run rl-tcp test_tcp.py stuck at env = ns3env.Ns3Env

[LiYufengzz]

run test_tcp.py which in rl-tcp,some problems occurred.
the code will stuck at this line:
env = ns3env.Ns3Env(port=port, stepTime=stepTime, startSim=startSim, simSeed=seed, simArgs=simArgs, debug=debug)
i use keyboard to interrput:
file "/Users/lyf2481/workspace/ns-allinone-3.33/ns-3.33/contrib/opengym/ns3-gym-master/scratch/rl-tcp/test_tcp.py", line 37, in
env = ns3env.Ns3Env()
File "/usr/local/lib/python3.9/site-packages/ns3gym/ns3env.py", line 381, in init
self.ns3ZmqBridge.initialize_env(self.stepTime)
File "/usr/local/lib/python3.9/site-packages/ns3gym/ns3env.py", line 151, in initialize_env
request = self.socket.recv()
File "zmq/backend/cython/socket.pyx", line 781, in zmq.backend.cython.socket.Socket.recv

File "zmq/backend/cython/socket.pyx", line 186, in zmq.backend.cython.socket._recv_copy

And i want to ask how to solve this problem,thanks a lot

Hey, here in the rl-tcp example..could you identify what all are the state variables they are using?

Hi, I also met this problem and I ran with command: python3 test_tcp.py. All other params are set to default. I found in other issues that reduce steptime may make the execution faster, however, in the env initailization self.ns3ZmqBridge.initialize_env(self.stepTime). The steptime hasn't been used in fact.

I'd appreciate it if someone can help me with this problem, thanks.

I have recently installed ns3-gym.
I also could run the command
cd ./scratch/rl-tcp
./test_tcp.py
which in turn executed and
Got new port for ns3gm interface: 7147
Now how to proceed?
Can i get help on step by step working of "Rl-TCP"
