Looks like spacy 2.1 --> 2.2 has changed the way lemmatizer objects are built. See stack-overflow answer for details.
I can update the library to account for this migration. I have a fork that I can create a pull request from. Let me know.
Steps to reproduce the behavior:
Run
"from nlp_architect.pipelines.spacy_bist import SpacyBISTParser"
using spacy 2.2.
**Environment setup: **
- OS (Linux/Mac OS): Linux SLES12
- Python version: 3.6; spacy 2.2
