Mac：使用pip3安装pytorch后import报错：Reason: image not found

• MacOS Mojava 10.14.5
• python 3.6.2
• pip 19.1.1
• torch-1.1.0
• torchvision-0.3.0

使用如下命令安装pytorch：

pip3 install torch torchvision

安装成功后导入模块失败：

>>> import torch
Traceback (most recent call last):
  File "", line 1, in 
  File "/Users/chao/.pyenv/versions/3.6.2/lib/python3.6/site-packages/torch/__init__.py", line 79, in 
    from torch._C import *
ImportError: dlopen(/Users/chao/.pyenv/versions/3.6.2/lib/python3.6/site-packages/torch/_C.cpython-36m-darwin.so, 9): Library not loaded: /usr/local/opt/libomp/lib/libomp.dylib

• 解决方案：首先确保你的Mac已经安装过homebrew，然后一条命令解决问题：

brew install libomp
