Description illule 2020-05-06 23:23:25 UTC

Can't install tensorflow 2.1.0 with 1.9.3_pre20200412. bazel complains about missing autolink.h

An ugly workaround:

echo '#include "config.h"' > /usr/include/jsoncpp/json/autolink.h

patch resolving tensorlfow 2.1 installation issue

In order to successfully install tensorflow I had to had these to package.mask
   2   │ >=net-libs/grpc-1.28.1
   3   │ >=dev-python/grpc-1.28.0
   4   │ >=dev-python/grpcio-tools-1.28.1
And appply the attach patch

I had this problem also.

Looks like jsoncpp is the culprit, here. My system wants >=jsoncpp-1.9.2, but the only versions in Portage are 1.9.1, and 1.9.3_pre20200412 (which seems broken)

I resolved the issue by grabbing a copy of jsoncpp-1.9.2-r2.ebuild and dropping it into my local overlay. With that version installed, Tensorflow builds without issue.

I found the ebuild for 1.9.2 here: https://gitlab.com/liguros/core-kit/-/blob/3938cb4eb8810a50be217710079f0446df702307/dev-libs/jsoncpp/jsoncpp-1.9.2-r2.ebuild but that was just the first hit on Google.

This issue appears to persist in tensorflow 2.2.0_rc2. Reverting to:

net-libs/grpc-1.26.0-r1
dev-python/grpcio-tools-1.26.0
dev-libs/jsoncpp-1.9.2-r2 (custom ebuild as mentioned by Simon Detheridge)

seems to have fixed the problem.

Furthermore, when compiling with CUDA (dev-util/nvidia-cuda-toolkit), GCC <= 8.3 is required, which no longer seems to be a system default (17.1 profile). This creates its own set of problems; switching between GCC's makes reasoning about linking errors difficult.

I did not find the patch to be necessary in 2.2.0.

Could be related to bug 719274

This is fixed in TF-2.2 and 2.3 :)
