Hi, Hello Robot Team: When i run `RE1_migrate_params.py`, the error as follows: `Unable to find file: /home/mrips/stretch_user/stretch-re1-2000/stretch_user_params.yaml Please run tool RE1_migrate_params.py or verify if Stretch configuration YAML files are present before continuing.` In my stretch\_user folder, i cannot find stretch-re1-2000 folder, how can i generate the folder and these param yaml files ? ---

Hello @jie0530, the `stretch-yyy-xxxx` folder contains robot calibration data unique to your Stretch robot. It is not generated by the migration tool. You can log in to the default account on your Stretch and find your robot’s calibration directory in the “~/stretch\_user” folder. More details [available here](https://github.com/hello-robot/stretch_install/blob/master/docs/robot_install.md#back-up-robot-configuration-data). ---
