self.length in DeformConvPack_d

[mfaizan-ai]

Thank you for the excellent work! I noticed that self.length is checked for values 1 and 2, but in the case of THW, shouldn’t it be 3? Could you clarify this?

Additionally, could you explain the meanings of DeformConv, DeformConv_d, DeformConvPack, and DeformConvPack_d? When should each of these be used?

see issue #12.

@XinyiYing self.length is defined for dimension 2 and 1, however, the dimensions for 'hwd' is 3. I don't understand that.

"DeformConvPack" is used for D3D deforming in three dimensions (using its own offsets)
"DeformConv" is used for D3D deform in three dimensions (using extra offsets)

"DeformConvPack_d" is used for D3D deforming in option 2 or 1 dimensions (using its own offsets)
"DeformConv_d" is used for D3D deforming in option 2 or 1 dimensions (using extra offsets)

Please refer to ./dcn/test.py for example usage.
