$Use DLA on Jetson NX

Accelerated Computing Intelligent Video Analytics DeepStream SDK

Hi,
I am using DS 5.0 on Jetson NX.
I want to use DLA engines while running YOLO classifier.
In documentation, it says that enable-dla only supported for Jetson AGX.
I tried to add enable-dla=1 and use-dla-core=0 in my config file, but it fails.
Is it possible to use DLA on NX?

Hi,

We can reproduce this issue in our internal environment.
Will let you know once we got any update.

Thanks.

Hi,

Thanks for your patience.
We found this issue is caused by the non-supported network mode.
Please noticed that DLA only support fp16 and int8 mode but our default setting in YOLO sample is fp32.

So please also update the network mode into fp16 when using DLA.
config_infer_primary_yoloV3_tiny.txt

[property]
gpu-id=0
enable-dla=1
use-dla-core=0
...
## 0=FP32, 1=INT8, 2=FP16 mode
network-mode=2
...

Thanks.
