Hi

I understand this issue is not related to Dora, in case someone has met this environment issue and have a workaround?
My PC is Ubuntu18.04 CUDA 11.04 with latest docker and Nvidia docker 2 installed.

when in this step I got error

./scripts/launch.sh

Oh sorry, I think my github notification wasn't linked to this issue page.

There are many downloads during the docker image build, and some downloads can fail. I would recommend trying to build it again.
