I am trying to work with the graph composer on the new DS 6.3. When I startup the composer, I receive the following errors:

2023-08-21 01:25:27  [Error] [omni.exp.graph.composer.registry_window] Failed to get repo list: <AioRpcError of RPC that terminated with:

How to solve this problem?

I am experiencing the same problem. It effects both local install as well as docker image.

Solution can be found at the link below. TLDR, first run “gxf_server” in a terminal then start up composer and you will be able to use the program.

Please follow the instruction Application Workflow — DeepStream 6.3 Release documentation

I successfully started Graph Composer according to the above document, but encountered another issue. If I close the gxf_server terminal and then open another terminal to start gxf_ server, it will prompt that this service has been started and the Composer cannot run normally.

I found that restarting the computer can solve this problem. Is there a more convenient way?
