 **Update 21/12/2020:** I created an image of my SD card [here](https://drive.google.com/file/d/1jg68ySnTt4Zm_hb4JVZKKWXRWkDucqUu/view?usp=sharing). You can flash and run this image on Jetson Nano.
 
-**For TensorRT 7 support:** Currently, only TensorRT 5 and TensorRT 6 are supported. TensorRT 7 has a lot of deprecated APIs and I think there is no way to run this project directly with that version. I don't have time to continue with this project soon, so I really need your contributions to extend this project further.
