Raspberry Pi 3 docker missing information ?

[MyraBaba]

Hi,

According to the documentation :

Build

Please use a Native build with gcc 4 as explained below, higher compiler versions currently cause test failures on ARM

The following command will build a container with dependencies and tools and then compile MXNet for ARMv7. The resulting artifact will be located in build/mxnet-x.x.x-py2.py3-none-any.whl, copy this file to your Raspberry Pi.

ci/build.py -p armv7

I can't find the ci/build.py . command ?

is it a docker image I tried : docker run ci/build.py -p armv7 no such image ?

1 - What is the exact steps for compiling mxnet in docker which is host machine is mac os x. ?

2 - I compiled on the Raspberry pi 3 but when I try to load models it gives Segmentation fault ?

What is the working branch for Raspberry pi 3?

thanks

Hey, this is the MXNet Label Bot.
Thank you for submitting the issue! I will try and suggest some labels so that the appropriate MXNet community members can help resolve it.
Here are my recommended labels: Build

You should be able to run the build script using python3 ci/build.py -p armv7 from your incubator-mxnet directory. The master branch should work fine.

@mxnet-label-bot add [Build, Edge Devices]
