[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
