Cannot compile candle-transformers

Using the latest commit (#2584) I get the following when running

Which version of the rust toolchain are you using? It might not be recent enough so if it's not 1.81 or above I would suggest updating and seeing if it helps.

Hi @LaurentMazare, my sincerest apologies, I have upgraded rustc to 1.82 and candle-transformers compiles perfectly.

(base) ➜  candle git:(main) ✗ rustup -V
rustup 1.27.1 (54dd3d00f 2024-04-24)
info: This is the version for the rustup toolchain manager, not the rustc compiler.
info: The currently active `rustc` version is `rustc 1.82.0 (f6e511eec 2024-10-15)`

Thank you for your guidance!
