boto3 installed yet getting ModuleNotFoundError

In an AWS Cloud9 IDE, when running

sudo pip install boto3 && sudo pip3 install --upgrade awscli && python3 permissions.py

the first two parts work fine and then in the last part I get

Traceback (most recent call last):

File "permissions.py", line 4, in

import boto3

ModuleNotFoundError: No module named 'boto3'

The permissions.py file has at the top

import boto3

If I run pip freeze can see that boto3 is installed
