### Ollama Model File Location and Format When working with Ollama, it is essential to specify the model file's location correctly. The GGUF file must either use an absolute path or a path that is relative to the Modelfile’s location[^1]. This ensures proper identification of where the model resides on your system. For local execution without writing code, specific requirements apply depending upon whether you are using GGUF or Safetensors formats[^2]. Both these formats have their own advantages but require adherence to certain conventions when configuring models within environments like Ollama. An example of downloading such files includes obtaining `qwen2-0_5b-instruct-q4_0.gguf` from platforms such as Hugging Face (HF) or ModelScope[^3], which can then serve as input into applications utilizing services similar to those provided by Ollama. Additionally, functions exist for interfacing with Ollama via environment variables specifying its base URL along with desired model names; this setup facilitates creating instances capable of handling chat requests effectively[^4]. ```python import os from ollama import ChatOllama def get_chat_instance(): base_url = os.getenv('OLLAMA_BASE_URL', 'http://localhost:11434') model_name = os.getenv('MODEL_NAME', 'default_model') return ChatOllama(base_url=base_url, model=model_name) chat_instance = get_chat_instance() print(chat_instance) ```
