Are you running the python script? If your ns3 scratch is crash or has compile error, the python script would stuck to wait for the ns3 response. You can run ./waf --run "rl-tcp" first to check if the ns3 script run successfully, you can also modify the ns3-gym/src/opengym/model/ns3gym/ns3gym/start_sim.py start_sim_script function to output the stderr to file to debug
