Is the FAST sampler not compatible with the parameter type list? #265

Closed TheodorB closed 3 years ago

TheodorB commented 3 years ago

So I get this error when running the FAST algorithm:

raise ValueError("Bounds are not legal") ValueError: Bounds are not legal

and parameters generated are these:

[(nan, 'Ks', 0., 0., 0., 0., False) (nan, 'Alpha', 0., 0., 0., 0., False) (nan, 'n', 0., 0., 0., 0., False) (nan, 'P2H', 0., 0., 0., 0., False) (nan, 'P2L', 0., 0., 0., 0., False) (nan, 'rootDepth', 0., 0., 0., 0., False) (nan, 'C50', 0., 0., 0., 0., False) (nan, 'rain_err', 0., 0., 0., 0., False) (nan, 'thetar', 0., 0., 0., 0., False) (nan, 'thetas', 0., 0., 0., 0., False) (nan, 'thetai', 0., 0., 0., 0., False) (nan, 'etp_err', 0., 0., 0., 0., False)]

Although I definitely passed a list of values.

Is the FAST sampler not compatible with the parameter type list?

Is there a work-around it?

this was discussed via pm. In case one comes accross this: It is not possible to use the fast sampler with a given parameter list. In fact spotpy.parameter.list is designed to work with Monte Carlo sampler only.
