[TRT] attempting to open engine cache file .2.1.GPU.FP16.engine

Autonomous Machines Jetson & Embedded Systems Jetson TX2

I’ve recently re-installed all NVCaffe, DIGITS, Jetson-inference and the environment seems to have changed slightly such that I can no longer run the following without errors:

$ cd jetson-inference/build/aarch64/bin
$ NET=DetectNet-COCO-Dog
$ ./detectnet-camera \
--prototxt=$NET/deploy.prototxt \
--model=$NET/snapshot_iter_38600.caffemodel \

It seems that, although I specify: NET=DetectNet-COCO-Dog, there’s no search for a cache file at this location.

Detectnet-camera works fine with the following, which should have produced a cache somewhere?

$ cd jetson-inference/build/aarch64/bin 
$ ./detectnet-camera coco-dog

Here’s the full error … Please advise!

Hi,

The log indicates that the application cannot find the model path correctly.
As you already found, you can solve this issue by setting the $NET parameter:

Thanks.

Hello I am trying to implement jetson-inference tutorial but I after I got to the building your rpo from source i got this error

[TRT]  TensorRT version 3.0

can you help me

Hi,

Please follow this page to build jetson_inference from source:
[url]https://github.com/dusty-nv/jetson-inference/blob/master/docs/building-repo.md#building-the-repo-from-source[/url]

Based on your log, the model is not well-downloaded in your environment.
Have you executed the cmake command successfully?

Thanks.

Hi, AastaLLL

thanks for replying.

yes, I have redownloaded and reinstall the environment but it didn’t work. and the cmake error didn’t show any error.

but when I tried with my own datasets both the image classification and object detection model worked. but it didn’t work with the model that used in the tutorial.

thanks.

Hi aosanshugaa, what command are you running to launch the program from terminal?

8

hi dusty_nv
when i try the example from the tutorial it doesn’t work

./imagenet-camera googlenet

or

./detectnet-camera  \
--prototxt=$NET/deploy.prototxt \
--model=$NET/snapshot_iter_13110.caffemodel \
--labels=$NET/labels.txt \
--input_blob=data \
--output_blob=softmax

it shows this error

Hi,
I have exactly the same problem with segnet-console using Pascal-VOC dataset.
I run :

./segnet-console test.jpg output_0428.png \
--prototxt=$NET/deploy.prototxt \
--model=$NET/snapshot_iter_8790.caffemodel \
--labels=$NET/pascal-voc-classes.txt \
--input_blob=data \ 
--output_blob=score_fr

And I get :

[TRT]  requested fasted precision for device GPU without providing valid calibrator, disabling INT8

I’m also pretty sure to have properly built jetson-inference, Do you have any idea to solve this ?
