How to use faiss's c_api for sift1b dataset? I have setup the env successfully. I read the source code of indexpq.h and found that the function "index" only supports float type data, while the data type of the sift1b dataset is uint8. Do I need to convert each data type to float one by one? Or does faiss support uint8 type data?
Here is the related src code in indepq.h: void train(idx_t n, const float* x) override; void search( idx_t n, const float* x, idx_t k, float* distances, idx_t* labels, const SearchParameters* params = nullptr) const override;
