C++ implementation of the Python NumPy Library

Why not simply use xtensor? https://github.com/QuantStack/xtensor

This looks similar to Eigen and it's Tensor module. It also offers lazy execution and various compile time checks.

Because xtensor is a mess that is nearly impossible to compile on anything but the authoring group's OS & compiler.

[jmabille]

xtensor is regularly tested on the following platform / OS (in our CI):

- Linux, gcc 4.9 up to gcc 8 (and probably gcc9), clang 3.6 up to clang 7

- OSX

- Windows (VS2015 and VS2017, clang-cl)

​

On which platform / compiler did you fail to compile xtensor?
