I tried jetson-reinforcement on my new jetson tx2. It has Tegra R28.1.I have not installed a new jetpack version or the new software yet.

However i received some errors. what is the errors

Can I use jetson-reinforcement together with Tegra R28.1

thanks

Hi, I'm just going through this exercise myself on the TX2. I have Jetpack 3.1 L4T r28.1 installed. Yes I was able to successfully do the build for jetson-reinforcement. Did you try a fresh install of Jetpack 3.1? Seems to be complaining about CUDA. Maybe the symbolic link got deleted. Try this command: sudo ln -s /usr/local/cuda-8.0 /usr/local/cuda. I have CUDA 8.0 installed.

Unfortunately I think that I need to a fresh install of Jetpack 3.1. sudo ln -s /usr/local/cuda-8.0 /usr/local/cuda does not work. thanks
