Computes the gradients of depthwise convolution with respect to the filter.

Args:

• input: A Tensor. Must be one of the following types: float32, float64. 4-D with shape based on data_format. For example, if data_format is 'NHWC' then input is a 4-D [batch, in_height, in_width, in_channels] tensor.
• filter_sizes: A Tensor of type int32. An integer vector representing the tensor shape of filter, where filter is a 4-D [filter_height, filter_width, in_channels, depthwise_multiplier] tensor.
• out_backprop: A Tensor. Must have the same type as input. 4-D with shape based on data_format. For example, if data_format is 'NHWC' then out_backprop shape is [batch, out_height, out_width, out_channels]. Gradients w.r.t. the output of the convolution.
• strides: A list of ints. The stride of the sliding window for each dimension of the input of the convolution.
• padding: A string from: "SAME", "VALID". The type of padding algorithm to use.
• data_format: An optional string from: "NHWC", "NCHW". Defaults to "NHWC". Specify the data format of the input and output data. With the default format "NHWC", the data is stored in the order of: [batch, height, width, channels]. Alternatively, the format could be "NCHW", the data storage order of: [batch, channels, height, width].
• name: A name for the operation (optional).

Returns:

A Tensor. Has the same type as input. 4-D with shape [filter_height, filter_width, in_channels, out_channels]. Gradient w.r.t. the filter input of the convolution.
