Usage of bctrainer.py

[AlexWanghaoming]

Hi, Could you please offer an example of bctrainer.py. I input the trajs file collected from web user interface but meet an error:

Traceback (most recent call last):

raise ValueError('The value argument must be within the support')
ValueError: The value argument must be within the support

My torch version is 1.8.1, stable-baselines3 version is 1.2.0a0

Thanks
