Webtf.keras.layers.Conv1D.set_weights set_weights(weights) Sets the weights of the layer, from Numpy arrays. Arguments: weights: a list of Numpy arrays. The number of arrays and their shape must match number of the dimensions of the weights of the layer (i.e. it should match the output of get_weights).
