Trying to run a program that runs perfectly fine on my local machine, but on AWS I'm getting: TypeError: descriptor '__subclasses__' of 'type' object needs an argument
.
My pip3 isn't upgraded to the latest version, but that shouldn't be causing an issue since I have downloaded the latest version of rasa_core.
Tried re-installing rasa_core using pip3 -u rasa_core, also tried appending the command with sudo. This is the error I get, can someone please help

Can someone please help.
If your python 3.5 is version 3.5.3 or below, I believe upgrading should fix it. See a relevant issue here
From the relevant error in typing:
typing
will only get upgraded with Python if you are on Python 3.5+. Since this issue was fixed in August 2016, I believe any 3.5 release above 3.5.3 should work.
