Version 0.13 build failure

Hi, @ankane.

Can't figure out the origin of the following problem. I can't build the gem, neither on my servers (against libtorch 2.0.0) nor in the pipeline in my GitHub fork.

../../../../ext/torch/backends.cpp: In function ‘void init_backends(Rice::Module&)’:

What I am missing here?

You need #40. ❤️

Many thanks, @Eric-Guo!

[ankane]

Thanks for reporting. 0.13.1 is out with @Eric-Guo's fix.
