Hi everyone, I have developed a deep-learning object-detect program based on pytorch and it works very well. Today I deploy this program on a PC, everything goes well, but the program cannot be launched. Debug and find out that, the program blocks, or halts, on importing pytorch.
Simply start a python prompt, type import torch and the prompt blocks. top command shows that CPU/memory usage is very low. Press ctrl-c cannot stop the prompt. While other library importing is fine. I have tried pycrypto and the one I wrote myself, all work but pytorch cannot.
I have deployed more than 100 times, but never meet this situation. I also tried to reinstall pytorch, from 1.6 to 1.4, torchvision from 0.7 to 0.5, still not work. No error printed, no complain shown.
Environment:

OS: centos 7.4
CUDA: 10.0
NVIDIA driver: 440.82
GPU: GTX 1660
python: 3.6

pytorch version: 1.6 and 1.4.
Any information are welcome, thanks in advance.
