Anaconda 与 Cuda 9.0 的集成显示不兼容的包错误

Question

我正在尝试在 Windows 10 中 使用NVIDIA-SMI: 445.75安装CUDA 9.0。

我的Cuda 9.0安装成功，如图Command-prompt

*(DL) C:\Users\User>nvcc --version    
nvcc: NVIDIA (R) Cuda compiler driver    
Copyright (c) 2005-2017 NVIDIA Corporation    
Built on Fri_Sep__1_21:08:32_Central_Daylight_Time_2017    
**Cuda compilation tools, release **9.0**, V9.0.176***

(1) 我下载了cudnn-9.0-windows10-x64-v7.zip，解压了它，然后将它移到了安装 Cuda 时创建的文件夹中。

(2) 在Anaconda的terminal提示下， 我输入.
conda install pytorch=1.1.0 torchvision=0.3.0 cudatoolkit=9.0 –c pytorch

但是，Anaconda 提示给出以下错误

**Error messages**

UnsatisfiableError: The following specifications were found to be incompatible with the existing python installation in your environment:    

Specifications:    

  - pytorch=1.1.0 -> python[version='>=3.5,<3.6.0a0|>=3.6,<3.7.0a0|>=3.7,<3.8.0a0']

Your python: python=3.8    

如果 python 位于链的最左侧，那就是您要求的版本。
当 python 出现在右边时，这表明左边的东西在某种程度上不适用于你所限制的 python 版本。请注意，除非您明确指定，否则 conda 不会将您的 Python 版本更改为不同的次要版本。

发现以下规格彼此不兼容：

Answer 1

我解决了这个问题如下。

1. 通过在开始菜单中搜索来打开 Anaconda Powershell Prompt。
2. 然后运行conda install -c anaconda tensorflow-gpu命令。
3. 可能会要求您接受。

最终tensorflow-gpu列在已安装列表中。
