I recently implemented pastiche, a PyTorch-based Python program for applying neural style transfer . Given a content image C and a style image S, neural style transfer (NST) synthesizes a new image I that retains the content from C and style from S. This is achieved by iteratively updating I so that relevant properties of its representation within the VGG neural network  approach the corresponding properties for C and S.
The library is available on PyPI and can be installed with pip.
$ pip3 install pastiche
The example image above was synthesized by applying the style from Vincent van Gogh’s The Starry Night to a photo I took in Boston in 2015.
