Hey @MadBomber, thanks for reporting. What version of LibTorch are you using?

MadBomber commented 3 years ago

You are right. Sorry I should have caught that. brew told me that I had version 1.7.1_1 installed. I did a brew upgrade libtorch which installed version 1.8.1 which allowed the gem ins torch-rb to complete successfully.

FYI alias brewski='brew update && brew upgrade && brew cleanup; brew doctor'

Running brewski on a weekly basis should be a habit.
