New Features
Enhancements and Bug Fixes
Annoncements ChainerCV changed CI to test both on Chainer v2 and Chainer v3 (alpha). Since there are users that use development version and stable version of Chainer, ChainerCV will try to support both versions of Chainer as much as possible. The priority is on stable version of Chainer, and ChainerCV will be made sure to always work on the stable version. The development version will be supported while it is possible to support the two versions simultaneously. This means that CI tests will run with the development version and the stable version. In ChainerCV, new features added to Chainer will not be used. If a new feature is necessary, the relevant part can be copied to ChainerCV temporarily. In this case, the code will be deleted once the development version is released.
