报错的信息提示的是 /tmp/pip-req-build-dbxqlxdj/setup.py 这个文件不存在。

看你的安装命令 /tmp/pip-req-build-dbxqlxdj/ 是从 https://github.com/AIcrowd/coco.git 这个git仓库clone下来的

检查下是否能连接到 https://github.com/AIcrowd/coco.git 这个仓库地址，检查方式：

1.执行  ping github.com，查看是否能正常返回

2.执行 git clone https://github.com/AIcrowd/coco.git 查看能否将项目clone下来
