Running sample graph reference app test1 according to Deploy Graph section in the below URL fails on x86_64
https://docs.nvidia.com/metropolis/deepstream/dev-guide/graphtools-docs/docs/text/GraphComposer_app_Workflow.html#deploy-graph
The errors on console in Graph Composer UI:
2022-05-09 00:49:37 [Error] [carb.python] [./registry/backend/model.py:398] Do not have permissions to save the graph /opt/nvidia/deepstream/deepstream-6.0/reference_graphs/deepstream-test1/deepstream-test1.yaml
2022-05-09 00:49:37 [Error] [carb.python] [/tmp/.tmpNvXgRaphComposer/run/composer/omni.exp.graph.composer/omni/exp/graph/composer/run_graph_window.py:252] Saving Graph /opt/nvidia/deepstream/deepstream-6.0/reference_graphs/deepstream-test1/deepstream-test1.yaml failed!

However, when I follow the Execute Graph using command-line (execute_graph.sh script), it works on x86_64 with the command:
/opt/nvidia/graph-composer/execute_graph.sh deepstream-test1.yaml parameters.yaml -d …/common/target_x86_64.yaml

How can I work the reference app on the Graph Composer UI?

thanks

I can not reproduce the error. Can you provide more details?

#4

This issue happens when I follow the step 4 and 5 in Load Graph at the below:
https://docs.nvidia.com/metropolis/deepstream/dev-guide/graphtools-docs/docs/text/GraphComposer_app_Workflow.html#load-graph
I just selected the parameters.yaml file with deepstream-test1.yaml file.
If I choose only deepstream-test1.yaml file without the parameters.yaml one, the problem does not appear.
parameters.yaml (912 Bytes)

What do you mean by “I just selected the parameters.yaml file with deepstream-test1.yaml file”? We have tested this case, it works.

#6

Can you try to run the composer UI under “root”

To Fiona,
Thank you for the information. it works after applying your advice and also when I tried the situation I did not do well, it works now.
Could you please tell me the reason that the issue happens?
thanks

The reason is just the folder is root R/W only.
