Warning: Unless you have a very specific reason not to, just follow the official installation instructions from https://pytorch.org. They are far more likely to be accurate and up-to-date.
警告：除非您有非常具体的理由不这样做，否则只需按照https://pytorch.org的官方安装说明进行操作即可。它们更有可能是准确和最新的。
Here is how to install the PyTorch package from the official channel, on Windows using Anaconda, as of the time of writing this comment (31/03/2020):
以下是截至撰写此评论时 (31/03/2020) 在 Windows 上使用 Anaconda 从官方渠道安装 PyTorch 包的方法：
PyTorch without CUDA:
没有 CUDA 的 PyTorch：
conda install pytorch torchvision cpuonly -c pytorch
PyTorch with CUDA 10.1:
带有 CUDA 10.1 的 PyTorch：
conda install pytorch torchvision cudatoolkit=10.1 -c pytorch

go to the official website: http://pytorch.org/
去官网：http: //pytorch.org/
- Select Windows as your operating system
- Select your Package Manager such as pip or conda
- Select you python version
- Select CUDA or choose none You will get the command that will install pytorch on your system based on your selection.
- 选择 Windows 作为您的操作系统
- 选择您的包管理器，例如 pip 或 conda
- 选择你的python版本
- 选择 CUDA 或选择 none 您将获得将根据您的选择在您的系统上安装 pytorch 的命令。
For example, if you choose Windows, pip, python 3.6and nonein the listed steps, you will get the following commands:
例如，如果您在列出的步骤中选择Windows、pip、python 3.6和none，您将获得以下命令：
pip3 install http://download.pytorch.org/whl/cpu/torch-0.4.0-cp36-cp36m-win_amd64.whl
pip3 install torchvision

Actual answer:
实际答案：
Best way is to check on the official websitefor up-to-date options. Here are the ones working as of 2020-03:
最好的方法是在官方网站上查看最新选项。以下是截至 2020-03 年的工作：
# for windows 10, CUDA 10.1
conda install pytorch torchvision cudatoolkit=10.1 -c pytorch
#for windows 10, CUDA 9
conda install pytorch torchvision cudatoolkit=9.2 -c pytorch -c defaults -c numba/label/dev

It seems that the author (peterjc123) released 2 days ago conda packages to install PyTorch 0.3.0 on windows. Here is a copy:
似乎作者（peterjc123）在 2 天前发布了 conda 包来在 Windows 上安装 PyTorch 0.3.0。这是一个副本：
# for Windows 10 and Windows Server 2016, CUDA 8
conda install -c peterjc123 pytorch cuda80
# for Windows 10 and Windows Server 2016, CUDA 9
conda install -c peterjc123 pytorch cuda90
# for Windows 7/8/8.1 and Windows Server 2008/2012, CUDA 8
conda install -c peterjc123 pytorch_legacy cuda80

If you are trying to install on windows 10 and you are not having the anaconda installation than the best options are below:
如果您尝试在 Windows 10 上安装并且您没有安装 anaconda，那么最好的选择如下：
Python 2.7
蟒蛇 2.7
pip install https://download.pytorch.org/whl/cpu/torch-1.0.1-cp27-cp27mu-linux_x86_64.whl
pip install torchvision
If the above command does not work, then you have python 2.7 UCS2, use this command
如果上面的命令不起作用，那么你有python 2.7 UCS2，使用这个命令
pip install https://download.pytorch.org/whl/cpu/torch-1.0.1-cp27-cp27m-linux_x86_64.whl
Python 3.5
蟒蛇 3.5
pip3 install https://download.pytorch.org/whl/cpu/torch-1.0.1-cp35-cp35m-win_amd64.whl
pip3 install torchvision
Python 3.6
蟒蛇 3.6
pip3 install https://download.pytorch.org/whl/cpu/torch-1.0.1-cp36-cp36m-win_amd64.whl
pip3 install torchvision
Python 3.7
蟒蛇 3.7
pip3 install https://download.pytorch.org/whl/cpu/torch-1.0.1-cp37-cp37m-win_amd64.whl
pip3 install torchvision

Update June 2019: pytorch has a dedicated conda channel now and can be installed easily with anaconda. The command generated at pytorch will require dependencies before it can be executed successfully. For example I chose stable pytorch 1.1 build with python 3.6 and Cuda 10.0. The command generated by pytorch page was as follows:
2019 年 6 月更新：pytorch 现在有一个专用的 conda 频道，可以使用 anaconda 轻松安装。在 pytorch 生成的命令需要依赖才能成功执行。例如，我选择了带有 python 3.6 和 Cuda 10.0 的稳定 pytorch 1.1 版本。pytorch页面生成的命令如下：
conda install pytorch torchvision cudatoolkit=10.0 -c pytorch
conda 安装 pytorch torchvision cudatoolkit=10.0 -c pytorch
But it will not work if you have created a new conda environment like me. The step by step process for setting up pytorch is as follows:
但是如果你像我一样创建了一个新的 conda 环境，它就行不通了。设置pytorch的分步过程如下：
- First install the cudatoolkit as follows:
- 首先安装cudatoolkit，如下所示：
conda install -c anaconda cudatoolkit=10.0
conda install -c anaconda cudatoolkit=10.0
- Then install the mkl_fft as follows:
- 然后安装 mkl_fft 如下：
conda install -c anaconda mkl_fft
conda install -c anaconda mkl_fft
- Assuming you will face no more dependency issues. Use the following command to setup pytorch:
- 假设您将不再面临依赖问题。使用以下命令设置 pytorch：
conda install -c pytorch pytorch
conda install -c pytorch pytorch
This worked for me. But I had setup my new conda environment with scikit-learn and jupyter notebook before starting the pytorch setup. So if any dependency problem arise, it would be a good idea to install both scikit-learn and jupyter notebook as well.
这对我有用。但是在开始 pytorch 设置之前，我已经使用 scikit-learn 和 jupyter notebook 设置了我的新 conda 环境。因此，如果出现任何依赖问题，最好同时安装 scikit-learn 和 jupyter notebook。
