Error during Model Conversion Process - Impact Inquiry

[liuweixue001]

Hello,

I hope this message finds you well. I followed the tutorial to successfully convert the model; however, an error occurred during the model conversion process. I am seeking clarification on the potential impact of this error.

The specific error message I encountered is as follows:

[08/23/2023-10:06:30] [V] [TRT] Engine Layer Information:

I would appreciate it if you could kindly provide information about the potential consequences of this error. Does it affect the converted model's functionality or performance?

Thank you very much for your assistance.

I encountered the same problem, but the code ran successfully. However, the inference time of the DLA model is much longer than the 4ms in the tutorial, and the actual inference time is about 30ms：

**
././build/cudla_yolov5_app --engine ./data/loadable/yolov5.int8.int8hwc4in.fp16chw16out.standalone.bin --image ./data/images/image.jpg --backend cudla_int8

DLA CTX INIT !!!
ALL MEMORY REGISTERED SUCCESSFULLY
Run Yolov5 DLA pipeline for ./data/images/image.jpg
SUBMIT CUDLA TASK

Output Tensor Num: 3
SUBMIT IS DONE !!!

I get same error on Jetson Orin AGX, I think maybe the trt version need 8.6.0 but for jetpack, trt only is 8.5.3, so when trtexec deal with the onnx , DLAalone feature is not support.
Maybe need repo docker images?

Which DOS/Jetpack you are using? You need DOS 6080+ or JP 6.0+ to get the perf in our readme.

Thanks for reply,
My JetPack version is 5.1.2, and it's the latest version I can get in all jetpack archives: (https://developer.nvidia.com/embedded/jetpack-archive)
how can I get JetPack 6.0+? or is there a docker image to verify the performance?

Unfortunately no, You have to wait for its release :-(

I don't think Jetpack 6.0+ is workful, I have tried jetpack 6.0, it had some other issue in running bash loadle.sh

result.jpg has no result boxes!
