Defined in tensorflow/contrib/layers/python/layers/layers.py.

Adds a convolution3d_transpose with an optional batch normalization layer.

The function creates a variable called weights, representing the kernel, that is convolved with the input. If batch_norm_params is None, a second variable called 'biases' is added to the result of the operation.

Args:

• inputs: A 5-D Tensor of type float and shape [batch, depth, height, width, in_channels] for NDHWC data format or [batch, in_channels, depth, height, width] for NCDHW data format.
• num_outputs: Integer, the number of output filters.
• kernel_size: A list of length 3 holding the [kernel_depth, kernel_height, kernel_width] of the filters. Can be an int if both values are the same.
• stride: A list of length 3: [stride_depth, stride_height, stride_width]. Can be an int if both strides are the same. Note that presently both strides must have the same value.
• padding: One of 'VALID' or 'SAME'.
• data_format: A string. NDHWC (default) and NCDHW are supported.
• activation_fn: Activation function. The default value is a ReLU function. Explicitly set it to None to skip it and maintain a linear activation.
• normalizer_fn: Normalization function to use instead of biases. If normalizer_fn is provided then biases_initializer and biases_regularizer are ignored and biases are not created nor added. default set to None for no normalizer function
• normalizer_params: Normalization function parameters.
• weights_initializer: An initializer for the weights.
• weights_regularizer: Optional regularizer for the weights.
• biases_initializer: An initializer for the biases. If None skip biases.
• biases_regularizer: Optional regularizer for the biases.
• reuse: Whether or not the layer and its variables should be reused. To be able to reuse the layer scope must be given.
• variables_collections: Optional list of collections for all the variables or a dictionary containing a different list of collection per variable.
• outputs_collections: Collection to add the outputs.
• trainable: Whether or not the variables should be trainable or not.
• scope: Optional scope for variable_scope.

Returns:

A tensor representing the output of the operation.

Raises:

• ValueError: If 'kernel_size' is not a list of length 3.
• ValueError: If data_format is neither NDHWC nor NCDHW.
• ValueError: If C dimension of inputs is None.
