Also, this is a duplicate of [How can I train multiple 'trainer' in same environment?(or embed trained trainer in environment?) - #3 by coco](https://discuss.ray.io/t/how-can-i-train-multiple-trainer-in-same-environment-or-embed-trained-trainer-in-environment/8700/3) to which you still have to answer.  
Please don’t open a new thread if you have opened another one for the same problem. 🙂
