ImportError: cannot import name 'ssl' from 'urllib3.util.ssl_'

[Þórunn Arnardóttir]

When I tried to run the following:
python3 src/main.py train --model-path-base models/ --train-path data/gamalt_icepahc/train_random.clean --dev-path data/gamalt_icepahc/dev_random.clean --predict-tags --use-bert

An error arose:

Processing trees for training...
Constructing vocabularies...
Initializing model...
