From a2ecd7a0e645a035dfaf4add2f587275908a2256 Mon Sep 17 00:00:00 2001 From: Net Zhang Date: Mon, 26 Jan 2026 14:13:49 -0500 Subject: [PATCH 01/37] feat: add shared module with reusable utils, services, and components Introduces a new `shared/` module structure to support application separation and code reuse across multiple Streamlit apps. ## Structure ### shared/utils/ - `clustering.py`: Dimensionality reduction (PCA, t-SNE, UMAP) and K-means clustering with multi-backend support (sklearn, FAISS, cuML) - `io.py`: File I/O utilities for embeddings and data persistence - `models.py`: Shared data models and type definitions ### shared/services/ - `clustering_service.py`: High-level clustering workflow orchestration - `embedding_service.py`: Image embedding generation using various models - `file_service.py`: File discovery and validation services ### shared/components/ - `clustering_controls.py`: Streamlit UI controls for backend selection, seed configuration, and worker settings - `summary.py`: Cluster summary statistics and representative images - `visualization.py`: Scatter plot visualization with Altair ### shared/lib/ - `progress.py`: Progress tracking utilities for long-running operations ## Backend Support - sklearn: Default CPU backend for all operations - FAISS: Optional GPU/CPU accelerated K-means clustering - cuML: Optional RAPIDS GPU acceleration for dim reduction and clustering with automatic fallback on unsupported architectures Co-Authored-By: Claude Opus 4.5 --- shared/__init__.py | 5 + shared/components/__init__.py | 14 ++ shared/components/clustering_controls.py | 108 +++++++++ shared/components/summary.py | 196 ++++++++++++++++ shared/components/visualization.py | 80 +++++++ shared/lib/__init__.py | 7 + shared/lib/progress.py | 61 +++++ shared/services/__init__.py | 9 + shared/services/clustering_service.py | 113 +++++++++ shared/services/embedding_service.py | 142 ++++++++++++ shared/services/file_service.py | 111 +++++++++ shared/utils/__init__.py | 9 + shared/utils/clustering.py | 284 +++++++++++++++++++++++ shared/utils/io.py | 45 ++++ shared/utils/models.py | 24 ++ 15 files changed, 1208 insertions(+) create mode 100644 shared/__init__.py create mode 100644 shared/components/__init__.py create mode 100644 shared/components/clustering_controls.py create mode 100644 shared/components/summary.py create mode 100644 shared/components/visualization.py create mode 100644 shared/lib/__init__.py create mode 100644 shared/lib/progress.py create mode 100644 shared/services/__init__.py create mode 100644 shared/services/clustering_service.py create mode 100644 shared/services/embedding_service.py create mode 100644 shared/services/file_service.py create mode 100644 shared/utils/__init__.py create mode 100644 shared/utils/clustering.py create mode 100644 shared/utils/io.py create mode 100644 shared/utils/models.py diff --git a/shared/__init__.py b/shared/__init__.py new file mode 100644 index 0000000..ae13b8e --- /dev/null +++ b/shared/__init__.py @@ -0,0 +1,5 @@ +""" +Shared utilities and services for the emb-explorer applications. +""" + +__version__ = "0.1.0" diff --git a/shared/components/__init__.py b/shared/components/__init__.py new file mode 100644 index 0000000..8857ec9 --- /dev/null +++ b/shared/components/__init__.py @@ -0,0 +1,14 @@ +""" +Shared UI components. +""" + +from shared.components.clustering_controls import render_clustering_backend_controls, render_basic_clustering_controls +from shared.components.visualization import render_scatter_plot +from shared.components.summary import render_clustering_summary + +__all__ = [ + "render_clustering_backend_controls", + "render_basic_clustering_controls", + "render_scatter_plot", + "render_clustering_summary" +] diff --git a/shared/components/clustering_controls.py b/shared/components/clustering_controls.py new file mode 100644 index 0000000..0aba28a --- /dev/null +++ b/shared/components/clustering_controls.py @@ -0,0 +1,108 @@ +""" +Shared clustering controls component. +""" + +import streamlit as st +from typing import Tuple, Optional + + +def render_clustering_backend_controls(): + """ + Render clustering backend selection controls. + + Returns: + Tuple of (dim_reduction_backend, clustering_backend, n_workers, seed) + """ + # Backend availability detection + dim_reduction_options = ["auto", "sklearn"] + clustering_options = ["auto", "sklearn"] + + has_faiss = False + has_cuml = False + has_cuda = False + + # Check for FAISS (clustering only) + try: + import faiss + has_faiss = True + clustering_options.append("faiss") + except ImportError: + pass + + # Check for cuML + CUDA (both dim reduction and clustering) + try: + import cuml + import cupy as cp + has_cuml = True + if cp.cuda.is_available(): + has_cuda = True + dim_reduction_options.append("cuml") + clustering_options.append("cuml") + except ImportError: + pass + + # Show backend status + use_seed = st.checkbox( + "Use fixed seed", + value=False, + help="Enable for reproducible results" + ) + + if use_seed: + seed = st.number_input( + "Random seed", + min_value=0, + max_value=999999, + value=614, + step=1, + help="Random seed for reproducible clustering results" + ) + else: + seed = None + + with st.expander("🔧 Available Backends:", expanded=False): + + # Explicit backend selection with two columns + col1, col2 = st.columns(2) + + with col1: + dim_reduction_backend = st.selectbox( + "Dimensionality Reduction Backend", + options=dim_reduction_options, + index=0, + help="Backend for PCA/t-SNE/UMAP computation" + ) + + with col2: + clustering_backend = st.selectbox( + "Clustering Backend", + options=clustering_options, + index=0, + help="Backend for K-means clustering computation" + ) + + # Performance and reproducibility settings + n_workers = st.number_input( + "N workers", + min_value=1, + max_value=64, + value=8, + step=1, + help="Number of parallel workers for CPU backends (sklearn, FAISS).

