【问题描述】：

我正在尝试导入torch，但遇到了下一个问题：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/torch/__init__.py", line 66, in <module>
    import torch._dl as _dl_flags
ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/torch/_dl.so, 2): no suitable image found.  Did find:
    /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/torch/_dl.so: mach-o, but wrong architecture
    /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/torch/_dl.so: mach-o, but wrong architecture

有人知道我该如何解决这个问题吗？谢谢：）

/usr/lib/libstdc++.6.dylib: mach-o, but wrong architecture的可能重复
你是如何安装pytorch的？它是否支持 MacOS 或您的 Python 版本？
@GregEremeev 所以我需要为此格式化我的电脑？
@HoriaComan pip install torch torchvision。我使用的是 python 2.7，所以这是正确的版本
@chengal 当然！赶快行动，以免为时已晚！

【解决方案1】：

这样试试：

mkdir test_torch
cd test_torch
python3 -m venv .venv
source .venv/bin/activate
pip install torch torchvision
python3

>>> import torch

为我工作。 MacOS 10.13.4、Python 3.6.4

或者这样：

mkdir test_torch
cd test_torch
virtualenv .venv
source .venv/bin/activate
pip install --upgrade pip
pip install torch torchvision
python2

>>> import torch

为我工作。 MacOS 10.13.4、Python 2.7.10

如果你不需要使用torch那么你可以只安装torchvision

pip install --no-deps torchvision

我使用的是python 2.7..所以我必须删除3？
@chengal 我已经为 Python2.x 添加了解决方案。试试看。
@chengal brew install virtualenv
Error: No available formula with the name "virtualenv" ==> Searching for a previously deleted formula (in the last month)... Warning: homebrew/core is shallow clone. To get complete history run: git -C "$(brew --repo homebrew/core)" fetch --unshallow
Error: No previously deleted formula found. ==> Searching for similarly named formulae... ==> Searching local taps... These similarly named formulae were found: pyenv-virtualenv ✔ pyenv-virtualenvwrapper ✔ To install one of them, run (for example): brew install pyenv-virtualenv ✔ ==> Searching taps... ==> Searching taps on GitHub... Error: No formulae found in taps.

【解决方案2】：

试试

brew install libomp

应该解决问题
