After you've updated the joblib import (which you've done), it's easiest to just retrain the model, which can be done with these lines. Either run it as a script or just run it directly in python interactive shell.

from talon.signature import EXTRACTOR_FILENAME, EXTRACTOR_DATA
from talon.signature.learning.classifier import train, init
train(init(), EXTRACTOR_DATA, EXTRACTOR_FILENAME)

There are a bunch of PRs to fix this like #219, hopefully one will be approved at some point.
