It is also important to note that the IVF-Flat Index must have been built with the same type of queries, such that index.dtype.code == queries.dl_tensor.dtype.code Types for input are: 1. queries: kDLDataType.code == kDLFloat and kDLDataType.bits = 32 2. neighbors: kDLDataType.code == kDLUInt and kDLDataType.bits = 32 3. distances: kDLDataType.code == kDLFloat and kDLDataType.bits = 32
