Overview

This tutorial aims to provide an overview of the configuration system of DecodingTrust. Our goal is to provide users with a simple entry (main.py) to execute selected (or all) trustworthiness perspectives

Configuration

The main.py script uses Hydra for managing configurations. Our codebase comes with a BaseConfig that specifies general information like model names and secret keys. To avoid combinatorially many configuration files, we use a modularized scheme as the configure management. Each trustworthy perspective, e.g. adversarial robustness as AdvGLUEConfig, extends BaseConfig and stores its dedicated configurations in its separate folder under ./configs. The configurations are defined in the configs.py script and registered with Hydra's ConfigStore in main.py.

You can provide input to the script through a YAML configuration file. This file should be located in the ./src/dt/configs directory. We have provided a default configuration set in ./configs.

Concretely, the top-level main configuration file (./configs/config.yaml) contains basic information required by all perspectives such as model configuration (model_config) and API key (key). We also support specifying model configuration as a config group located in ./configs/model_config.

We support three types of model name specifications.

• OpenAI Models: openai/model-name
• Huggingface Hub Models: hf/namespace/repo-name
• Local Models: hf//path/to/local/hf/repo

model: "hf/meta-llama/Llama-2-7b-chat-hf"
type: CHAT
conv_template: "llama-2"

model_loader: HF
torch_dtype: BFLOAT16
quant_file: null
tokenizer_name: null
trust_remote_code: true
use_auth_token: true

This is an example of the sub-configuration file for testing AdvGLUE++ data generated against an Alpaca base model, referenced in the top-level file as adv-glue-plus-plus: alpaca.

sys: false
demo: true
data_file: ./data/adv-glue-plus-plus/data/alpaca.json
out_file: ./results/adv-glue-plus-plus/${model_config.model}/alpaca-demo.json
no_adv: false
resume: false
save_interval: 100
remove_newline: false
task: ["sst2", "qqp", "mnli"]

Running the Script

To run our evaluations with the default settings for each perspective, simply run dt-run.

Running custom evaluations

Run AdvGLUE++ as an example of classification

To run our evaluations with your custom configuration, you can simply override the argument in command line input. For example, to test AdvGLUE++ on adversarial texts generated by Vicuna (./configs/vicuna.yaml) instead of Alpaca, simply run

dt-run --config-name config +model_config=hf +advglue=vicuna

Run RealToxicityPrompts as an example of generation

To evaluate toxicity on our sampled toxic prompts from RealToxicityPrompt, you can simply override the argument in command line input. For example,

dt-run --config-name config +model_config=hf +toxicity=realtoxicityprompts-toxic

We can also easily change the evaluation dataset from RealToxicityPrompt to gpt-4 generated VERY TOXIC prompts with the following command:

dt-run --config-name config +model_config=hf +toxicity=toxic-gpt4

Run with your custom config

Alternatively, you can also compose a different configuration file in ./configs and supply it to command line input.

  dt-run --config-name=another-config.yaml

Output Format

We provide a unified output format for different trustworthiness perspectives. Take AdvGLUE++ as an example. The output files will be written to ./results/adv-glue-plus-plus/model-organization/model-name in the following format to record the raw model queries, raw responses, parsed results, labels, and scores for each task:
