# Use ## Intended use The model follows instructions provided in the input. You should always preface your input with "Question: " and finish it with "Answer:", for example: "Question: Please write a function in Python that performs bubble sort. Answer:" **Feel free to share your generations in the Community tab!** ## Generation ```python # pip install -q transformers # pip install -e git+https://github.com/bigcode-project/astraios#subdirectory=peft from peft import PeftModel from transformers import AutoModelForCausalLM, AutoTokenizer peft_checkpoint = "bigcode/astraios-7b-adapterp" checkpoint = "bigcode/starcoderbase-7b" model = AutoModelForCausalLM.from_pretrained(checkpoint) model = PeftModel.from_pretrained(model, peft_checkpoint) device = "cuda" # for GPU usage or "cpu" for CPU usage tokenizer = AutoTokenizer.from_pretrained(checkpoint) model = AutoModelForCausalLM.from_pretrained(checkpoint).to(device) inputs = tokenizer.encode("Question: Please write a function in Python that performs bubble sort. Answer:", return_tensors="pt").to(device) outputs = model.generate(inputs) print(tokenizer.decode(outputs[0])) ``` # Training ## Model - **Architecture:** GPT-2 model with multi-query attention and Fill-in-the-Middle objective - **Steps:** 250k pretraining & 200 instruction tuning - **Precision:** fp32 ## Hardware - **Pretraining:** - **GPUs:** 512 Tesla A100 - **Training time:** 24 days - **Instruction tuning:** - **GPUs:** 8 Tesla A100 ## Software - **Orchestration:** [Megatron-LM/Transformers](https://github.com/bigcode-project/octopack#training) - **Neural networks:** [PyTorch](https://github.com/pytorch/pytorch) # Citation ```bibtex ```
