Error: Set affinity failed

Hi,

i’m trying to follow the instructions on the docs to run high_level_mode on the a1. I’ve connected a PC via LAN and can ssh into the rasberry pi. When typing roslaunch mbs_unitree_ros high_level_mode.launch the following error occurs: Error: Set affinity failed.

The full response:

I’m running Ubuntu 18.04 on Hyper-V. Can this be the problem? If yes, what VM service do you recommend?

Thank you for your time,

Felix

Hi Felix,
Are you running your source code on Rasberry Pi or on your VM?
I have never used this with VM.

HI,
I was running it on my remote PC on a VM (Hyper-V). I resolved the issue by running it on WSL. I thought I can only run the High_Level_Mode node on a remote PC. Can I also run it on the Rasberry Pi in the robot?

Hi,
I think running it on a RPI should not be a problem.
