Description Paul Osmialowski 2018-06-30 19:01:26 UTC

Due to use of incompatible -mfpu=neon flag during compiler invocation, tensorflow can't be build for arm64.

Reproducible: Always

Steps to Reproduce:
1. emerge tensorflow
2.
3.
Actual Results:  
build failed

Expected Results:  
build succeeded

Note that even with proposed that one needs to build tensorflow with USE="-python" in order to succeed (but I guess this is not arm64-related problem)

tensorflow-1.9 is no longer in Gentoo, is this bug still there for 1.11?

Comment 3 Paul Osmialowski 2018-11-13 17:27:59 UTC

Indeed, I managed to upgrade to 1.11.0 with my patch removed.
