13.2 Run a local submission on the Duckiebot crash

[plafer]

I ran dts duckiebot evaluate --duckiebot_name DUCKIEBOT_NAME (with bot udem05) and got the following error. I used challenge-prediction/predictor_last as the working directory. I can confirm that I successfully connected to the bot (could ping it and ssh in), etc.

Potentially related, the previous step dts start_gui_tools DUCKIEBOT_NAME just hanged at

INFO:dts:Running interactive_gui_tools_udem05 on localhost with environment vars: {'HOSTNAME': 'udem05', 'ROS_MASTER': 'udem05', 'DUCKIEBOT_NAME': 'udem05', 'ROS_MASTER_URI': 'http://172.19.0.252:11311', 'QT_X11_NO_MITSHM': 1, 'DISPLAY': ':0'}

I don't think these two things are related.

1. The predictor challenge doesn't have an "embodied" version so you can't run it on the document. So maybe try one of the baseline options for the embodied challenges duckiebot evaluate
2. are you sure it hanged or was it just pulling the image onto your laptop? To test do docker pull duckietown/rpi-duckiebot-base:master19 and see the status. (we should output the status of the pull so that it's more clear...)

[plafer]

You're right, it was pulling the image. I updated the documentation to warn against it, but yes we should definitely show some progress (I didn't even know it was pulling some docker image).

As for the duckiebot evaluate, I tried with baseline-duckietown, and eventually hit this error:

Traceback (most recent call last): File "duckiebot_bridge.py", line 49, in main() File "duckiebot_bridge.py", line 46, in main node.run() File "duckiebot_bridge.py", line 37, in run commands = self.ci.write_topic_and_expect(u'get_commands', expect=u'commands') File "/project/src/zuper-nodes-python2/src/zuper_nodes_python2/outside.py", line 78, in write_topic_and_expect ob = self.read_one(expect_topic=expect, timeout=timeout) File "/project/src/zuper-nodes-python2/src/zuper_nodes_python2/outside.py", line 170, in read_one raise TimeoutError(msg) socket.timeout: Timeout detected on /fifos/agent-out after 1 messages. Expected topic "commands".

That one is not reproducible; all the other ones, I got (no clue why it just exits):

As for the RL baseline, my computer is too slow to properly train it (it would take forever), so I'll try that when I get my new one.

can you give us steps to reproduce?
