  -i INPUT_NAMES, --input_names INPUT_NAMES
        List of input OP names. All input OPs of the model must be specified.
        The order is unspecified, but must match the order specified for input_shapes.
        e.g.
        --input_names "input.A" \
        --input_names "input.B" \

        List of input OP shapes. All input OPs of the model must be specified.
        The order is unspecified, but must match the order specified for input_names.
        e.g.
        --input_shapes 1 3 "H" "W" \
        --input_shapes "N" 3 "H" "W" \
        --input_shapes "-1" 3 480 640

  -o OUTPUT_NAMES, --output_names OUTPUT_NAMES
        List of output OP names. All output OPs of the model must be specified.
        The order is unspecified, but must match the order specified for output_shapes.
        e.g.
        --output_names "output.a" \
        --output_names "output.b" \
        --output_names "output.c"

  -os OUTPUT_SHAPES [OUTPUT_SHAPES ...], --output_shapes OUTPUT_SHAPES [OUTPUT_SHAPES ...]
        List of input OP shapes. All output OPs of the model must be specified.

        e.g.
        --output_shapes 1 3 "H" "W" \
        --output_shapes "N", 3, "H", "W" \
        --output_shapes "-1" 3 480 640
