Compilation failures caused by xtensor-stack/xtensor#2923 #258
Description
Recently I have been getting the following compilation errors when trying to use xtensor-blas in my project.

The likely source of the problem is xtensor-stack/xtensor#2923.

This change is not part of a release, so we haven't updated xtensor-blas yet. It should build with xtensor 0.27.1.
[CI] Install the latest tagged versions of xtl, xtensor and xtensor-blas

@JohanMabille Thank you for the clarification, I have updated my workflows to install the latest tagged versions of xtensor components instead of using

Closing it since it should be solved, do not hesitate to reopen it if you have any issue with latest xtensor tag.
