error in ssd_demo? #11

Closed maxiaoyuelun closed 7 years ago

maxiaoyuelun commented 7 years ago

when I run the ssd_demo.m, an error occurred in vl_nnflatten.m, the dzdy has an empty matrix, and so the error in Line 31 of vl_nnflatten.m comes. below is the error image:

error: vl_nnflatten (line 31) y = reshape(dzdy{1}, sz) ;

error: dagnn.Flatten/forward (line 13) outputs{1} = vl_nnflatten(inputs{1}, obj.axis, []) ;

error: dagnn.Layer/forwardAdvanced (line 85) outputs = obj.forward(inputs, {net.params(par).value}) ;

error: dagnn.DagNN/eval (line 91) obj.layers(l).block.forwardAdvanced(obj.layers(l)) ;

error ssd_demo (line 66) net.eval({'data', im})

thank you for your attention!!!
