根因分析

保存图形时 figsize*dpi 在任一维度超过 65535 像素，超出后端对 PNG/JPEG 的限制。

English

Saving a figure with figsize*dpi exceeding 65535 pixels in either dimension, which exceeds the PNG/JPEG limits enforced by the backend.

解决方案

  1. 95% 成功率 
    fig.set_size_inches(20, 16)
fig.savefig('out.png', dpi=150)  # 3000x2400 px
  2. 92% 成功率 
    fig.savefig('out.pdf')  # no pixel limit for vector backends

无效尝试

常见但无效的做法:

  1. 92% 失败

    Higher dpi worsens the pixel count and triggers the same limit.

  2. 85% 失败

    'raw' is not a valid format for savefig; the size limit still applies to raster backends.
