I want to build a chatbot, how to install the corresponding version of rasa_core and tensorflow?

hey @Bob as a suggestion can you please downgrade your python version to 3.6 as tensorflow is supported for python version less than <3.6

What version of the rasa_core installation?

@Bob have you visited this Installation for rasa nlu and for rasa core Installation
