Though there is no error message generated, I am unable to find the hello_world/system.cpu.traceListener.datatrc.helloworld.out file.

Please suggest if I am missing any step here.

I generated traces for the hello-world program, but am unable to decode it.

Did not find proto definition, attempting to generate
TypeError: Descriptors cannot be created directly.
If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:
1. Downgrade the protobuf package to 3.20.x or lower.
2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

upgraded protobuf to 3.20.3.~/temp/gem5$ pip3 list | grep proto

However, the same symptom persists as above.
Tried option 2, and set the environment variable.After this,the following output is seen (in >>> <<<):>>>
