        for each block in the current group.
      temporal_strides: An `int` of temporal strides for the first convolution
        in this group.
      spatial_strides: An `int` stride to use for the first convolution of the
        layer. If greater than 1, this layer will downsample the input.
      block_fn: Either `nn_blocks.ResidualBlock` or `nn_blocks.BottleneckBlock`.
      block_repeats: An `int` of number of blocks contained in the layer.
      stochastic_depth_drop_rate: A `float` of drop rate of the current block
        group.
      use_self_gating: A `bool` that specifies whether to apply self-gating
        module or not.
      name: A `str` name for the block.

    Returns:
      The output `tf.Tensor` of the block layer.
