“ndarray is not contiguous”错误的含义 “ndarray is not contiguous”错误意味着你尝试对一个非连续(non-contiguous)的NumPy数组执行了某些需要连续内存访问的操作。在NumPy中,数组的连续性(contiguity)是指数组在内存中的布局方式。C-contiguous(C连续)数组是指数组在内存中是连续存储的,且按照行优先(row-major)...

I first tried to solve this with np.ascontiguousarray as suggested here: facebookresearch/faiss#459. That didn't work so I printed X and realized that the one-hot encoder was outputting a sparse matrix of type csr_matrix rather than a ndarray. After setting OneHotEncoder(sparse=False), ...
