target library 対象となるライブラリ(コード)

Describe the bug バグの説明
X.shape=(2500, 900)程度のサイズのデータXに対して学習ができない。メモリの占有容量が大きく、スワップ領域を利用するため学習が非常に遅くなる。

原因として考えられるのは以下。これだと一度(2500,2500,9)を確保する必要があり、double型と考えると45GB程度必要になる。

To Reproduce 再現手順
Steps to reproduce the behavior 挙動を再現するための手順:

  1. X.shape=(2500, 900)程度のサイズのデータXを用意
  2. fitさせる

Expected behavior 期待される振る舞い
計算時間はしょうがないとして、とりあえず回って欲しい。
