Do we still need FileNotFoundError then?

[bertmaher]

Yeah, so actually it's a little more complex than in my summary, if nvcc simply isn't there we'll get a FileNotFoundError, but in my case I have nvcc symlinked to ccache (as recommended in our dev setup guide) but no nvcc in my path. I think it's still valid to catch both here :)

Merge started

Your change will be merged immediately since you used the force (-f) flag, bypassing any CI checks (ETA: 1-5 minutes). Please use -f as last resort and instead consider -i/--ignore-current to continue the merge ignoring current failures. This will allow currently pending tests to finish and report signal before the merge.
