# tf.ones_like(tensor, dtype=None, name=None, optimize=True)

### tf.ones_like(tensor, dtype=None, name=None, optimize=True)

Creates a tensor with all elements set to 1.

Given a single tensor (tensor), this operation returns a tensor of the same type and shape as tensor with all elements set to 1. Optionally, you can specify a new type (dtype) for the returned tensor.

For example:

# 'tensor' is [[1, 2, 3], [4, 5, 6]]
tf.ones_like(tensor) ==> [[1, 1, 1], [1, 1, 1]]


#### Args:

• tensor: A Tensor.
• dtype: A type for the returned Tensor. Must be float32, float64, int8, int16, int32, int64, uint8, complex64, complex128 or bool.
• name: A name for the operation (optional).
• optimize: if true, attempt to statically determine the shape of 'tensor' and encode it as a constant.

#### Returns:

A Tensor with all elements set to 1.
