问题描述
使用 matplotlib 绘制多幅图出现如下问题 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). fig, ax = plt.subplots(figsize=(10, 10))。
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`).
fig, ax = plt.subplots(figsize=(10, 10))
原因分析：
出现这种问题就是你同时绘制了多幅子图会占用大量内存，提醒你不需要时将其关闭文章来源：https://www.toymoban.com/news/detail-640410.html
解决方案：
在循环内，每次使用 plt.plot() 绘制结果后，使用代码将其关闭，再重新绘制新的子图文章来源地址https://www.toymoban.com/news/detail-640410.html
plt.close()
