Pyrit: I am not able to run Pyrit code(Automation framework by Microsoft)

I was not able to run Pyrit code that is mentioned in Microsoft documentation.
Error:
PYRIT\PyRIT\doc\demo\1_gandalf.py", line 51, in <module>
from pyrit.chat import AzureOpenAIChat
ModuleNotFoundError: No module named 'pyrit'

I did nothing, just clone the repo mentioned in doc, and try o run, and I got the above error.

Could you please help?
