Hi mentors,
Does anyone have idea about the following very last blocker for libtensorflow?
We are really ready to upload TF once the C API unit tests passed without fatal
error.
procedure to reproduce::
1. download libtensorflow-cc1.10 and libtensorflow-dev from
debomatic-amd64 and install. (with version >= ...-A1u35). -A1u38 is
preferred
but it just started to build at time of writing.
http://debomatic-amd64.debian.net/distribution#experimental/tensorflow/1.10.1+dfsg-A1u35/buildlog
http://debomatic-amd64.debian.net/distribution#experimental/tensorflow/1.10.1+dfsg-A1u38/buildlog
Or just build it from the git repo if you like. (demomatic-amd64's
CPU is E5-2699v3 and TF takes ~30 mins for dom-amd64 to build.)
2. clone the git repo and checkout to master (the very latest commit).
https://salsa.debian.org/science-team/tensorflow
3. install B-D from experimental and prepare the environment
# apt build-dep .
$ ./debian/devh pre
4. run the unit test for C API
$ sh debian/tests/tf_c_api_test.sh
And you will see the attached failure log.
I asked for help here https://github.com/tensorflow/tensorflow/issues/22116
but still not reply.
