Pre-Train BERT with Hugging Face Transformers and Habana Gaudi

Hugging Face 4 years ago 50

Hugging Face released a tutorial for pre-training BERT-base from scratch using Habana Gaudi accelerators on AWS, leveraging the Transformers and Optimum Habana libraries with masked-language modeling. The training ran for 100,000 steps with a global batch size of 256 over approximately 12.5 hours on a DL1 instance with 8 HPU-cores. Users can now train custom BERT models on Gaudi hardware by following the guide's four steps: dataset preparation, tokenizer training, dataset preprocessing, and distributed model pre-training.

Stable Diffusion with 🧨 Diffusers

Hugging Face 4 years ago 42

Stability AI and collaborators created Stable Diffusion, a text-to-image model trained on 512x512 images from the LAION-5B dataset, which can be run through the Diffusers library with just a few lines of code. The model uses latent diffusion with a default of 50 inference steps and achieves an 8x8 spatial compression ratio, reducing memory requirements so that 512×512 images can be generated on 16GB GPUs. Users can customize outputs by adjusting parameters like guidance_scale (7 to 8.5 recommended), num_inference_steps, and image dimensions, with quality improving as step count increases but generation time slowing proportionally.
