Problem with tensorflow while downloading rasa_core

Hi there ! I’m trying to update the rasa bot source code from a friend of mine but I had a problem when trying to download rasa_core:

(cha_env) C:\Users\antoi\Documents\Programming\Nathalie\Chatbot_RASA_room_reservation>pip install rasa_core
Collecting rasa_core
 Could not find a version that satisfies the requirement tensorflow==1.10.0 (from rasa_core) (from versions: )
No matching distribution found for tensorflow==1.10.0 (from rasa_core)

Do you have any idea ? Is it because of the requirements ?

what is your python version if its 3.7 tensorflow wont install,u need to use python 3.6

You were right.
