python - 导入 PyTorch 时出错 - Python

Question

我尝试在终端中使用以下命令安装 PyTorch:

pip install http://download.pytorch.org/whl/torch-0.2.0.post1-cp27-none-macosx_10_7_x86_64.whl 

然后我在 python 中运行以下代码:

import torch
torch.__file__

并出现以下错误:

 File "/Users/brian/anaconda/lib/python2.7/site-packages/torch/__init__.py", line 48, in <module>
import torch._dl as _dl_flags

AttributeError: 'module' object has no attribute '_dl'

我试图研究这个问题，但找不到明确的答案。任何帮助将不胜感激。

编辑:这些是尝试使用以下命令重新安装 PyTorch 的结果:

pip install http://download.pytorch.org/whl/torch-0.2.0.post1-cp27-none-macosx_10_7_x86_64.whl 
pip install torchvision 

结果:

Requirement already satisfied: pyyaml in ./anaconda/lib/python2.7/site-packages (from torch==0.2.0.post1)
Requirement already satisfied: numpy in ./anaconda/lib/python2.7/site-packages (from torch==0.2.0.post1)


Requirement already satisfied: torchvision in ./anaconda/lib/python2.7/site-packages
Requirement already satisfied: pillow in ./anaconda/lib/python2.7/site-packages (from torchvision)
Requirement already satisfied: torch in ./anaconda/lib/python2.7/site-packages (from torchvision)
Requirement already satisfied: numpy in ./anaconda/lib/python2.7/site-packages (from torchvision)
Requirement already satisfied: six in ./anaconda/lib/python2.7/site-packages (from torchvision)
Requirement already satisfied: olefile in ./anaconda/lib/python2.7/site-packages (from pillow->torchvision)
Requirement already satisfied: pyyaml in ./anaconda/lib/python2.7/site-packages (from torch->torchvision)

编辑二

以下命令:

conda install pytorch torchvision cuda80 -c soumith

产生这个结果:

Fetching package metadata ...........

PackageNotFoundError: Packages missing in current channels:

   - cuda80

We have searched for the packages in the following channels:

  - https://conda.anaconda.org/soumith/osx-64
  - https://conda.anaconda.org/soumith/noarch
  - https://repo.continuum.io/pkgs/free/osx-64

Answer 1

关于http://pytorch.org/与:

• 操作系统:OSX
• 包管理器:pip
• Python:2.7
• CUDA:无

我有:

pip install http://download.pytorch.org/whl/torch-0.2.0.post1-cp27-none-macosx_10_7_x86_64.whl 
pip install torchvision 
# OSX Binaries dont support CUDA, install from source if CUDA is needed

• 您确定选择了所有正确的选项吗？
• 您是否尝试过第二个命令，pip install torchvision？

编辑

在您的日志中似乎您的 Mac 上安装了 anaconda，这意味着您应该选择 Package manager: conda 而不是点。

在这种情况下，您应该删除使用 pip 安装的软件包:

pip uninstall torch

并使用 anaconda 命令代替:

• 操作系统:OSX
• 包管理器:conda
• Python:2.7
• CUDA:无

运行命令:

conda install pytorch torchvision -c soumith
