@BIGWangYuDong Up unitl now I have tried the following steps :

Step 1: Installed nvidia precompiled wheel as pytorch downloaded from the official site fails to utilize to recognize the GPU in Jetson Nano. For this I have used the following link : PyTorch for Jetson

Step 2 : Tried to follow the normal mmdetection installation from scratch using the following links : https://mmdetection.readthedocs.io/en/v2.2.0/install.html#a-from-scratch-setup-script

Step 2.1 : During compiling mmcv -full from source , the jetson nano simply hangs. MMCV lite installation goes through but if on running the following verification statement from mmdet.apis import init_detector, inference_detector I am thrown with the following error : Error : No module named 'mmcv._ext'. On refering the following issue : #3271, the suggestion is to install the mmcv -full.

My Jetson Nano has been flashed and has nothing else installed in it. It has a 64GB SD card in it.
I am unable to proceed hereone.

Yes, seems that you need to install mmcv-full to avoid the error, using MMCV_WITH_OPS=1 pip install -e . to install mmcv-full from the source code. it will take a while to install the mmcv-full.
I haven't used Jetson Nano before. Issue 1 and issue 2 in MMCV may help you.

@BIGWangYuDong Thank you ! With the initial steps that I mentioned and the link provided under Issue 1 , I was able to setup mmdetection on jetson nano.

I'm trying to install mmcv with this command pip install mmcv-full -f https://download.openmmlab.com/mmcv/dist/cu101/torch1.6.0/index.html it got stuck? will this command work on jetson nano?
