form oT x oH x oW. Can be a tuple (oT, oH, oW) or a single
        number oH for a square image oH x oH x oH
  * **output_ratio** (*Union**[**float**, **Tuple**[**float**,
    **float**, **float**]**]*) -- If one wants to have an output
    size as a ratio of the input size, this option can be given.
    This has to be a number or tuple in the range (0, 1)

  * **return_indices** (*bool*) -- if "True", will return the
    indices along with the outputs. Useful to pass to
    "nn.MaxUnpool3d()". Default: "False"

Shape:
      * Input: (N, C, T_{in}, H_{in}, W_{in}) or (C, T_{in}, H_{in},
        W_{in}).
  * Output: (N, C, T_{out}, H_{out}, W_{out}) or (C, T_{out},
    H_{out}, W_{out}), where (T_{out}, H_{out},
    W_{out})=\text{output\_size} or (T_{out}, H_{out},
    W_{out})=\text{output\_ratio} \times (T_{in}, H_{in}, W_{in})
