cpu模式下的pix2pixHD非法指令

Question

我正在测试pix2pixHD。我没有GPU。我正在使用pytorch==0.4.1。我正在使用以下命令运行cityscape模型的测试：

python test.py --name label2city_1024p --netG local --ngf 32 --gpu_ids -1 --resize_or_crop none

但是我得到了Illegal instruction (core dumped)。我用gdb做了回溯发现：

#0  0x00007fcd623175e6 in THFloatVector_normal_fill_AVX2 () from /home/momen/nvidia_vid2vid/lib/python3.6/site-packages/torch/lib/libcaffe2.so

如何解决这个问题？欢迎任何形式的帮助。谢谢。你知道吗

其他信息： 我尝试了py-bt，问题出现在第一层的m.weight.data.normal_(0.0, 0.02)。你知道吗