`app.py`: Legacy monolithic entry point (replaced by apps/) - `components/clustering/`: Entire directory moved to shared/ and apps/ - `pages/01_Clustering.py`: Now available as standalone embed_explore app ## Updated Imports - `components/precalculated/sidebar.py`: Uses shared.services and shared.components for clustering functionality - `pages/02_Precalculated_Embeddings.py`: Uses shared.components for visualization and summary rendering ## pyproject.toml Changes - Entry points updated: - `emb-embed-explore` → apps.embed_explore.app:main - `list-models` → shared.utils.models:list_available_models - Package includes: shared/, apps/ - Dependencies: - streamlit>=1.50.0 (updated for new API) -

Add shared/utils/backend.py with centralized backend utilities: - check_cuda_available(): Cached CUDA detection via PyTorch/CuPy - resolve_backend(): Auto-resolve to cuML/FAISS/sklearn based on hardware - is_oom_error(), is_cuda_arch_error(), is_gpu_error(): Error classification - Update embed_explore to use robust error handling: - Auto-resolve backends based on available hardware - Automatic fallback to sklearn on GPU errors - Consistent logging of backend selection - Update precalculated to use shared backend utilities: - Remove duplicate check_cuda_available/resolve_backend functions - Replace print() with logger calls for consistency Both apps now have identical backend selection and fallback behavior.

Only trigger st.rerun(scope="app") when the selected point actually changes. Run cuML UMAP in an isolated subprocess with L2-normalized embeddings to prevent SIGFPE crashes (NN-descent numerical instability with large-magnitude embeddings). Falls back to sklearn UMAP automatically if the subprocess fails.

From 92e639be337189254b3c89fb9944502724eb663b Mon Sep 17 00:00:00 2001 From: Net Zhang Date: Thu, 12 Feb 2026 12:44:45 -0500 Subject: [PATCH 27/37] test: add test suite (98 tests) and address PR review comments MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add comprehensive test suite covering shared utilities, clustering logic, backend detection, PyArrow filters, taxonomy tree, and logging config. All tests pass on both CPU (login nodes) and GPU (Pitzer V100). Also addresses valid Copilot PR review comments: remove unused variables and imports, simplify lambda in reduce(), add comments to silent except clauses, document numpy cap and faiss-gpu-cu12 in cu13 section. Fix real bug found by tests: build_taxonomic_tree() NaN handling — np.nan is truthy so `val or 'Unknown'` didn't work; replaced with pd.isna().

28/37] perf: lazy-load heavy libraries to fix slow app startup (#12) Move sklearn, umap, faiss, cuml, cupy, torch, and open_clip imports from module-level into the functions that use them. Use importlib.find_spec() for instant package detection in backend.py and clustering_controls.py dropdown population. Also remove eager re-exports from __init__.py files that were forcing all submodules to load at package import time (shared/utils/__init__.py was importing open_clip via models.py on every startup). App startup drops from ~5.7s to ~1.2s (4.7x faster). Heavy libraries now load on-demand when user clicks "Run Clustering" or "Generate Embeddings". 98 tests pass with no regressions.
