# torchvision
|
|
|
|
[](https://pepy.tech/project/torchvision)
|
|
[](https://pytorch.org/vision/stable/index.html)
|
|
|
|
The torchvision package consists of popular datasets, model architectures, and common image transformations for computer
|
|
vision.
|
|
|
|
## Installation
|
|
|
|
Please refer to the [official
|
|
instructions](https://pytorch.org/get-started/locally/) to install the stable
|
|
versions of `torch` and `torchvision` on your system.
|
|
|
|
To build source, refer to our [contributing
|
|
page](https://github.com/pytorch/vision/blob/main/CONTRIBUTING.md#development-installation).
|
|
|
|
The following is the corresponding `torchvision` versions and supported Python
|
|
versions.

## Image Backends
|
|
|
|
Torchvision currently supports the following image backends:
|
|
|
|
- torch tensors
|
|
- PIL images:
|
|
- [Pillow](https://python-pillow.org/)
|
|
- [Pillow-SIMD](https://github.com/uploadcare/pillow-simd) - a **much faster** drop-in replacement for Pillow with SIMD.
|
|
|
|
Read more in in our [docs](https://pytorch.org/vision/stable/transforms.html).
|
|
|
|
## [UNSTABLE] Video Backend
|
|
|
|
Torchvision currently supports the following video backends:
|
|
|
|
- [pyav](https://github.com/PyAV-Org/PyAV) (default) - Pythonic binding for ffmpeg libraries.
|
|
- video_reader - This needs ffmpeg to be installed and torchvision to be built from source. There shouldn't be any
|
|
conflicting version of ffmpeg installed. Currently, this is only supported on Linux.
|
|
|
|
```
|
|
conda install -c conda-forge ffmpeg
|
|
python setup.py install
|
|
```
|
|
|
|
# Using the models on C++
|
|
|
|
TorchVision provides an example project for how to use the models on C++ using JIT Script.
|
|
|
|
Installation From source:
|
|
|
|
```
|
|
mkdir build
|
|
cd build
|
|
# Add -DWITH_CUDA=on support for the CUDA if needed
|
|
cmake ..
|
|
make
|
|
make install
|
|
```
|
|
|
|
Once installed, the library can be accessed in cmake (after properly configuring `CMAKE_PREFIX_PATH`) via the
|
|
`TorchVision::TorchVision` target:
|
|
|
|
```
|
|
find_package(TorchVision REQUIRED)
|
|
target_link_libraries(my-target PUBLIC TorchVision::TorchVision)
|
|
```
|
|
|
|
The `TorchVision` package will also automatically look for the `Torch` package and add it as a dependency to
|
|
`my-target`, so make sure that it is also available to cmake via the `CMAKE_PREFIX_PATH`.
|
|
|
|
For an example setup, take a look at `examples/cpp/hello_world`.
|
|
|
|
Python linking is disabled by default when compiling TorchVision with CMake, this allows you to run models without any
|
|
Python dependency. In some special cases where TorchVision's operators are used from Python code, you may need to link
|
|
to Python. This can be done by passing `-DUSE_PYTHON=on` to CMake.
|
|
|
|
### TorchVision Operators
|
|
|
|
In order to get the torchvision operators registered with torch (eg. for the JIT), all you need to do is to ensure that
|
|
you `#include <torchvision/vision.h>` in your project.
|
|
