Distribution difference between Observations and Predicted Actions

The 'turn_rate_global' feature in the 66-dim observation has max, min, mean approximately 0.05, -0.05, 0.
While I generated some trajectories with PS-GAIL and get the 'mean' action output with statistics max, min, mean as 1.18, -1.36 -0.07.
Why are the two distributions different? Are they with the same units?

Can you share more details about how you are calculating these statistics, how many trajectories you are generating, etc? The units should generally be the same, and I can provide more insight if I have more details about what you are doing.

You were right. The number of my sampled trajs is too small.
Thank you!
