I am unable to multiply numpy.float64 * SimpleVar, but I am able to multiply SimpleVar * numpy.float64. The error is as follows:

KeyError: "Cannot treat the scalar component 'x'as an indexed component"

where 'x' is of type pyomo.core.base.var.SimpleVar.

I am using Pyomo 5.5.1. Do we have support for numpy parameters in the models?
