Problem using prodigy sense2vec.teach


when trying to create vector with the following command:

prodigy sense2vec.teach s2v_software_terms ./assets/RC_2006-11 --seeds "windows server, windows 10, ios 12, android 12, appache kafka 1"

I get the following error:

ValueError: Can't read file: assets/RC_2006-11/strings.json

I wonder why it is trying to open a file called strings.json? Maybe that is the problem. But why?

Thank you for responding soon, so we are able to continue our work.

Hi there!

When I look at the recipe definition then I can confirm that the second argument is referring to the path to pretrained sense2vec vectors. Did you use one of the pre-trained vector files found here? If I recall correctly, the strings.json is metadata that's packaged with the vectors.

Note, the sense2vec.teach recipe won't create vectors. Rather, it will create a terminology list by leveraging the sense2vec vectors.


thank you for responding. I used also reddit data, but not the one from your link. The source was mentioned in some tutorial. So does the data has to be of a certain structure inside? Can I only use the files you linked to?


You need to point to pre-trained sense2vec vectors which come in a predefined format. You can train these yourself if you want to, but I would generally advise using the ones that the project provides.

Thank you, now it works.
