Python linking is disabled by default when compiling TorchVision with CMake, this allows you to run models without any Pythonĭependency.

So make sure that it is also available to cmake via the CMAKE_PREFIX_PATH.įor an example setup, take a look at examples/cpp/hello_world. The TorchVision package will also automatically look for the Torch package and add it as a dependency to my-target, Target_link_libraries(my-target PUBLIC TorchVision::TorchVision) Currently, this is only supported on Linux. There shouldn't be any conflicting version of ffmpeg installed. video_reader - This needs ffmpeg to be installed and torchvision to be built from source.pyav (default) - Pythonic binding for ffmpeg libraries.Torchvision currently supports the following video backends: Otherwise, add the include and library paths in the environment variables TORCHVISION_INCLUDE and TORCHVISION_LIBRARY, respectively. Make sure that it is available on the standard library locations, Notes: libpng and libjpeg must be available at compilation time in order to be available. libjpeg - can be installed via conda conda install jpeg or any of the package managers for debian-based and RHEL-based Linux distributions.libpng - can be installed via conda conda install libpng or any of the package managers for debian-based and RHEL-based Linux distributions.

accimage - if installed can be activated by calling t_image_backend('accimage').

If installed will be used as the default.

Pillow-SIMD - a much faster drop-in replacement for Pillow with SIMD.

Torchvision currently supports the following image backends: Which is useful when building a docker image. It's possible to force building GPU support by setting FORCE_CUDA=1 environment variable, The linked guide on the contributing page and retry the install.īy default, GPU support is built if CUDA is found and _available() is true. In case building TorchVision from source fails, install the nightly version of PyTorch following # or, for OSX # MACOSX_DEPLOYMENT_TARGET=10.9 CC=clang CXX=clang++ python setup.py install

Conda install ffmpeg python 3.5
