Hi, recently I had the same errors when I try to install the coach, whether I used the pip3 install -e . or pip3 install rl_coach , these command outputs same error information:

Hi, there's seems to be something messy with your environment. Have you tried installing in a clean virtual_env?

Hi, thanks @galleibo-intel , I tried to install coach in a clean virtual_env and it works. However, when I want to run the preset of CARLA_DDPG, it always crashes when it comes to "Starting to improve simple_rl_graph task index 0": ` coach -r -p CARLA_DDPG Please enter an experiment name: CARLA_DDPG

Creating graph - name: BasicRLGraphManager Creating agent - name: agent simple_rl_graph: Starting heatup Heatup - Name: main_level/agent Worker: 0 Episode: 1 Total reward: -5929.35 Steps: 999 Training iteration: 0 Heatup - Name: main_level/agent Worker: 0 Episode: 2 Total reward: -607.95 Steps: 1097 Training iteration: 0 Starting to improve simple_rl_graph task index 0 Segment fault.... ` I have seen the worker_0.simple_rl_graph_0.json , is it possible caused by the memory size of replay buffer? The original size is 1M, while I only have 8G memory on my computer.

Generally, it might pose a problem, but not so early in the process, as the replay buffer is not filled yet. Closing this issue, as the issue was resolved.
