Hello,
doing Model({y: 0.}) or CallableModel({y: 0.}) (whatever the constant value in the expression) returns:
AttributeError: 'float' object has no attribute 'free_symbols'
That is a problem when, for instance, we want to create a model after n-derivations and variables are no longer present in the expression.
Could please fix that or tell me if a work around exists.
Thanks,
Patrick
