Unable to build mxnet on Jetson TX2

Hi there,

I’ve followed the guide here:

I was successfully able to build it on the jetson nano, but while trying to build on the TX2, I’m getting an error during the installation and when I try to import the library.

Any advice is much appreciated!

File “resnet18-mxnet-trt.py”, line 1, in
import mxnet as mx
File “/usr/local/lib/python3.5/dist-packages/mxnet/init.py”, line 23, in

Hi,

The error complains about there is no TensorRT-7.1 package in your environment.
Have you installed it?
You will need to use JetPack4.4 to get the TensorRT-7.1 package.

Thanks.

Great! Thank you. I’m using a non-stock carrier board so the flash process is a little involved.
