Hi,
I made a TensorFlow easyconfig a while ago depending on Python with the foss
toolchain; and including a variant with GPU support (PR 4904). The latter has
not yet been merged, probably because it is annoying to have something that can
only build on a machine with a GPU (it fails the sanity check otherwise, as
TensorFlow with GPU support cannot load on a machine without it).
Not being able to test this on a non-GPU system is a bit unfortunate,
but that's not a reason that it hasn't been merged yet, that's mostly
due to a lack of time from my side to get back to it...
Since I made that PR, two newer releases of TensorFlow have appeared (1.3 and
1.4). There are easyconfigs for 1.3 with the Intel tool chain. I am
considering making easyconfigs for TensorFlow 1.4 with Python-3.6.3-foss-2017b
(both with and without GPU support), but first I would like to know if anybody
else is doing this - it is my impression that somebody who actually know what
they are doing may be working on TensorFlow. :-)
I have spent quite a bit of time puzzling together an easyblock that
supports building TensorFlow from source, see [1].
It already works for non-GPU installations (see [2] for example), but
it's not entirely finished yet because:
* building from source with CUDA support does not work yet, the build
fails with strange Bazel errors...
* there are some issues when the TensorFlow easyblock is used together
with --use-ccache and the Intel compilers;
because two compiler wrappers are used, they end up calling each
other resulting in a "fork bomb" style situation...
I would really like to get it finished and have easyconfigs available
for TensorFlow 1.4 and newer where we properly build TensorFlow from
source rather than using the binary wheels...
Are you up for giving it a try, and maybe helping out with the problems
mentioned above?
regards,
Kenneth
