Hi @huojinshensss. If the data download is repeatedly failing, I would suggest that you try downloading the images one at a time. There is an example script in another post that demonstrates how to do this: How to have access to the data - #4 by nick.burns
I would also suggest using the Asia server, as that should be a bit faster: s3://drivendata-competition-biomassters-public-as/
Let me know if that helps. Good luck!
