    conv_ndims,

)

Construct ConvLSTMCell.

Args:

  • conv_ndims: Convolution dimensionality (1, 2 or 3).
  • input_shape: Shape of the input as int tuple, excluding the batch size.
  • output_channels: int, number of output channels of the conv LSTM.
  • kernel_shape: Shape of kernel as an int tuple (of size 1, 2 or 3).
  • use_bias: (bool) Use bias in convolutions.
  • skip_connection: If set to True, concatenate the input to the output of the conv LSTM. Default: False.
  • forget_bias: Forget bias.
  • initializers: Unused.
  • name: Name of the module.

Raises:

  • ValueError: If skip_connection is True and stride is different from 1 or if input_shape is incompatible with conv_ndims.

DEPRECATED FUNCTION

output_size

Integer or TensorShape: size of outputs produced by this cell.

scope_name

state_size

size(s) of state(s) used by this cell.

It can be represented by an Integer, a TensorShape or a tuple of Integers or TensorShapes.

get_initial_state(
    inputs=None,
    batch_size=None,
    dtype=None
)

tf.contrib.rnn.ConvLSTMCell.zero_state

View source

zero_state(
    batch_size,
    dtype
)

Return zero-filled state tensor(s).

Args:

  • batch_size: int, float, or unit Tensor representing the batch size.
  • dtype: the data type to use for the state.

Returns:

If state_size is an int or TensorShape, then the return value is a N-D tensor of shape [batch_size, state_size] filled with zeros.

If state_size is a nested list or tuple, then the return value is a nested list or tuple (of the same structure) of 2-D tensors with the shapes [batch_size, s] for each s in state_size.
