Stanza pipeline
If gatenlp has been installed with the stanza extra (pip install gatenlp[stanza] or pip install gatenlp[all]) you can run a Stanford Stanza pipeline on a document and get the result as gatenlp annotations.
from gatenlp import Document
from gatenlp.lib_stanza import AnnStanza
import stanza
print("Stanza version:", stanza.__version__)
Stanza version: 1.3.0
# In order to use the English pipeline with stanza, the model has to get downloaded first
stanza.download('en')
