  • Run the command:
·         pip install jupyter

3. Install aisetup:

  • In the Command Prompt (Windows) or Terminal (Mac/Linux)
  • Run the command:
·         pip install aisetup

Start Jupyter Notebook:

·         Run the command:

·         jupyter notebook

in Command Prompt or Terminal.

Alternative: Start Jupyter Lab:

·         Jupyter lab has some extra features, like a file browser that makes it easier to view and upload files.

·         Run the command:

·         jupyter lab

in Command Prompt or Terminal.

Getting API Keys

Once you have installed Anaconda and started up a Jupyter notebook, you can experiment with the OpenWeather and OpenAI APIs! The steps below will show you how to get your own API key for each service.

For each API, you will need to create an account, then create an API key.

OpenWeather

1.       Create an account using the OpenWeatherMap.org sign up page.

    • You must be 16 or over, and agree to the terms of service.


2.       Click on your account name in the top right corner, then "My API keys"



3.       Copy the API key that has been generated for you already.



You're done! You can now use this API key in your code.

OpenAI

OpenAI manages API keys through the OpenAI Platform, which is separate from ChatGPT. You will need to create an OpenAI Platform account even if you already have one for ChatGPT.
