| Args | |
|---|---|
input | A list of Tensor objects. A list of input tensors whose types are T. |
cond | A function decorated with @Defun. A function takes 'input' and returns a tensor. If the tensor is a scalar of non-boolean, the scalar is converted to a boolean according to the following rule: if the scalar is a numerical value, non-zero means True and zero means False; if the scalar is a string, non-empty means True and empty means False. If the tensor is not a scalar, non-emptiness means True and False otherwise. |
body | A function decorated with @Defun. A function that takes a list of tensors and returns another list of tensors. Both lists have the same types as specified by T. |
output_shapes | An optional list of shapes (each a tf.TensorShape or list of ints). Defaults to []. |
parallel_iterations | An optional int. Defaults to 10. |
name | A name for the operation (optional). |
| Returns | |
|---|---|
A list of Tensor objects. Has the same type as input. |
