I'm completely new so apologies if it's something obvious.
Following steps from the video, I created drug_terms with 3 seed words. After about 30 words that I accepted and rejected the suggestions started repeating identically and in the same order while the guy in the video got hundreds of different words.
I tried some of my own examples, but the same problem occurs. I get <30 new examples and after that, they repeat.
The same thing happened with sense2vec.teach in the food video.
