Bert-Burn Model

This project provides an example implementation for inference on the BERT family of models. The following compatible bert-variants: roberta-base(default)/roberta-large, bert-base-uncased/bert-large-uncased/bert-base-cased/bert-large-cased can be loaded as following. The pre-trained weights and config files are automatically downloaded from: HuggingFace Model hub

To include the model in your project

Add this to your Cargo.toml:

[dependencies]
bert-burn = { git = "https://github.com/tracel-ai/models", package = "bert-burn", default-features = false }

Example Usage

Example usage for getting sentence embedding from given input text. The model supports multiple backends from burn (e.g. ndarray, wgpu, tch-gpu, tch-cpu, cuda) which can be selected using the --features flag. An example with wgpu backend is shown below. The fusion flag is used to enable kernel fusion for the wgpu backend. It is not required with other backends. The safetensors flag is used to support loading weights in safetensors format via candle-core crate.

WGPU backend

cd bert-burn/
# Get sentence embeddings from the RobBERTa encoder (default)
cargo run --example infer-embedding --release --features wgpu,fusion,safetensors

# Using bert-base-uncased model
cargo run --example infer-embedding --release --features wgpu,fusion,safetensors bert-base-uncased 

# Using roberta-large model
cargo run --example infer-embedding --release --features wgpu,fusion,safetensors roberta-large
