Problem with the example

Hello! I have a problem with starting the example.

I cannot reproduce this. The issue is the panic in the Golang CPU module due to a mismatch in ZMQ versions. There shouldn't be a mismatch if the modules are built with the Dockerfile, so I'm not sure what's going on here.

Can you elaborate on how you built the Docker image you're using to run the example? The Docker image available from this GitHub repo is missing some of the things necessary to run the example, so the Docker image must be built manually using the test target (which is the default target).
