日記,そして備忘録

Python の matplotlib.pyplot でグラフをたくさん作るとき

自分用のメモ.

RuntimeWarning: More than 20 figures have been opened. Figures created through the pyplot interface (matplotlib.pyplot.figure) are retained until explicitly closed and may consume too much memory. (To control this warning, see the rcParam figure.max_open_warning).

を回避するためにグラフ作ったときの最後に

plt.close()

を書けば良いはず.
