这个问题实际是由于初始化需要的数据是用github下载的，而在中国大陆访问有限制导致下载失败，如果你对python比较熟悉的话，不难调查出此问题。 解决办法就是是墙外从github下载样例数据，将数据在本地启动一个http文件服务，修改BASE_URL为本地地址即可，启动方式可以了解下python的内置库http.server，或者其他工具也可以

1. start a vpn server at localhost with http proxy
2. set docker network= host add HTTPS_PROXY env to run superset container

example

sudo docker run -d --network host -p 8080:8080 --env HTTP_PROXY="http://127.0.0.1:7890" --env HTTPS_PROXY="http://127.0.0.1:7890" --name superset apache/superset
