Row in matrix python
Webin python. A magic square is an n x n matrix in which each of the integers 1, 2, 3...n2 appears exactly once and all column sums, row sums, and diagonal sums are equal. For example, the attached table shows the values for a 5 x 5 magic square in which all the rows, columns, and diagonals add up to 65. Web似乎這不應該占用太多內存，將 1-row-CSR 與 20mil-row-CSR 進行比較應該輸出 1x20mil ndarray。 Justy FYI：X 是內存中約 12 GB 的 CSR 矩陣（我的計算機只有 16 個）。 我試過研究 gensim 來代替它，但我找不到一個很好的例子。 對我缺少的東西有什么想法嗎？
