how to set the distance_threshold

[QAbot-zh]

In the Fetchxxx-Env, the env's distance_threshold is set as 0.05 default to determine whether a task is completed successfully. I try to modify it by using env.distance_threshold = 0.01(or other value) because I think 0.05m is too rough for some tasks. But it doesn't work! (When the success_rate is 1.0, the distance between the achieved_goal and the desired_goal is 0.04x, which is larger than I set.)
How should I do to change the conditions for determining whether a task is complete?

You can change it directly into the library of gym.
Go to /path/to/lib/python3.9/site-packages/gym/envs/robotics/fetch/reach.py. There you can modify the distance_threshold, object_range and target_range. Also the position of the robot in the robot0:slide0,1,2 variable about x,y,z respectively.
I don't know how to set the variable directly in env but hope this ca help 👍
