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.
