Hi Abhishek,
As suggested by the error message, you don’t seem to have the python package
for protobuf. Please ensure that is available and it should work just fine.

Subject: Re: [gem5-users] How can I trace data of Cache?
Hello Andreas,
When I get execute decode_packet_trace.py script, I get the following error. I
am setting protoc manually as mentioned in the script and executing it from
gem5 root. I have module protoc installed on my system. Can you please give us
a simple example on how to use the script to decode trace.
Thanks for your help.
Regards,
Abhishek

Hello all,
Thank you Andreas for writing wiki.
I have attached CommMonitor between L2 and membus. After simulation,
CommMonitor is present in config.json and stats.txt. However, I am not able to
read trace_file associated with CommMonitor. It contains garbage data. I tried
using script in util/ as well. Additionally, I get following warning when I
start simulation. I have attached snapshot below.
Can you please take a look into this and let me know what is wrong.
Thanks for your help and support.

Abhishek,
Look at this mail thread

You need to have google-protobuf installed to use CommMonitor.
