安装pytorch==1.7.0
安装命令：
`pip install pytorch==1.7.0`
报错：
`ERROR: No matching distribution found for pytorch==1.7.0`
去pytorch看了一下官方教程：
在对应的版本最好使用的命令应该是：
v1.7.0
Conda
OSX
# conda
conda install pytorch==1.7.0 torchvision==0.8.0 torchaudio==0.7.0 -c pytorch
Linux and Windows
# CUDA 9.2
conda install pytorch==1.7.0 torchvision==0.8.0 torchaudio==0.7.0 cudatoolkit=9.2 -c pytorch
# CUDA 10.1
conda install pytorch==1.7.0 torchvision==0.8.0 torchaudio==0.7.0 cudatoolkit=10.1 -c pytorch
# CUDA 10.2
conda install pytorch==1.7.0 torchvision==0.8.0 torchaudio==0.7.0 cudatoolkit=10.2 -c pytorch
# CUDA 11.0
conda install pytorch==1.7.0 torchvision==0.8.0 torchaudio==0.7.0 cudatoolkit=11.0 -c pytorch
# CPU Only
conda install pytorch==1.7.0 torchvision==0.8.0 torchaudio==0.7.0 cpuonly -c pytorch
Wheel
OSX
pip install torch==1.7.0 torchvision==0.8.0 torchaudio==0.7.0
Linux and Windows
# CUDA 11.0
pip install torch==1.7.0+cu110 torchvision==0.8.0+cu110 torchaudio==0.7.0 -f https://download.pytorch.org/whl/torch_stable.html
# CUDA 10.2
pip install torch==1.7.0 torchvision==0.8.0 torchaudio==0.7.0
# CUDA 10.1
pip install torch==1.7.0+cu101 torchvision==0.8.0+cu101 torchaudio==0.7.0 -f https://download.pytorch.org/whl/torch_stable.html
# CUDA 9.2
pip install torch==1.7.0+cu92 torchvision==0.8.0+cu92 torchaudio==0.7.0 -f https://download.pytorch.org/whl/torch_stable.html
# CPU only
pip install torch==1.7.0+cpu torchvision==0.8.0+cpu torchaudio==0.7.0 -f https://download.pytorc
于是我使用了安装命令：
`pip install torch==1.7.0 torchvision==0.8.0 torchaudio==0.7.0 Collecting torch==1.7.0`
但是再度遇到了报错：
`ERROR: torch has an invalid wheel, .dist-info directory not found`
不得不再度查询解决方法，从官网上查找相关问题以及解决方法：官方网站上有关 CUDA 版本的更多详细信息
可以尝试以下命令：
如果您不需要 CUDA 安装
pip install torch==1.7.0+cpu torchvision==0.8.1+cpu torchaudio===0.7.0 -f https://download.pytorch.org/whl/torch_stable.html
如果您需要安装 CUDA
pip install torch===1.7.0 torchvision===0.8.1 torchaudio===0.7.0 -f https://download.pytorch.org/whl/torch_stable.html
If you do not need a CUDA installation
pip install torch==1.7.0+cpu torchvision==0.8.1+cpu torchaudio===0.7.0 -f https://download.pytorch.org/whl/torch_stable.html
If you fo need a CUDA installation
pip install torch===1.7.0 torchvision===0.8.1 torchaudio===0.7.0
