    This module implements the "SAME" padding mode for ConvTranspose2d as in Tensorflow.
    A tensor with width w_in, feed it to ConvTranspose2d(ci, co, kernel, stride), the width of output tensor T_nopad:
        w_nopad = (w_in - 1) * stride + kernel
    If we use padding, i.e., ConvTranspose2d(ci, co, kernel, stride, padding, output_padding), the width of T_pad:
        w_pad = (w_in - 1) * stride + kernel - (2*padding - output_padding) = w_nopad - (2*padding - output_padding)
    Yes, in ConvTranspose2d, more padding, the resulting tensor is smaller, i.e., the padding is actually deleting row/col.
    If `pad`=(2*padding - output_padding) is odd, Pytorch deletes more columns in the left, i.e., the first ceil(pad/2) and
    last `pad - ceil(pad/2)` columns of T_nopad are deleted to get T_pad.
    In contrast, Tensorflow deletes more columns in the right, i.e., the first floor(pad/2) and last `pad - floor(pad/2)`
    columns are deleted.
    For the height, Pytorch deletes more rows at top, while Tensorflow at bottom.
    In practice, we usually want `w_pad = w_in * stride` or `w_pad = w_in * stride - 1`, i.e., the "SAME" padding mode
    in Tensorflow. To determine the value of `w_pad`, we should pass it to this function.
    So the number of columns to delete:
        pad = 2*padding - output_padding = w_nopad - w_pad
    If pad is even, we can directly set padding=pad/2 and output_padding=0 in ConvTranspose2d.
    If pad is odd, we can use ConvTranspose2d to get T_nopad, and then delete `pad` rows/columns by
    ourselves.
    This module should be called after the ConvTranspose2d module with shared kernel_size and stride values.
