根因分析

尝试将图形保存到不存在的目录。

English

Attempting to save a figure to a directory that does not exist.

generic

解决方案

  1. 95% 成功率 Create the directory before saving 
    import os; os.makedirs('/nonexistent/path', exist_ok=True); plt.savefig('/nonexistent/path/figure.png')
  2. 90% 成功率 Use a valid existing directory 
    plt.savefig('./figure.png')

无效尝试

常见但无效的做法:

  1. Using a relative path without checking current working directory 70% 失败

    If the relative path points to a non-existent directory, the error persists.

  2. Creating the file manually before saving 90% 失败

    The directory must exist; creating the file alone does not create parent directories.
