[FIXED] Similarity between two lists of documents

Issue

I need to find the similarity between two lists of the short texts in Python. Texts can be 1-4 word long. The length of the lists can be 10K each. So, I need to effectively calculate 10K*10K=100M similarity scores. I didn't find how to do this effectively in spaCy. Maybe other packages can do this? I assume the words are represented by a vector (300d), but any other options are also Ok. This task can be done in a cycle, but there should be a more effective way for sure. This task fits the TensorFlow, pyTorch, and similar packages, but I'm not familiar with details of these packages.

Solution

The solution was to use something like Spotify Annoy which uses Approximate Nearest Neighbours method. There are some other libraries to do the nearest neighbour search.
