It is also important to note that the CAGRA 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: a. kDLDataType.code == kDLFloat and kDLDataType.bits = 32 b. kDLDataType.code == kDLFloat and kDLDataType.bits = 16 c. kDLDataType.code == kDLInt and kDLDataType.bits = 8 d. kDLDataType.code == kDLUInt and kDLDataType.bits = 8 2. neighbors: kDLDataType.code == kDLUInt and kDLDataType.bits = 32 or kDLDataType.code == kDLInt and kDLDataType.bits = 64 3. distances: kDLDataType.code == kDLFloat and kDLDataType.bits = 32
