在 Python 中导入 Torch 时如何解决 OSError [英] How to solve the OSError while Importing torch in Python

问题描述

信息:

• 操作系统:Windows 8.1 64 位
• Python:3.7.3 64 位
• Anaconda:64 位

议程:

确保 python -c "import torch" 工作没有任何错误.

To make sure python -c "import torch" works without any errors.

过程:

我已经使用 conda create -n myenv

在此之后，我非常困难地进一步安装了conda install pytorch torchvision cudatoolkit -c pytorch

After which with great difficulty I have further installed conda install pytorch torchvision cudatoolkit -c pytorch

执行上述命令时，由于HTTPRequest失败，中途中断

When the above command was executed, it was interrupted midway due to HTTPRequest failure

在几次这样的失败之后，我使用 conda install pytorch -c pytorch

After several such failures, I have installed pytorch using conda install pytorch -c pytorch

当我输入 python -c "import torch" 我得到如下所示的 OSError

When I type python -c "import torch" I get OSError like the one below

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "C:\Users\sanpj\.conda\envs\myenv\lib\site-packages\torch\__init__.py", line 42, in <module>
    import numpy as _np  # noqa: F401
  File "C:\Users\sanpj\AppData\Roaming\Python\Python37\site-packages\numpy\__init__.py", line 142, in <module>
    from . import core
  File "C:\Users\sanpj\AppData\Roaming\Python\Python37\site-packages\numpy\core\__init__.py", line 23, in <module>
    WinDLL(os.path.abspath(filename))
  File "C:\Users\sanpj\.conda\envs\myenv\lib\ctypes\__init__.py", line 356, in __init__
    self._handle = _dlopen(self._name, mode)
OSError: [WinError 193] %1 is not a valid Win32 application

但输出不应如此.

当我输入 python 时，我得到一些如下所述的信息

When I type in python, I get some information as mentioned below

Python 3.7.3 (default, Apr 24 2019, 15:29:51) [MSC v.1915 64 bit (AMD64)] :: Anaconda, Inc. on win32
Type "help", "copyright", "credits" or "license" for more information.

推荐答案

解决了！

实际上，我降级到旧版本的torch、torchvision &也麻木了.这实际上解决了这个问题.

Actually, I downgraded to older versions of torch, torchvision & numpy as well. That actually solved this issue.
