(name, param_type, value)
return param_type(value)
Cast hparam to the provided type, if compatible.

  Args:
    name: Name of the hparam to be cast.
    param_type: The type of the hparam.
    value: The value to be cast, if compatible.

  Returns:
    The result of casting `value` to `param_type`.

  Raises:
    ValueError: If the type of `value` is not compatible with param_type.
      * If `param_type` is a string type, but `value` is not.
      * If `param_type` is a boolean, but `value` is not, or vice versa.
      * If `param_type` is an integer type, but `value` is not.
      * If `param_type` is a float type, but `value` is not a numeric type.
Cast hparam to the provided type, if compatible.
Cast hparam to the provided type if compatible .
