Custom convolution kernel

[cama36]

Hello, I noticed that the convolution kernel size of the engine that supports spconv is not variable. For example, it now supports 128 * 128, 16 * 32, 32 * 32, etc. In addition, you have also open-sourced the relevant code? I am sorry that I am a novice in this. For example, if I want to customize the size of the convolution kernel, such as 6 * 32, can I build it myself? Is there anything I can learn in this regard? Thank you very much for your help, which will benefit me a lot. Thank you.
