No tf.keras.layers.layer class ?

[minhduc66532]

I want to translate this python code to C#

class ReflectionPadding2D(tf.keras.layers.Layer):
    def __init__(self, padding=(1, 1), **kwargs):
        self.padding = tuple(padding)
        self.input_spec = [tf.keras.layers.InputSpec(ndim=4)]
        super(ReflectionPadding2D, self).__init__(**kwargs)

    def compute_output_shape(self, s):
        return (s[0], s[1] + 2 * self.padding[0], s[2] + 2 * self.padding[1], s[3])

    def call(self, x, mask=None):
        w_pad, h_pad = self.padding
        return tf.pad(x, [[0, 0], [h_pad, h_pad], [w_pad, w_pad], [0, 0]], 'REFLECT')

    def get_config(self):
        config = super().get_config().copy()
        return config

This class inherit from tf.heras.layers.layer but there is no such class in Tensorflow.NET. And i aslo notice that there is 1 class name BaseLayer in the Keras.Layers namespace. So tf.keras.layers.layer and Keras.Layers.Layer are the same class ? If so can u show me how to rewrite the custom layer above in C#. Thank you for all of your answer
