# candle-onnx This crate adds ONNX support to candle ## FAQ #### Missing protoc installation when compiling candle-onnx The candle-onnx dependency prost-build no longer comes bundled with prost binaries. This could cause the following error when attempting to compile candle-onnx: ``` error: failed to run custom build command for `candle-onnx` Caused by: // (...) Could not find `protoc` installation and this build crate cannot proceed without this knowledge. ``` To fix this issue install protoc on your system and make it available in your system `PATH`. See the [protoc documentation](https://grpc.io/docs/protoc-installation/) for more information.
