BUG“Could not find a BenchBot supervisor” #31

Closed rex131 closed 3 years ago

rex131 commented 3 years ago

I found something wrong when I was trying to run the example of "benchbot_submit --example hello_passive". i have finished the second step and I have gatten the pic1. but when i went to third step, it told me "Could not find a Benchbot supervisor"(pic2). how can i solve this problem? it has confused me for a long time. here are the details:

File ".hello_passive/hello_passive", line 11, in BenchBot(agent=GuidedAgent()).run() File "/home/turtlepc-04/.local/lib/python3.6/site-packages/benchbot_api/benchbot.py", line 84, in init self.start() File "/home/turtlepc-04/.local/lib/python3.6/site-packages/benchbot_api/benchbot.py", line 368, in start "Are you sure it is available?" % self.supervisor_address) requests.exceptions.ConnectionError: Could not find a BenchBot supervisor @ 'http://benchbot_supervisor:10000/'. Are you sure it is available? IMG_20210709_215123 IMG_20210709_215257_edit_138013332824253

Thanks for reporting @rex131 .

I'll need a bit more information to understand what is happening on your system.

Can you post the output of the active benchbot_run command:

benchbot_run --robot carter --env miniroom:1 --task semantic_slam:passive:ground_truth 2&>1 | tee benchbot_run.log

And the output of your benchbot_submit command:

benchbot_submit --example hello_passive 2&>1 | tee benchbot_submit.log

And lastly some local network information (while benchbot_run is running):

ip a
curl benchbot_supervisor:10000

This will help me get an understanding of where the issue could be coming from.

the first one is just a picture(pic1) IMG_20210709_215123

the scond "benchbot_submit" command nothing happened turtlepc-04@TurtlePC-04:~$ benchbot_submit --example hello_passive 2&>1 | tee benchbot_submit.log turtlepc-04@TurtlePC-04:~$

the third " ip a":

the last "curl benchbot_supervisor:10000"

turtlepc-04@TurtlePC-04:~$ curl benchbot_supervisor:10000 curl: (5) Could not resolve proxy: http

btalb commented 3 years ago

Thanks for the information @rex131 .

The last command is telling me that the issues are being caused by the local network configuration on your machine.

Are you running a proxy? If yes, what limitations does it have? It appears to be blocking your local http traffic which will stop BenchBot's process intercommunication.

i have successfully solved this bug by turning off the vpn. thank you for your time
