Not able to install MarianMTModel, MarianTokenizer

I am not able to install MarianMT from transformers.

Error:

ImportError Traceback (most recent call last)

----> 1 from transformers import MarianMTModel, MarianTokenizer

ImportError: cannot import name ‘MarianMTModel’ from ‘transformers’ (/home/ravneet/.local/lib/python3.7/site-packages/transformers/init.py)
