TPU Index is a package for fast similarity search over large collections of high dimension vectors on TPUs. This package was built to support our project that we developed for https://tfworld.devpost.com/.

!pip install tpu-index
from tpu_index import TPUIndex
index = TPUIndex(num_tpu_cores=8)
index.create_index(vectors) # vectors = numpy array, shape == [None, None]
...
D, I = index.search(xq, distance_metric='cosine', top_k=5)
- Add more distance metrics
- Optional GPU support
