Really Annoying for trying to understand spconv2d, will you please give us a detailed example on the input of [4,3,128,128] (NCHW) up channel to (4,16,128,128) ) #702

did you solve it? I can not figure out how to convert a [batch_size, 64, 512,512] to a sparse 2D tensor that I can pass to sparse 2D convs
