Web14 Jun 2024 · The Keras input shape is a parameter for the input layer (InputLayer). You’ll use the input shape parameter to define a tensor for the first layer in your neural network. … Webtf.Tensor.shape is equivalent to tf.Tensor.get_shape (). In a tf.function or when building a model using tf.keras.Input, they return the build-time shape of the tensor, which may be partially unknown. A tf.TensorShape is not a tensor. Use tf.shape (t) to get a tensor containing the shape, calculated at runtime. Web1 Mar 2024 · The Keras functional API is a way to create models that are more flexible than the tf.keras.Sequential API. The functional API can handle models with non-linear topology, shared layers, and even multiple inputs or outputs. The main idea is that a deep learning model is usually a directed acyclic graph (DAG) of layers. starlight liquor liberal ks
