Versioning issue for gencode and protobuf

[aitianshi]

I followed the steps of the Micro2024 tutorial (https://astra-sim.github.io/assets/tutorials/micro-2024/7_demo.pdf) but when running commands of slide n.10

python3 generate_all_reduce.py

I got the following error

Traceback (most recent call last):

I saw that protobuf version is required to be 5.*. How can I downgrade gencode to get the same major version ?
