Dear Flatland Team:

I have faced a weird error during local evaluation which I don’t know to fix. Could you please help? The issue was also mentioned here but didn’t get any response: https://gitlab.aicrowd.com/flatland/flatland/issues/322

Listening at :  flatland-rl::FLATLAND_RL_SERVICE_ID::commands
Error :  env_client.step called before env_client.env_create() call
Traceback (most recent call last):
  File "/home/[user]/miniconda3/envs/flatland-rl/lib/python3.6/site-packages/flatland/evaluators/service.py", line 873, in run
    self.handle_env_step(command)
  File "/home/[user]/miniconda3/envs/flatland-rl/lib/python3.6/site-packages/flatland/evaluators/service.py", line 588, in handle_env_step
    "env_client.step called before env_client.env_create() call")

Many thanks!

Best,
Beibei
