tf.contrib.autograph.stack

tf.contrib.autograph.stack(
    list_or_tensor,
    element_dtype=None,
    strict=True
)

Defined in tensorflow/contrib/autograph/lang/special_functions.py.

Stacks the input, if it admits the notion of stacking.

For example, a list of tensors can be stacked into a larger tensor. This function is similar to tf.stack, but it accepts non-lists and lists of non-tensors as arguments. In the latter case, the function does nothing.

Args:

  • list_or_tensor: Any
  • element_dtype: tf.DType, optional dtypedtype for the elements in the list. Required if the input is stackable, and the list is untyped.
  • strict: bool, if True an error is raised if the input is not stackable. Otherwise the function is a no-op.

Returns:

Any, if the input is stackable, the result will be a tf.Tensor. Otherwise, if strict=False, the result will be list_or_tensor.

Raises:

  • ValueError: if strict=True and the input is not stackable.
