code: def convert_variables_to_tensors(obj):
      """Recursively converts Variables in the AutoCompositeTensor to Tensors.
  
      This method flattens `obj` into a nested structure of `Tensor`s or
      `CompositeTensor`s, converts any `ResourceVariable`s (which are
      `CompositeTensor`s) to `Tensor`s, and rebuilds `obj` with `Tensor`s in place
      of `ResourceVariable`s.
  
      The usage of `obj._type_spec._from_components` violates the contract of
      `CompositeTensor`, since it is called on a different nested structure
      (one containing only `Tensor`s) than `obj.type_spec` specifies (one that may
      contain `ResourceVariable`s). Since `AutoCompositeTensor`'s
      `_from_components` method passes the contents of the nested structure to
      `__init__` to rebuild the TFP object, and any TFP object that may be
      instantiated with `ResourceVariables` may also be instantiated with
      `Tensor`s, this usage is valid.
  
      Args:
        obj: An `AutoCompositeTensor` instance.
  
      Returns:
        tensor_obj: `obj` with all internal `ResourceVariable`s converted to
          `Tensor`s.
