Question

我已经在Windows 8上安装了Anaconda，之后使用PyTorch完成了安装。但是在导入火炬时会出错。

进口火炬

  AttributeError                            Traceback (most recent

376             func.__name__ = name_or_ordinal


AttributeError: function 'AddDllDirectory' not found

另外，当我使用以下命令时，它也显示了pytorch Anaconda命令提示符。

(base) C:\Users\rk88>conda list pytorch

# packages in environment at I:\ProgramData\Anaconda3:

#

# Name                    Version                   Build  Channel

pytorch                   1.0.1           py3.7_cuda100_cudnn7_1    
PyTorch

如果您之前遇到过此问题，任何人都可以帮助我解决该问题。

谢谢

在anaconda提示中尝试以下内容

conda create -n <env_name>python=3.6

conda activate <env_name>

conda install pytorch-cpu torchvision-cpu -c pytorch

如果您使用的是GPU

 conda install pytorch torchvision cudatoolkit=9.0 -c pytorch

请参阅https://pytorch.org/

Pytorch已安装，但是在导入时出现错误
