Dear MXNet community, This is the 3-day vote to add conan support for Apache MXNet (incubating) version v1.4.1. The voting on dev@ list will start May 03 23:59:59 (PST) and close on May 06 23:59:59.
Background: conan is open-source, freeware, cross-platform package manager for C and C++ projects, written in python. it provides integration with various build systems, include CMake. conan may use bintray as a server to store and download pre-built packages, or packages might be always built from sources. Problem: currently (as for v1.4.1), Apache MXNet (incubating) is using several ways to fetch 3rd-party dependencies simultaneously, for instance: 1. download GitHub archives during the build - OpenBLAS - OpenCV 2. conda (alternative way to GitHub archives) 3. download from CMake - Intel Math Kernel Library (MKL) 4. Git submodules - cub - dlpack - dmlc-core - googletest - mkldnn - mshadow - onnx-tensorrt - openmp - ps-lite - tvm therefore, there are multiple places to look for 3rd parties, and its hard to update them, as you need to remember or figure it out how to update a particular dependency to newer version, for instance. current Apache MXNet (incubating) build instructions differ very much per platform, require to download and unzip some archives manually, specifying variables with paths to this archives, in conjunction of updating git submodules, Action: merge pull request providing an initial conan support for Apache MXNet (incubating). support conan as an alternate approach to fetch various 3rd-party dependencies. old approaches will be still available, supported and left intact.
