GXE run parameters for entities with spaces in their names

[gabriele.proiettimattia]

When running a graph with GXE I’m wondering how I can pass parameters in entities that have spaces in their names (-- which is the default behavior of Composer to put spaces in entities names).

I’m reading the guide at this address Graph Execution Engine — DeepStream documentation but the names never have spaces. Suppose, instead, this example:

application:
  name: myapp1

dependencies:
  - extension: NvDsSourceExt
    uuid: a632d022-3425-4848-9074-e6483ef74366

      video-%u-out: Multiple Data Output1

ui_property:
  position:

    y: 230.0
---
[...]

How would you pass, for example, the parameter uri-list? What I tried is

/usr/bin/gxe -app myapp1.yaml [...] -severity 5 --param="Multi Source Input0/nvidia::deepstream::NvDsMultiSrcInput/uri-list=rtsp://localhost:8554" --param="Multi Source Input0/nvidia::deepstream::NvDsMultiSrcInput/source-id-list=0"

But i get this error in red

2025-02-20 08:49:13.646 ERROR gxf/std/yaml_file_loader.cpp@117: Override parameter string is incorrect:"Multi

I’m using GXE runtime 4.1.0.

Thanks for all your help

We have provided the /opt/nvidia/graph-composer/execute_graph.sh tool to run the DeepStream graph with parameters. Reference graphs — DeepStream documentation

If you have the composer installed, you can modify the parameter directly with composer.
Or you need to save the changed parameters you want to change as a separated parameter YAML file. Then you can use /opt/nvidia/graph-composer/execute_graph.sh to run graph with parameters.

Thanks @Fiona.Chen for your answer I was trying to use the script that you suggest but I get two different errors on x86 and on aarch64. I created a simple graph from the sample deepstream-test1 and removed the real-time rendering for running only the inference. I am using the Docker image nvcr.io/nvidia/deepstream:7.1-triton-multiarch where I installed the composer runtime and the reference graphs.

I created a repo for this purpose at this address Gabriele Proietti Mattia / deepstream-graph-test · GitLab, you can use the sc_run_* scripts for running the graph.

On x86 the graph runs successfully but on Jetson AGX Orin I get:

2025-03-21 13:48:34.535 ERROR gxf/gxe/gxe.cpp@282: GxfGraphRunAsync Error: GXF_FAILURE

Which step am I missing?

Thanks for your support

EDIT:

I also get this warning in Jetson AGX Orin

ERROR: This container was built for NVIDIA Driver Release 560.28 or later, but
       version 540.4.0 was detected and compatibility mode is UNAVAILABLE.

And this is the jetpack version

jetson@agxorin-2 ~/testing [SIGINT]> cat /etc/nv_tegra_release

TARGET_USERSPACE_LIB_DIR=nvidia
TARGET_USERSPACE_LIB_DIR_PATH=usr/lib/aarch64-linux-gnu/nvidia

but from here Installation — DeepStream documentation it should be compatible with DS7.1

EDIT2:

The error on the graph was solved by installing jetpack with

sudo apt install nvidia-jetpack -y

Since the docker image already contains jetpack it is not automatic that jetpack must be completely installed in the host.

Have you run the original deepstream-test1 graph successfully in your environment before you modified anything?
This log shows that DeepStream SDk does not work in your environment.

You can refer to Installation — DeepStream documentation for how to install DeepStream SDK in Jetson.

There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one. Thanks
