Web23 jan. 2024 · My expectation would be that when I create a convolutional layer, I would have to specify a filter or set of filters to apply to the input. But the three samples I have found all create a convolutional layer like this: model.add (Convolution2D (nb_filter = 32, nb_row = 3, nb_col = 3, border_mode='valid', input_shape=input_shape)) Webfor layer in filter (lambda x: 'conv' in x.name, model.layers): weights_shape, bias_shape = map (lambda x: x.shape, layer.get_weights ()) Then you can use layer.set_weights () with the values you want, since you know the correct shape. Let's say 0.12345.
