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]

没有解决，我还是面临这
1.git clone https://github.com/pytorch/vision.git
2 cd vision
3 mkdir build && cd build
4 cmake -DCMAKE_PREFIX_PATH=/path/to/libtorch -DCMAKE_INSTALL_PREFIX=/where/to/install/torchvision -DCMAKE_BUILD_TYPE=Release ..
5.make
在进行第5步的时候make时候出现错误

@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)

CMake Error at CMakeLists.txt:7 (find_package):
By not providing "FindTorchVision.cmake" in CMAKE_MODULE_PATH this project
has asked CMake to find a package configuration file provided by
"TorchVision", but CMake did not find one.

Could not find a package configuration file provided by "TorchVision" with
any of the following names:

TorchVisionConfig.cmake
torchvision-config.cmake

Add the installation prefix of "TorchVision" to CMAKE_PREFIX_PATH or set
"TorchVision_DIR" to a directory containing one of the above files. If
"TorchVision" provides a separate development package or SDK, be sure it
has been installed.

我报这种错误，是不是需要源码安装torchvision
