Package: waifu2x-ncnn-vulkan-python
waifu2x ncnn Vulkan PythonIntroductionA Python FFI of nihui/waifu2x-ncnn-vulkan achieved with SWIG.waifu2x-ncnn-vulkanis nihui's ncnn implementation of waifu2x converter. Runs fast on Intel / AMD / Nvidia with Vulkan API.This project only wrapped the original Waifu2x class. As a result, functions other than the core upscaling and denoising such as multi-thread loading and saving are not available. Of course, the auto tilesize and prepadding settings are implemented, so don't worry about them.Downloadlinux x64, Windows x64 and MacOS x64 releases are available now. For other platforms, you may compile it on your own.
The reason why MacOS ARM64 build is not available is that it needs ARM Python Dev Libs which I have no ideas on how to
get it on Github's MacOS x64 VM. Moreover, I don't have a Mac.However, for Linux (Like Ubuntu 18.04) with an older GLIBC (version < 2.29), you may try to use the ubuntu-1804 release or just compile it on your own.Windows release is not working for all python version. The version of Windows build is for python 3.9. This is a known issue:ImportError: DLL load failed while importing _rife_ncnn_vulkan_wrapper: The specified module could not be found.Updates:The binary wheel releases on Github are now linked with specific python version. Please download the right one according to your python version.it has been uploaded to PyPI, and you can install it with pip now. But you need to have all thebuild dependencies(SWIG and Vulkan Dev) installed. Because the PYPI package of this lib is a source distribution.Installationpipinstallwaifu2x-ncnn-vulkan-pythonBuildFirst, you have to install python, python development package (Python native development libs in Visual Studio), vulkan SDK and SWIG on your platform. And then, there are two ways to build it:Use setuptools to build and install into python package directly. (Currently in developing)Use CMake directly (The old way)Use setuptoolspythonsetup.pyinstallUse CMakeLinuxinstall dependencies: cmake, vulkan sdk, swig and python-devDebian, Ubuntu and other Debian-like Distrosapt-getinstallcmakelibvulkan-devswigpython3-devArch Distrospacman-Sbase-develcmakevulkan-headersvulkan-icd-loaderswigpythonBuild with CMakegitclone--recursivehttps://github.com/media2x/waifu2x-ncnn-vulkan-python.gitcdwaifu2x-ncnn-vulkan-python

cmake--buildbuildWindowsI used Visual Studio 2019 and msvc v142 to build this project for Windows.Install visual studio and open the project directory, and build. Job done.One way isusing Visual Studio to open the project as directory, and build it from Visual Studio.
And another way is build it from powershell just like what is written in therelease.ymlMac OS Xinstall dependencies: cmake, vulkan sdk, swig and python-devdownload vulkan sdk fromhttps://vulkan.lunarg.com/sdk/homeIf you have homebrew installed, run the command below to get SWIGbrewinstallswigI guess python dev is out-of-box in Mac. If not, google it.Build with CMakeYou can pass -DUSE_STATIC_MOLTENVK=ON option to avoid linking the vulkan loader library on MacOSThe remaining steps are similar to Linux.UsagesExample programfromPILimportImagefromwaifu2x_ncnn_vulkanimportWaifu2xwithImage.open("input.png")asimage:waifu2x=Waifu2x(gpuid=0,scale=2,noise=3)image=waifu2x.process(image)image.save("output.png")DocsKnown issuesModule finalization will crash for nvidia dedicated graphics card(s) on Linux.
