abseil error building tensorflow 1.15

[Brian Kramer]

Good morning, Abseil.io.

Interestingly, I never heard of Abseil until this morning when I got this error after upgrading from Tensorflow 1.11 to 1.15:

./tensorflow/stream_executor/stream_executor_pimpl.h:775:22: error: no template named 'make_unique' in namespace 'absl'; did you mean 'std::make_unique'?

  auto kernel_base = absl::make_unique<TypedKernel<Args...>>(this);

                     ^~~~~~~~~~~~~~~~~

                     std::make_unique

/home/bkramer/codulus/release/external/install/include/memory:3026:1: note: 'std::make_unique' declared here

make_unique(_Args&&... __args)

Can anyone point me in the right direction, while i go off and try to figure this out also on my own?

Thanks,
Brian Kramer

That file (stream_executor_pimpl.h) needs to #include "absl/memory/memory.h" in order to use absl::make_unique.  If you're building with Bazel, you'll probably also need to add a corresponding dependency on "@com_google_absl//absl/memory".

This appears to have been fixed in version (2.2.0) by https://github.com/tensorflow/tensorflow/commit/5a89c813f0973e1e8ad913d60dd4def822674fbf.

You can either upgrade TF further to at least that version, try to patch that commit onto the version you've got, or make the #include change manually.
