tf.contrib.autograph.stack

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

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

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.
