Hey @ts19970816 could you add a little context about you environment? For example you can download and run our environment collection script and post the output here.

[ts19970816]

pytorch1.5.0 torchvision0.6.0 python3.6.5 cuda10.2 cudnn7.6.5 g++ 7.5

[pmeier]

1. What platform (Linux, macOS) and which version are you operating on?
2. Your error message suggests that you are building from the master branch while in your last comment you said torchvision==0.6.0. Which one is correct?

[ts19970816]

linux master 在哪里下载torchvision=0.6.0

[pmeier]

Sorry, but I don't speak Chinese, so I'm relying on Google Translator here. Do you have a reason to install from source or could you simply install the pre-compiled binaries? If source is not required you could run

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

[ts19970816]

thanks,pip install torch-1.5.0-cp36-cp36m-linux_x86_64.whl pip install torchvision-0.6.0-cp36-cp36m-linux_x86_64.whl 这是我的安装方式

[pmeier]

Does this mean, that your problem is resolved or are still facing difficulties of any kind?

@ts19970816 You need to clarify what you want to do:

• If you want to install torchvision==0.6.0 the pip command from my previous comment is enough.
• If you want to install torchvision from source you will not get 0.6.0, but rather the current development version (>= 0.8)

[ts19970816]

但是我在源码编译安装之前，已经通过pip install torchvision-0.6.0-cp36-cp36m-linux_x86_64.whl这种方式安装过了torchvision

[fmassa]

Hi,

It's very difficult for someone like @pmeier or myself who doesn't speak chinese to understand what you want to achieve.

Do you want to use the C++ API, or just the Python bindings? If it's just the Python bindings, you can install via setup.py.

If you want to use the C++ API, what exactly do you want to do, use an operator in C++, run one of the example models, or something else?

One of the errors you got seemed to be indicating that either you were not using a compatible PyTorch version, or you were not compiling with C++14.

[zhangguanheng66]

但是我在源码编译安装之前，已经通过pip install torchvision-0.6.0-cp36-cp36m-linux_x86_64.whl这种方式安装过了torchvision

@ts19970816 Could you ask questions in English? For this question, I can translate: Before installed from source code, I have installed torchvision with pip.

Last error seems to be due to an old cmake version that doesn't have the Python3 module

[fmassa]

@andfoy is working on adding CMake tests to CI in https://github.com/pytorch/vision/pull/2577, which will hopefully make it easier to catch bugs and will give some hints to user on how to use our CMake.
