Im trying to use this instead of the original plutus.

Traceback (most recent call last):
File "/Users/xxxxx/plutushybrid/plutushybrid.py", line 3, in
import mnemonic
ModuleNotFoundError: No module named 'mnemonic'

when i run:

xxxxx@-MacBook-Pro ~ % pip3 install mnemonic
Requirement already satisfied: mnemonic in /usr/local/lib/python3.9/site-packages (0.19)

xxxxx@-MacBook-Pro ~ % python3 plutushybrid/plutushybrid.py
Traceback (most recent call last):
