Error with pygame_client.py

[nina124]

After a long long trouble shooting, finally I could run the step 7 in Installation python3 -m minos.tools.pygame_client. Thanks for the detailed instructions in issues. Still, I met the following error. It seems there is some bug in pygame_client.py

➜ minos git:(master) ✗ python3 -m minos.tools.pygame_client 2018-03-14 10:24:18,758 INFO {'stk_git_hash': '966f84d', 'machine': 'nina-lab', 'sim_git_hash': '966f84d', 'sim_id': 'sim00'} Starting simulator... 2018-03-14 10:24:18,769 INFO sim00:Starting sim server at /home/nina/work/minos/minos/server/server.js with port 42001 2018-03-14 10:24:20,433 INFO sim00:connect observation_space {'measurements': {'direction_to_goal': BoxSpace(range=None, shape=[0, 3]), 'offset_to_goal': BoxSpace(range=None, shape=[0, 3]), 'distance_to_goal': BoxSpace(range=None, shape=[0, 1])}, 'sensors': {'color': BoxSpace(range=[0, 255], shape=[256, 256, 4]), 'force': BoxSpace(range=[None, None], shape=[4, 1])}} Simulator started.

Hi @nina124 , thank you for trying MINOS!

The error is likely due to a failure in loading the scene. Within the working directory from which you start the client, a set of log files will be generated in logs//simserver.log and logs//simulator.log. Can you please inspect both and quote here any errors that you see in these log files (in particular simserver.log)?

@msavva I just find I made a stupid mistake. The $NODE_BASE_URL pointed to the original SUNCG dataset instead of the minos package. Thank you so much for always kindly answering these questions. So helpful for beginners like me.
