PyYAML 'load()' Missing 'Loader' Argument Error: Solution and Explanation

This error occurs because the 'load()' method of the PyYAML library requires a 'Loader' argument. To fix this error, you can add the 'Loader' argument to the 'load()' method call, like this:

config = yaml.load(stream, Loader=yaml.FullLoader)

This will use the 'FullLoader' class to load the YAML file.
