I am trying to create a script in jupyter for testing google GEMINI AI model

import google.generativeai as genai
import os

# genai.configure(api_key="API Key")

model = genai.GenerativeModel('gemini-pro')
response = model.generate_content('Please summarise this document: ...')

print(response.text)

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
Input In [2], in <cell line: 6>()
      2 import os
      4 # genai.configure(api_key=os.environ['API_KEY'])
----> 6 model = genai.GenerativeModel('gemini-pro')
      7 response = model.generate_content('Please summarise this document: ...')
      9 print(response.text)

AttributeError: module 'google.generativeai' has no attribute 'GenerativeModel'

Tried:
Re-installing package – python3.11 -m pip install google-generativeai
Checked whether the class named ‘GenerativeModel’ existed in my installed package source code but it didn’t help.

I want a proper response getting returned form GEMINI.

Config:
python- 3.11.7
google-generativeai-0.5.1
