virtual-env-name" - activates the virtual environment with the specified name
  • conda deactivate - deactivates(exit) a virtual environment
  • conda remove -n "virtual-env-name" --all - remove a virtual environment with the specified name

INstalling and running JupyterLab

Here is the installation sequence

  1. install Miniconda (include Python in the installation file)
  • On Windows, after completing the installation with the installation file, "Anaconda Powershell Prompt (miniconda3)" is created in the menu. Press it to run it.
  • Check if the OPENAI_API_KEY environment variable is set correctly with the command echo $Env:OPENAI_API_KEY
  1. conda create -n openai python=3.8 - Create a virtual environment with the name "openai" in python 3.8 version.
  2. conda activate openai - Activate the virtual environment created
  3. pip install jupyterlab - Install JupyterLab
  4. pip install tenacity tiktoken openai "openai[datalib]" - Install the OpenAI API related libraries
  5. jupyter lab . - Run JupyterLab with the current directory (.) as the root of the notebook, and automatically open the browser to display the JupyterLab webpage.
