Naturally, this also applies to Sequential models. Layer.weights # Now it has weights, of shape (4, 3) and (3,) Of the weights depends on the shape of the inputs: # Call layer on a test input It creates its weights the first time it is called on an input, since the shape This, initially, it has no weights: layer = layers.Dense(3) In order to be able to create their weights. Generally, all layers in Keras need to know the shape of their inputs Model.add(layers.Dense(4, name='layer3')) Model.add(layers.Dense(3, activation='relu', name='layer2')) Model.add(layers.Dense(2, activation='relu', name='layer1')) model = keras.Sequential(name='my_sequential') This is useful to annotate TensorBoard graphs model.pop()Īlso note that the Sequential constructor accepts a name argument, just likeĪny layer or model in Keras. Note that there's also a corresponding pop() method to remove layers:Ī Sequential model behaves very much like a list of layers. Model.add(layers.Dense(3, activation='relu')) Model.add(layers.Dense(2, activation='relu')) You can also create a Sequential model incrementally via the add() method: model = keras.Sequential() Its layers are accessible via the layers attribute: model.layers You can create a Sequential model by passing a list of layers to the Sequential

Any of your layers has multiple inputs or multiple outputs.

Your model has multiple inputs or multiple outputs.

Layer2 = layers.Dense(3, activation='relu', name='layer2')Ī Sequential model is not appropriate when: Layer1 = layers.Dense(2, activation='relu', name='layer1') Is equivalent to this function: # Create 3 layers Layers.Dense(3, activation='relu', name='layer2'), Layers.Dense(2, activation='relu', name='layer1'), Schematically, the following Sequential model: # Define Sequential model with 3 layers Where each layer has exactly one input tensor and one output tensor. If you would like to use Nvidia GPU with TensorRT, please make sure the missing libraries mentioned above are installed properly.Ī Sequential model is appropriate for a plain stack of layers 02:19:19.903396: W tensorflow/compiler/tf2tensorrt/utils/py_:38] TF-TRT Warning: Cannot dlopen some TensorRT libraries. 02:19:19.903386: W tensorflow/compiler/xla/stream_executor/platform/default/dso_:64] Could not load dynamic library 'libnvinfer_plugin.so.7' dlerror: libnvinfer_plugin.so.7: cannot open shared object file: No such file or directory Conditions and other risk factors that may be associated with severe illness and death are listed below.02:19:19.903296: W tensorflow/compiler/xla/stream_executor/platform/default/dso_:64] Could not load dynamic library 'libnvinfer.so.7' dlerror: libnvinfer.so.7: cannot open shared object file: No such file or directory Having underlying medical conditions may also increase one’s risk for severe illness from COVID-19.
