Notes

If you meet errors about Embedding Layer, try fix the compute_mask function.

    def compute_mask(self, inputs, mask=None):
        if not self.mask_zero:
            return None
        else:
            # return K.not_equal(inputs, 0)
            mask = K.repeat(K.not_equal(inputs, 0), self.output_dim)
            mask = tf.transpose(mask, [0,2,1])
            return mask
