Function prod

Computes the product of elements across dimensions of a tf.Tensor.

Reduces the input along the dimensions given in axes. Unless keepDims is true, the rank of the tf.Tensor is reduced by 1 for each entry in axes. If keepDims is true, the reduced dimensions are retained with length 1. If axes has no entries, all dimensions are reduced, and a tf.Tensor with a single element is returned.

const x = tf.tensor1d([1, 2, 3]);

x.prod().print();  // or tf.prod(x)
Copy

const x = tf.tensor2d([1, 2, 3, 4], [2, 2]);

const axis = 1;
x.prod(axis).print();  // or tf.prod(x, axis)
Copy
