Hi there! I am having trouble running the Spacy nodes from Redfield NLP extensions due to error

[rmonterosapri]

Hi Knime community! I am wondering if you could help solve an error I am getting when trying to use the Spacy nodes from Redfield NLP extension. I am getting the following erros when tryin to run the Spacy Model Selector Node.

Hello @rmonterosapri

Could you please provide a more detailed log file? To do this try to configure or run the Spacy Model Selector node, once it fails to run please go to View → Open KNIME Log, and there please find the line with a full stack trace that only refers to this node.

Hi @Artem ! Thanks a lot! I think this is what you are referring right? Many thanks!:

The message is not full, please paste it as a text in the message using a preformatted text mode for better readability.

But so far, I can see that you have problems with Python environment. Please check the settings of Redfield NLP nodes. Probably the best option would be to select the Bundled environment.

Thanks @Artem here’s the text:

Additionally, I am not able to configure the Redfield extension in my preferences:

It seems more like a Python issue to me. Perhaps you can try re-installing Redfield NLP nodes extension, since it should provide a bundled Python environment, so user does not have to bother about Python installation.

I am not sure, but it might also be connected to the Windows specific issue that refers to too long file paths. Perhaps this solution might work for you as well:
https://docs.knime.com/latest/python_installation_guide/index.html?pk_vid=4539cfbff82e114217058165514cd8b3#windows-issues

And could you please specify what version of Knime are you using?
