Error running main_ADMM_CSNet_test.m

[olgudel]

When running each line of main_ADMM_CSNet_test.m in CSNet-Image, I get an error on the following line:

[re_LOss, re_PSnr , re_SSim, rec_image ]= loss_with_gradient_single_before(x0, im_ori, net, mask.picks, mask.perm);

Attempt to execute SCRIPT vl_nnconv as a function:
C:\Users\Oliver\Desktop\ADMM-CSNet-master\matlab\vl_nnconv.m
Error in dagnn.Conv2D/forward (line 10)
outputs{1} = vl_nnconv(inputs{1}, params{1}, params{2}, 'pad', pad1);
Error in dagnn.Layer/forwardAdvanced (line 85)
outputs = obj.forward(inputs, {net.params(par).value}) ;
Error in dagnn.DagNN/eval (line 91)
obj.layers(l).block.forwardAdvanced(obj.layers(l)) ;
Error in loss_with_gradient_single_before (line 41)
net.eval(inputs) ;

Is there a particular way to resolve this to test the code? I'm running this on MATLAB R2018a.
