I have been updating my stretch RE1 to Ubuntu20 and following [this guide](https://docs.hello-robot.com/0.2/stretch-install/docs/robot_install/). I am getting an error in the post install steps while trying to run the RE1\_migrate\_params.py. I have attached a screenshot of the error. Any help with this would be greatly appreciated!

Hi @Edelio_Taboada, would you run `pip3 list | grep stretch` in a terminal and post the output here?

Not sure what tool you are running but I got the same error because it was trying to find the dex wrist when I had a gripper installed. This can be changed within the param yaml files

Thank you, that fixed worked. I went into the param yaml files and just removed the part that said params:  
stretch\_tool\_share.stretch\_dex\_wrist
