You can use it by running the command ```ollama run stuehieyr/medleymd``` in your terminal. If you have limited computing resources, check out this [video](https://www.youtube.com/watch?v=Qa1h7ygwQq8) to learn how to run it on a Google Colab backend. ## 💻 Usage ```python !pip install -qU transformers bitsandbytes accelerate from transformers import AutoTokenizer import transformers import torch model = "sethuiyer/MedleyMD" tokenizer = AutoTokenizer.from_pretrained(model) pipeline = transformers.pipeline( "text-generation", model=model, model_kwargs={"torch_dtype": torch.bfloat16, "load_in_4bit": True}, ) generation_kwargs = { "max_new_tokens": 512, "do_sample": True, "temperature": 0.7, "top_k": 50, "top_p": 95, } messages = [{"role":"system", "content":"You are an helpful AI assistant. Please use when you want to end the answer."}, {"role": "user", "content": "Explain what a Mixture of Experts is in less than 100 words."}] prompt = pipeline.tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True) outputs = pipeline(prompt, **generation_kwargs) print(outputs[0]["generated_text"]) ``` ```text A Mixture of Experts (Mixout) is a neural network architecture that combines the strengths of multiple expert networks to make a more accurate and robust prediction. It is composed of a topmost gating network that assigns weights to each expert network based on their performance on past input samples. The expert networks are trained independently, and the gating network learns to choose the best combination of these experts to make the final prediction. Mixout demonstrates a stronger ability to handle complex data distributions and is more efficient in terms of training time and memory usage compared to a traditional ensemble approach. ```
