TensorFlow – How to create a tensor with all elements set to one
• Last Updated : 01 Aug, 2020

TensorFlow is open-source Python library designed by Google to develop Machine Learning models and deep learning  neural networks.

Methods Used:

• tf.ones: This methods accepts the shape and type and returns a tensor of give shape and type having all values set to 1.
• tf.fill: This method accepts shape, value and type and returns a tensor of given shape and type having all values set to value.

Example 1: This example uses ones() method to create a tensor with all elements set to one.

## Python3

 `# importing the library``import` `tensorflow as tf`` ` `# Generating a Tensor of shape (2, 3)``res ``=` `tf.ones(shape ``=` `(``2``, ``3``))`` ` `# Printing the resulting Tensors``print``(``"Res: "``, res )`

Output:

```
Res:  tf.Tensor(
[[1. 1. 1.]
[1. 1. 1.]], shape=(2, 3), dtype=float32)
```

Example 2: This example uses fill() method with value = 1 to create a tensor with all elements set to one.

## Python3

 `# importing the library``import` `tensorflow as tf`` ` `# Generating a Tensor of shape (2, 3)``res ``=` `tf.fill(dims ``=` `(``2``, ``3``), value ``=` `1``)`` ` `# Printing the resulting Tensors``print``(``"Res: "``, res )`

Output:

```
Res:  tf.Tensor(
[[1 1 1]
[1 1 1]], shape=(2, 3), dtype=int32)

```
