Importerror: cannot import name 'pegasusforconditionalgeneration' from 'transformers'

I tried the following code:

import torch
from transformers import PegasusForConditionalGeneration, PegasusTokenizer

But it gives me the following output:

2022-01-31 11:12:51.303973: I tensorflow/stream_executor/platform/default/dso_loader.cc:44] Successfully opened dynamic library cudart64_100.dll
Traceback (most recent call last):
  File "text_paraphraser.py", line 20, in <module>
    from transformers import PegasusForConditionalGeneration, PegasusTokenizer
ImportError: cannot import name 'PegasusForConditionalGeneration' from 'transformers' (E:\Programming\envs\ANNA\lib\site-packages\transformers\__init__.py)

This is all in a Anaconda Prompt in an environmenf it that helps.

What I have tried:

Following multiple tutorials from multiple places, i thought something was wrong with how i was using the Pegasus transformer but seems that it was actually at the import step everything went sideways.
