WARNING : Not enough validators and IndexError: list index out of range

I have two questions:
First, what is nodeID = (self.topo.rank * self.config.maxNodesPerRank) + i in your network.py using for. Because self.topo.rank is always 0

second, when I ran the test.py, it gave me the following result:

Traceback (most recent call last):
File "/Users/nien-ting/Desktop/shardSim-master/test.py", line 23, in

File "/Users/nien-ting/Desktop/shardSim-master/shardSim/node.py", line 130, in validate
self.proposers.append(self.currentCommittee[0])
IndexError: list index out of range

could you tell me if I didn't run it right or something.

Hello, are you running with multiple processes with MPI? Otherwise, you won't see multiple ranks..

Hello,I have two questions:
First, Can this code run under PyCharm?
Second，after nodes are sharded, what is the consensus mechanism within the committee?

Hello，I run this code under PyCharm,the following question arises.
Have you ever had this problem? What's the solution?
please you tell me，thank you so much!

My suspicion is that you are not using MPI and then you do have not enough processes to run the simulation, you should configure your simulation for one single process if you just one to run one single process. However, I want to mention that this simulator was developed 3 years ago and it does not comply with the recent developments on the Eth2 specification.
