where can I get the right cudnn7 packages for tx1/tx2

I have update my Jetson tx1 board to Jetpack3.1,and installed TensorRt3.0 completely,but when excute sample, it notice me that
./sample_mnist: error while loading shared libraries: libcudnn.so.7: cannot open shared object file: No such file or directory
.I try to download cudnn from https://developer.nvidia.com/cudnn,but only found the packages for x86/x64,where I can get the right cudnn7 packages for tx1/tx2.


Please install TensorRT with .deb package.
All the required package are included in the .deb package.


Thank you for your hints,I reinstalled the TensorRT with .deb package,and the problem is solved.
