ComfyUI Node: Griptape Agent Config: Ollama

Griptape Agent Config: Ollama:

The Griptape Agent Config: Ollama node is designed to facilitate the use of local models with Ollama, a prompt driver available at https://ollama.com. This node allows you to configure and manage the settings required to run Ollama models effectively within the Griptape framework. By leveraging this node, you can specify various parameters such as the prompt model, base URL, port, and other options to tailor the behavior of the Ollama prompt driver to your specific needs. This configuration is essential for ensuring that the models operate correctly and efficiently, providing a seamless experience for tasks that require local model execution.

Griptape Agent Config: Ollama Input Parameters:

prompt_model

This parameter specifies the model to be used by the Ollama prompt driver. It allows you to select from available models, ensuring that the chosen model aligns with your task requirements. The default value is an empty string, indicating that no specific model is selected by default.

base_url

The base URL parameter defines the URL where the Ollama service is hosted. This is crucial for directing the prompt driver to the correct server location. The default value is set to the predefined ollama_base_url, ensuring that the service is correctly located unless otherwise specified.

port

This parameter specifies the port number on which the Ollama service is running. It is essential for establishing a connection to the correct service endpoint. The default value is set to the predefined ollama_port, ensuring proper connectivity unless a different port is required.

temperature

The temperature parameter controls the randomness of the model's output. A lower temperature will make the output more deterministic, while a higher temperature will increase variability. This parameter allows you to fine-tune the model's behavior to suit your specific needs.

seed

The seed parameter is used to initialize the random number generator, ensuring reproducibility of results. By setting a specific seed value, you can guarantee that the model produces the same output for the same input across different runs.

image_generation_driver

This optional parameter allows you to specify a custom image generation driver. By default, it uses DummyImageGenerationDriver(), but you can replace it with a driver that suits your image generation needs.

Griptape Agent Config: Ollama Output Parameters:

custom_config

The custom_config output parameter returns the configuration object created based on the provided input parameters. This object includes the prompt driver settings and any specified image generation driver, encapsulating all the necessary configurations for running the Ollama model effectively.

Griptape Agent Config: Ollama Usage Tips:

• Ensure that the base_url and port parameters are correctly set to match the server hosting the Ollama service to avoid connectivity issues.
• Adjust the temperature parameter based on the desired output variability; lower values for more predictable results and higher values for more creative outputs.
• Use the seed parameter to ensure reproducibility of results, especially when running experiments or generating consistent outputs.

Griptape Agent Config: Ollama Common Errors and Solutions:

"ConnectionError: Failed to connect to Ollama service"

• Explanation: This error occurs when the base URL or port is incorrect, preventing the prompt driver from connecting to the Ollama service.
• Solution: Verify that the base_url and port parameters are correctly set to the server hosting the Ollama service.

"ValueError: Invalid model specified"

• Explanation: This error indicates that the specified model in the prompt_model parameter is not recognized or available.
• Solution: Ensure that the prompt_model parameter is set to a valid model name supported by the Ollama service.

"TypeError: Temperature must be a float"

• Explanation: This error occurs when the temperature parameter is not provided as a float value.
• Solution: Check that the temperature parameter is correctly set to a float value, such as 0.7 or 1.0.

"RuntimeError: Seed value must be an integer"

• Explanation: This error indicates that the seed parameter is not provided as an integer.
• Solution: Ensure that the seed parameter is set to an integer value to initialize the random number generator correctly.
