Training Object Detection from Simulation in Docker on Ubuntu 20.04

Hi, I got my solutions on Ubuntu 18.

Modify the start.sh like this

#if [[ $IS_19 == 1 ]]; then
NV_FLAG="--gpus=all"
#else
#    NV_FLAG="--runtime=nvidia -e CUDA_VISIBLE_DEVICES=all"
#fi

Because I found my docker’s version is 20.
It will use NV_FLAG="--runtime=nvidia -e CUDA_VISIBLE_DEVICES=all", but this will cause the problem.
So I change to NV_FLAG="--gpus=all"
