@giovanni94s I was able to find the cached model located at:
~/.cache/torch/sentence_transformers.
I then copied the model directory to ./models and used:
model = SentenceTransformer('./models/sentence-transformers_multi-qa-MiniLM-L6-cos-v1') to load it from the local path. I believe it should be possible to download the model if it isn’t available in the cache directory.
