Hi all ,  
I am planning to use rllib to train a custom external enviroment. Firstly i run the example Cartpole\_server.py script in colab, and the Cartpole\_client.py script in my local laptop. Then i connect to the colab public ip via ssh and remap the localhost port to my local laptop. But the client could not recive the correct data but raise an error.  
I am so grateful if any friends could have some advice about how to depoly a external envs and train it in the cloud, thank you so much!!  
(1)the output in colab of the server script:  
(pid=1252) 2021-11-15 07:24:08,211  
INFO policy\_server\_input.py:190 – Sending worker creation args to client.  
(pid=1252) 127.0.0.1 - - [15/Nov/2021 07:24:08] “POST / HTTP/1.1” 200 -  
(2)error occoured in the client script in local laptop.

Hi @Slientes ,

in my opinion using Google Colab is more a hassle than making things easier for you. I run my experiments in the Google Cloud by using a ray cluster on some servers from Compute Engine.

See this [topic](https://discuss.ray.io/t/running-rllib-with-ray-tune-on-gcp/3790) for more infos on how to do it.

Hope this helps
