Only dependencies which aren't highly likely to be featured in a ARM development environment are featured here, Obvious dependencies such as Python3, Python2, pip, wheel, GCC etc. aren't covered here.


Note : Use bazel 1.x.x for Ray as 2.x.x is not supported.

Building Apache Arrow and pyarrow on ARMv8

Why build Apache Arrow from source on ARM?

Apache Arrow is an in-memory data structure used in several projects. It's python module can be used to save what's on the memory to the disk via python code, commonly used in the Machine Learning projects. With low RAM, ARM devices can make use of it but there seems to be an configuration error with the packaged binaries as of version 0.15.1 and so we're forced to build and install from the source.

The installation build steps are based on official guidelines but modified for ARM and has taken clues from building Ray for ARM.
