Get error when run bash run_modelfree_rl.sh DQN/PPO/DDPG/PG/PG_conti about rl4rs HOT 5 OPEN

We can troubleshoot step by step. After you start the gymHttpServer using "nohup python -u rl4rs/server/gymHttpServer.py &", you can check if the gymHttpServer is working correctly by running "cd rl4rs/server & python gymHttpCilent.py" in another terminal.
Thank you!

Many thanks for your support!
I check the error. The reason may be the rl4rs file's path causing the trouble.

I started the server, but it stopped at this point from nohup.out:
Server starting at: http://0.0.0.0:5000

  OSError: [Errno 98] Address already in use

And then it can not move

from rl4rs.

The error "Address already in use" typically occurs when a port is already in use by another process. You should:
lsof -t -i:5000 | xargs -I {} kill -9 {}

I found the main reason caused by python gymHttpClient.py, I can not run this file, always shows this error:
requests.exceptions.ConnectionError: HTTPConnectionPool(host='127.0.0.1', port=5000): Max retries exceeded with url: /v1/envs/ (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7efe9d2c9828>: Failed to establish a new connection: [Errno 111] Connection refused',))

from rl4rs.

Typically, the error ConnectionError: HTTPConnectionPool(host='127.0.0.1', port=5000): Max retries exceeded indicates that the gymHttpServer.py program is not running with the specified host and port. Ensure that the intended service is running and listening on the specified port. Additionally, I'd recommend reaching out to someone with experience in web development (or GPT-4) for further assistance.
