Updated `.gitignore` to include `eval_runs/`. - Introduced `make_image_grid` function for creating tiled grid images from a list of RGB images. - Enhanced `process_single_trajectory` to support different methods for passing frames to VLM: either as a stream or as a concatenated grid. - Modified `VLMService` to analyze multiple images together with a single prompt. - Updated command-line arguments to allow configuration of frame sampling and passing method. - Improved documentation and comments for clarity on new functionalities. --- examples/droid_h5/.gitignore | 3 +- examples/droid_h5/evaluate_vlm_configs.py | 244 +++++++++++++++++++++ examples/droid_h5/simple_vlm_processing.py | 164 ++++++++++---- robodm/agent/tools/implementations.py | 16 +- robodm/agent/vlm_service.py | 49 ++++- 5 files changed, 424 insertions(+), 52 deletions(-) create mode 100644 examples/droid_h5/evaluate_vlm_configs.py diff --git a/examples/droid_h5/.gitignore b/examples/droid_h5/.gitignore index 8bb3d97..df52e0a 100644 --- a/examples/droid_h5/.gitignore +++ b/examples/droid_h5/.gitignore @@ -1,2 +1,3 @@ results/ -output/ \ No newline at end of file +output/ +eval_runs/ diff --git a/examples/droid_h5/evaluate_vlm_configs.py b/examples/droid_h5/evaluate_vlm_configs.py new file mode 100644 index 0000000..da0479a --- /dev/null +++ b/examples/droid_h5/evaluate_vlm_configs.py @@ -0,0 +1,244 @@ +#!/usr/bin/env python3 +""" +Evaluate VLM configurations on DROID trajectories. + +Features: +- Download trajectories once, reuse across runs +- Vary number of evenly sampled frames (e.g., 4, 8, 16, 32) +- Vary passing method: 'stream' (per-frame) vs 'concat' (tiled grid) +- Vary camera video path keys (e.g., 'ext1_mp4_path', 'wrist_mp4_path') +- Save per-run outputs into distinct folders +- Produce a summary CSV of accuracy per configuration + +Usage examples: + python evaluate_vlm_configs.py \ + --paths-file results/all_droid_trajectory_paths.txt \ + --num-trajectories 50 \ + --eval-root ./eval_runs \ + --frame-counts 4 8 16 32 \ + --passing-methods stream concat \ + --video-path-keys ext1_mp4_path wrist_mp4_path + + # Or specify GCS trajectories directly + python evaluate_vlm_configs.py \ + --trajectories gs://.../success/... gs://.../failure/... \ + --eval-root ./eval_runs +""" + +import argparse +import csv +import json +import os +import random +import time +from pathlib import Path +from typing import Dict, List, Optional, Tuple + +import numpy as np + +# Local imports +from simple_vlm_processing import process_trajectories_parallel +from droid_pipeline import download_trajectories + + +def load_paths(paths_file: str) -> List[str]: + try: + with open(paths_file, 'r') as f: + return [line.strip() for line in f if line.strip()] + except Exception as e: + print(f"āŒ Failed to load paths from {paths_file}: {e}") + return [] + + +def sample_paths(paths: List[str], k: Optional[int], balance: Optional[float], seed: Optional[int]) -> List[str]: + if seed is not None: + random.seed(seed) + if k is None or k <= 0 or k >= len(paths): + return list(paths) + if balance is None: + return random.sample(paths, k) + success_paths = [p for p in paths if 'success' in p.lower()] + failure_paths = [p for p in paths if 'failure' in p.lower()] + k_success = int(round(k * balance)) + k_failure = k -

From e2539efe39cbe6e01c4185deb2231c1dcf13a279 Mon Sep 17 00:00:00 2001 From: Your Name Date: Fri, 29 Aug 2025 05:10:31 +0000 Subject: [PATCH 46/50] Refactor VLM processing to focus on MP4 input and remove unused parameters - Removed image_key and language_key parameters from VLM processing functions as they are not applicable for DROID directories with MP4 files. - Updated the pipeline to handle multiple trials for VLM evaluations, including saving per-trial metrics and aggregate results. - Simplified the example usage in `simple_vlm_processing.py` to reflect the new input format and removed state visualization functionality. - Enhanced documentation to clarify the new input requirements and processing methods. --- examples/droid_h5/droid_pipeline.py | 2 -
