I am trying to import and load a trained keras cycleGAN model into tensorflowjs and angular typescript.

but i ran into the error that says “ERROR Error: Uncaught (in promise): Error: Unknown layer: InstanceNormalization”

I googled and tried implementing my own custom layer as a .js file:

```
import * as tf from'@tensorflow/tfjs';
class InstanceNormalization extends tf.layers.Layer {
epsilon = 1e-7;
gamma;
beta;
constructor() {
super({});
}
build(input_shape) {
let shape = tf.tensor(input_shape);
// initialize gamma
this.gamma = this.addWeight(
'gamma',
shape,
undefined,
'ones',
undefined,
true,
);
// initialize beta
this.beta = this.addWeight(
'beta',
shape,
undefined,
'zeros',
undefined,
true,
)
}
call(inputs, kwargs) {
this.invokeCallHook(inputs, kwargs);
let mean = tf.math.reduce_mean(inputs, axis=[-1], keepdims=true);
let variance = tf.math.reduce_mean(tf.math.square(inputs - mean), axis=[-1], keepdims=true);
let std = tf.math.sqrt(variance + this.epsilon);
let outputs = (inputs - mean) / std;
outputs = outputs * this.gamma;
outputs = outputs + this.beta;
return outputs;
}
static get className() {
return 'InstanceNormalization';
}
}
tf.serialization.registerClass(InstanceNormalization);
export function instancenormalization() {
return new InstanceNormalization();
}
```

the above effort did not resolve the issue where the error message still persisted.
