Slide 10.4: Creating a tensor

TensorFlow.js Tutorial (Cont.)

Creating a Tensor
The main data type in TensorFlow is the tensor, which is created from any N-dimensional array with the tf.tensor() function:

<html> <script src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs"></script> <body> <div id="demo" /> <script type="text/javascript"> const myArr = [[1, 2], [3, 4]]; const tensorA = tf.tensor(myArr); document.getElementById("demo").innerHTML = tensorA; </script> </body> </html>


<html> <script src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs"></script> <body> <div id="demo" /> <script type="text/javascript"> const tensorA = tf.tensor([[1, 2], [3, 4], [5, 6]]); document.getElementById("demo").innerHTML = tensorA; </script> </body> </html>

Tensor Shape
A tensor can also be created from an array and a shape parameter.


<html> <script src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs"></script> <body> <div id="demo" /> <script type="text/javascript"> const myArr = [1, 2, 3, 4]; const shape = [2, 2]; const tensorA = tf.tensor(myArr, shape); document.getElementById("demo").innerHTML = tensorA; </script> </body> </html>


<html> <script src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs"></script> <body> <div id="demo" /> <script type="text/javascript"> const tensorA = tf.tensor([1, 2, 3, 4], [2, 2]); document.getElementById("demo").innerHTML = tensorA; </script> </body> </html>


<html> <script src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs"></script> <body> <div id="demo" /> <script type="text/javascript"> const myArr = [[1, 2], [3, 4]]; const shape = [2, 2]; const tensorA = tf.tensor(myArr, shape); document.getElementById("demo").innerHTML = tensorA; </script> </body> </html>
