A week ago, on October 10, 2020, tensorflow-2.3.1 gracefully failed to compile with the following ERROR: sci-libs/tensorflow-2.3.1::gentoo failed (compile phase) and a few weeks before tensorflow-2.2.0-r2 caused a dependency conflict during a regular system update, so I updated my system excluding tensorflow and on October 10 tried, after another update excluding tensorflow, tried to update it to the last available version. Before doing it, I also unmasked some of its most recent dependencies (I think it was protobuf-3.13.0) to avoid dependency conflict.
Any thoughts on how to proceed with this obstacle other than to depclean tensorflow and try to reinstall it again? The problem is that all versions of tensorflow and almost all of its dependencies are masked by default. So it is almost impossible to guess which versions of them should be unmasked for the successful compilation. Is there any hope that in the future at least some version of tensorflow will be considered "stable" in Gentoo?
