Assertion error about targets.shape[3] during Backprop.

[neuralix]

Hi Nitish,

I met this kind of error when i run train_convnet.
"train_convnet: cudamat_conv_gemm.cu:691: void convOutpGemm(cudamat, cudamat_, cudamat*, Shape4D, Shape4D, Shape4D, ConvDesc, float, float, bool): Assertion `num_input_channels * filterModuleMult == num_input_channels3Mult' failed."

after analyzing, I found the error occur a part below.

void ConvEdge::ComputeOuter(Matrix& input, Matrix& deriv_output) {
...
if (partial_sum_locs > 1) {
...
} else {
...
}

dt_temp(:targets)'s element shape[3] is strange...
when I change like it,
'if (partial_sum_locs > 1) { --> if (0) {'
the problem was not generated.

I got this error too.
