I am trying to use a deconvolution layer or a Conv2DTranspose, but this error occurs.
self.up_sample = nn.Conv2DTranspose(c, kernel_size=3, strides=2, padding=1, groups=c)
src/operator/nn/deconvolution.cc:192: Check failed: dshape_nchw % param_.num_group == 0U (255 vs. 0) : input num_filter must divide group size
I checked c right before the line and it was not 255 but 320. Also c divides c in any case. Here my understanding is that dshape_nchw stands for the value of channel. Am I understanding the error in a wrong way? What should I do to avoid the error?
