FileNotFoundError for Old French lemmatizer

[kylepjohnson]

Describe the bug When calling the default Old French NLP models (stanfordnlp.Pipeline(lang="fro")), then following error arises:

FileNotFoundError: [Errno 2] No such file or directory: '/Users/kyle.p.johnson/stanfordnlp_resources/fro_srcmf_models/fro_srcmf_lemmatizer.pt'

To Reproduce

See gist here for commands and full traceback: https://gist.github.com/kylepjohnson/d40215b380be4b050b5cc1ceac09e369

Expected behavior Expect the Pipeline object to become instantiated.

Environment (please complete the following information):

• OS: MacOS Mojave 10.14.6
• Python version: Python 3.7.5 from pyenv
• StanfordNLP version: 0.2.0

Additional context I've tried several other languages (Ancient Greek grc and Latin lat) and the Pipeline works fine.

We don't seem to officially support fro, though I can see a models download file for it. You should just set lemma_use_identity to True in your application.

Thank you, I will try this out and come back for help, if needed.
