Datasets Prinz energy get nan

[zhanghaomiao]

When I use the code

from pyemma.datasets import get_quadwell_data
data = get_quadwell_data()

The data get an nan.
when I read the source code, It seems that you don't give the PrinzModel a boundary, such as (-1,1), so it goes into infinty.

Thanks for your report @travelalone!
@Obudo, @amardt which boundaries do you typically use?

[pasqualil]

We don't use boundaries, but this is an issue that arises from the generator's parameters, specifically dt and kt.
We usually set dt=0.001 and kt=1.0, try with those

[marscher]

Thanks! It works with kt=1 and dt=0.01. But shouldn't it also work for higher temperatures?
