What OS and version of that OS are you using?

How did you install the P4 development tools?

Have you tried rebooting the system and then running the same command again, in case some state is left over from a previous run that was not fully cleaned up? I am not certain, but perhaps that error message can occur if there is an old simple_switch_grpc process still running from an earlier make run command in the tutorials repository, assuming that the output you show above is from that.

I have resolved this issue now, but I encountered an error while running the packetinout file in ptf tests in p4 gudie. The error is as follows, and I don't know how to solve it. Started simple switch grpc.   Waiting 2 seconds before starting PTF test ...

Before any of the PTF tests in the p4-guide repository can be successfully run, you must create many veth interfaces for them to use in sending and receiving packets. Run the script bin/veth_setup.sh as user root, e.g. sudo path/to/bin/veth_setup.sh.
