[lytning98]

system environment

cargo 1.85.0 (d73d2caf9 2024-12-31)

build command

cargo install --path router -F candle-cuda -F http --no-default-features

build errors

error[E0277]: the trait bound `half::bf16: SampleUniform` is not satisfied

Same with this candle issue: huggingface/candle#2805

After adding the --locked flag to cargo install, the compilation succeeded. If this isn't something that needs to be fixed, feel free to close this issue.

I encountered the same error on M1:

cargo install --path router -F metal

As suggested by @lytning98, add --locked to fix the problem:

cargo install --path router -F metal --locked

Yes, some subdependencies broke semver which makes cargo install fail.

Cargo install will always attempt to use latest patches if they exist which would break because of the semver breaking here.

cargo install --locked on the other hand will use exactly what Cargo.lock says it should running, running therefore the old dependency version that actually works.

I think we fixed everything on main now. It took a while since we upgrading many dependencies recently.
