Flattens an input


Flatten a given input, does not affect the batch size.


  data_format = NULL,
  input_shape = NULL,
  dtype = NULL,
  name = NULL,
  trainable = NULL,
  weights = NULL



What to compose the new Layer instance with. Typically a Sequential model or a Tensor (e.g., as returned by layer_input()). The return value depends on object. If object is:

  • missing or NULL, the Layer instance is returned.

  • a Sequential model, the model with an additional layer is returned.

  • a Tensor, the output tensor from layer_instance(object) is returned.


A string. one of channels_last (default) or channels_first. The ordering of the dimensions in the inputs. The purpose of this argument is to preserve weight ordering when switching a model from one data format to another. channels_last corresponds to inputs with shape ⁠(batch, ..., channels)⁠ while channels_first corresponds to inputs with shape ⁠(batch, channels, ...)⁠. It defaults to the image_data_format value found in your Keras config file at ⁠~/.keras/keras.json⁠. If you never set it, then it will be "channels_last".


Input shape (list of integers, does not include the samples axis) which is required when using this layer as the first layer in a model.


The data type expected by the input, as a string (float32, float64, int32...)


An optional name string for the layer. Should be unique in a model (do not reuse the same name twice). It will be autogenerated if it isn't provided.


Whether the layer weights will be updated during training.


Initial weights for layer.
