As described on its website, "TensorFlow is an open + source software library for numerical computation using data + flow graphs. Nodes in the graph represent mathematical + operations, while the graph edges represent the + multidimensional data arrays (tensors) communicated between + them. The flexible architecture allows you to deploy + computation to one or more CPUs or GPUs in a desktop, server, + or mobile device with a single API. TensorFlow was originally + developed by researchers and engineers working on the Google + Brain Team within Google's Machine Intelligence research + organization for the purposes of conducting machine learning + and deep neural networks research, but the system is general + enough to be applicable in a wide variety of other domains as + well."

+ +

TensorFlow now is the most popular platform/library for machine + learning and AI. There are official binaries for Linux, Mac, + Windows, and Android, but no official support for &os;. For + the last several months, I have done some work to make + TensorFlow available on &os;. Some notable work:

+ +

Patch bazel to not depend on /proc at + build time. bazel is a build tool made by Google. + It uses /proc to get path-to-self when building C++ + code, but mounting /proc is usually not allowed + when building as an unprivileged user.
TensorFlow can now be built on &os; 10.x by using + clang38 as the default bazel cross-build + tool.
Patch the bazel workspace files to allow + TensorFlow to be built using offline third-party + dependencies. This work is needed because the &os; Ports + framework does not allow network access except during the + fetch stage.
Fix the build on &os; i386.
Make TensorFlow build with either Python 2 or Python 3.
Update to the latest version, which is + tensorflow-1.2.0.

+ +

This port would not be possible without substantial + assistance from bapt@, lwhsu@, mat@, and koobs@ — thank + you for your help! You are very nice and I learned a lot + about &os; and the Ports framework from your help.

+ + + + Review, test, comment, and most importantly, commit to the + Ports Collection. + + Fix the OpenCL support on &os;. + + Port tensorflow-serving, which is a flexible, + high-performance serving system for machine learning models + produced by TensorFlow. + + Set up a CI for TensorFlow on &os; and give early notice + to upstream when they break TensorFlow on &os;. + +
