Script python -m lerobot.calibrate --teleop.type=so101_leader --teleop.port=/dev/ttyACM1 --teleop.id=the_leader does not create calibration file

System Info

Hi

If someone can tell me how to retrieve the lerobot version I will be nice

I noticed that when I tried to calibrate the leader, the script does not create a calibration json file 

Only the calibration of the follower successfully created the file the json file.

I will have a look to check where it happens - or what is the equation to update the json file knowing the table created by the calibration process?

Information

• One of the scripts in the examples/ folder of LeRobot
• My own task or dataset (give details below)

Reproduction

enter:
python -m lerobot.calibrate --teleop.type=so101_leader --teleop.port=/dev/ttyACM1 --teleop.id=the_leader
the table is properly updated:

NAME | MIN | POS | MAX
shoulder_pan | 903 | 2026 | 3346
shoulder_lift | 838 | 847 | 3175
elbow_flex | 928 | 3134 | 3140
wrist_flex | 921 | 2552 | 3115
wrist_roll | 119 | 1977 | 3925
gripper | 2046 | 2050 | 3246
and when I press 'enter' - there is .json file created

Expected behavior

The following message for the leader
Calibration saved to /home/fabrice/.cache/huggingface/lerobot/calibration/robots/so101_follower/follower.json

So you don't get any Calibration saved to... for the leader?

Hi, yes this is the case. I have to take a look at the code to find out why. From the table generated by the calibration I can also build the json but need to know how to compute the "homing offset"
