Please, use proper tags when post code, traceback, output, etc. This time I have added tags for you.
See BBcode help for more info.

Please, post the entire traceback that you get. We need to see the whole thing. Do not just give us the last line.
Take a time to read What to include in a post

Try to install smbus

Output:
sudo apt-get install python3-smbus

Or perhaps install it from pypi

Output:
python3.7 -m pip install smbus

Try to install smbus

Output:
sudo apt-get install python3-smbus

Output:
python3.7 -m pip install smbus

It's already installed.

Solved! I changed the portnumber from 0 to 1

Output:
smbus.SMBUS(1)
