找不文件错误

看一看感觉只有configs/pascal_voc/my.py的文件 你的好像不是官方的？ 感觉问题是出在这边

你可以在mean_ap_visualize.py 365行（在 plt.savefig('/mmdetection/PR_Curve_each_class.png')之前一行）加上 plt.show() ，可以将PR曲线图自动展示出来再保存下来。目前，我也只能是这样解决这个问题，希望能对你有所帮助。

同样，在visualize.py中进行同样的操作，就可以画第一个

我把这一行代码里的路径改成绝对路径之后就可以正常保存图片了。

就是路径的问题，没有/mmdetection这个文件夹，可以改为./PR_Curve_each_class.png即可

'/mmdetection/PR_Curve_each_class.png'改成'./mmdetection/PR_Curve_each_class.png',加个点就行了。作者写相对路径的时候漏了个点。另外这些报错可不止路径的问题呀，你大概是用的新版mmdetection，需要重新修改mean_ap文件。
