i want to use eval.py but have some error

[sherrygux]

I have use eval.py but have some error message, and ap is all 0. Message is like :SSD.Pytorch/layers/box_utils.py:228: UserWarning: An output with one or more elements was resized since it had shape [192], which does not match the required output shape [172]. This behavior is deprecated, and in a future PyTorch release outputs will not be resized unless they have zero elements. You can explicitly reuse an out tensor t by resizing it, inplace, to zero elements with t.resize_(0). (Triggered internally at ../aten/src/ATen/native/Resize.cpp:26.)
torch.index_select(x1, 0, idx, out=xx1)
