ggml_conv_2d problem

[weishuai-GitHub]

I have a problem when i compute ggml_conv_2d.
ggml_tensor *output = ggml_conv_2d(gctx,weight, input,stride,stride, 0, 0, 1, 1);
the inputs is:

weight->ne[0]: 1792
weight->ne[1]: 3
weight->ne[2]: 14
weight->ne[3]: 14
input->ne[0]: 1
input->ne[1]: 3
input->ne[2]: 14
input->ne[3]: 224

the output is:

output->ne[0]: -126
output->ne[1]: 1
output->ne[2]: 14
output->ne[3]: 224

I don’t know why the results of the convolution are like this？
In addition, in ggml_im2col , why is a-> ne [2] == b-> ne [2]?
