[FIXED] Tensorflow js, getting error while using matMul

Issue

let tensor1 = tf.tensor(m1);
let tensor2 = tf.tensor(m2);
console.log(tensor1.shape, tensor2.shape)
result = tf.matMul(tensor1, tensor2)

The output of shapes are => [ 6890, 3, 10 ] [ 10 ]

While trying to use matMul this is the error => Error: Error in matMul: inner shapes (10) and (undefined) of Tensors with shapes 6890,3,10 and 10 and transposeA=false and transposeB=false must match.

The same multiplication works fine in python using numpy's matmul.

Solution

Maybe something like this:

let tensor1 = tf.randomNormal([6890, 3, 10]);
let tensor2 = tf.randomNormal([10]).expandDims(-1);
result = tf.matMul(tensor1, tensor2).squeeze(-1)
console.log(result.shape)

[6890,3]
