无法导入 Pytorch [WinError 126] 找不到指定的模块 [英] Cannot import Pytorch [WinError 126] The specified module could not be found

问题描述

我正在尝试在 Windows 10 上进行 Pytorch/Torchvision 的基本安装和导入.我安装了 Anaconda 并创建了一个名为 photo 的新虚拟环境.我打开 Anaconda prompt，激活环境，然后运行:

I'm trying to do a basic install and import of Pytorch/Torchvision on Windows 10. I installed a Anaconda and created a new virtual environment named photo. I opened Anaconda prompt, activated the environment, and I ran:

(photo) C:Users<user>anaconda3envs>conda install pytorch torchvision cudatoolkit=10.2 -c pytorch**

这样就成功安装了pytorch.运行 conda list 我看到:

This installed pytorch successfully. Running conda list I see:

  pytorch            pytorch/win-64::pytorch-1.5.0-py3.7_cuda102_cudnn7_0

  torchvision        pytorch/win-64::torchvision-0.6.0-py37_cu102

然后我在虚拟环境中打开一个 python 命令提示符，然后输入:

Then I open a python command prompt while in the virtual environment, and type:

打印出以下错误:

我已经卸载/重新安装了 python 和 anaconda，但仍然遇到同样的问题.感谢您的建议.

I have uninstalled/reinstalled python and anaconda but still run into the same issue. Advice appreciated.

推荐答案

参考以下链接:https://discuss.pytorch.org/t/cannot-import-torch-on-jupyter-notebook/79334

这很可能是因为您在未安装 GPU 驱动程序的系统上使用 PyTorch 的 CUDA 变体.也就是说，如果你没有Nvidia GPU卡，请按照https:/上的命令安装cpu-only包/pytorch.org.

This is most probably because you are using a CUDA variant of PyTorch on a system that doesn’t have GPU driver installed. That is to say, if you don’t have a Nvidia GPU card, please install the cpu-only package according to the commands on https://pytorch.org.

conda install pytorch torchvision cpuonly -c pytorch

conda install pytorch torchvision cpuonly -c pytorch

pip install torch==1.5.0+cpu torchvision==0.6.0+cpu -f https://download.pytorch.org/whl/torch_stable.html

pip install torch==1.5.0+cpu torchvision==0.6.0+cpu -f https://download.pytorch.org/whl/torch_stable.html
