Invalid NLP models directory

Hello, I am trying to upload pdf files to the document store and have been trying to use entities, linker rdf extractors. However, I get the following error message:
Invalid NLP models directory /root/stardog-7.3.0
The manual says "BITES has the following built-in RDF extractors". In my case when I use tika and text it works. However, when trying to use entities, linker and dictionary it gives the above error.

Please also note I am currently running Stardog on Linux.

did you deploy the BITES extractor from here: GitHub - stardog-union/bites-corenlp: CoreNLP extractors for Stardog

No, I didn't. Thank you this solves my issue!

Good to hear. I would check out the blog post if you haven't seen it yet: Entity Extraction & Linking - Tutorial | Stardog

Let us know if you have any more questions.
Best,
Jess
