tf.fill

TensorFlow 2 version

View source on GitHub

Creates a tensor filled with a scalar value.

tf.fill(
    dims, value, name=None
)

This operation creates a tensor of shape dims and fills it with value.

For example:

# Output tensor has shape [2, 3].
fill([2, 3], 9) ==> [[9, 9, 9]
                     [9, 9, 9]]

tf.fill differs from tf.constant in a few ways:

• tf.fill only supports scalar contents, whereas tf.constant supports Tensor values.
• tf.fill creates an Op in the computation graph that constructs the actual Tensor value at runtime. This is in contrast to tf.constant which embeds the entire Tensor into the graph with a Const node.
• Because tf.fill evaluates at graph runtime, it supports dynamic shapes based on other runtime Tensors, unlike tf.constant.
