• K-means clustering is used for training. If the training dataset is small, the query precision may be affected.
• The value of n must be the same as that of nlist, which generally cannot exceed 1e9.
• The x must be a non-null pointer with a length of dim x n. Otherwise, an out-of-bounds read/write error may occur, causing program breakdown.
