根据论文源码https://github.com/facebookresearch/detr首先克隆存储库

git clone https://github.com/facebookresearch/detr.git

报错：-bash: git: command not found
解决办法：

sudo apt-get update
sudo apt-get install git-core
git --version

再执行git clone又报了下面的错误

fatal: unable to access 'https://github.com/facebookresearch/detr.git/': gnutls_handshake() failed: The TLS connection was non-properly terminated.

查资料说是https代理的问题，执行下面两条命令再git clone即可

# 取消http代理
git config --global --unset http.proxy
# 取消https代理 
git config --global --unset https.proxy

安装pytorch

pip install torch===1.5.0 torchvision===0.6.0 -f https://download.pytorch.org/whl/torch_stable.html

服务器一直有人在用，等卡空了再去调，待更新
