解决pycococreatortools安装问题

我的环境：

python:3.8.18

numpy:1.24.4

问题一：

用git文档的方法下载失败：

pip install git+git://github.com/waspinator/[email protected]

 解决：

用这行 pip install git+https://github.com/waspinator/pycococreator.git

问题二：使用pycococreatortools.binary_mask_to_polygon的时候报错

ValueError: setting an array element with a sequence. The requested array has an inhomogeneous shape after 1 dimensions. The detected shape was (2,) + inhomogeneous part.

解决：

在这个函数定义内加上一行 contours=sorted(contours,key=lambda x: len(x),reverse=True)[0:1]

所有这些问题都在git的issue里有
