torch-geometric

k-dense-ai/scie…t-skills

Supports PyTorch Geometric (PyG) graph neural networks — node/link/graph classification, message passing (GCN, GAT, GraphSAGE, GIN), heterogeneous graphs, neighbor sampling, and custom datasets. Use when working with torch_geometric, not for general NetworkX analytics or non-graph PyTorch models.

PyTorch Geometric (PyG)

PyG is the standard library for Graph Neural Networks built on PyTorch. It provides data structures for graphs, 60+ GNN layer implementations, scalable mini-batch training, and support for heterogeneous graphs.

Installation

Reviewed released torch-geometric 2.8.0.post1 (2026-10-01); CPU examples tested with Python 3.13 / PyTorch 2.14.1. Rolling latest docs identify 2.9.0; check the installed release before adopting new APIs. PyG 2.8 requires PyTorch 2.9+; its original release table covers 2.9–2.12. Our 2.14.1 core tests do not establish every extension/backend combination.

# Install the PyTorch build for your platform from https://pytorch.org/get-started/locally/
uv pip install torch==2.14.1
uv pip install torch-geometric==2.8.0.post1
python -c "import torch, torch_geometric; print(torch.__version__, torch.version.cuda, torch_geometric.__version__)"

Basic tensor-based layers need no extensions. Neighbor sampling requires pyg-lib or torch-sparse; spatial k-NN operators require pyg-lib in 2.8. torch-cluster and torch-spline-conv are deprecated and ignored. Inspect the wheel index for your exact Python/OS/Torch/CUDA tuple. Never install wheels for a different Torch release merely because core imports succeed. The tested macOS ARM CPU extension is below; choose a different matching wheel for other platforms, and verify its operators:

Applies to experimental design validity, biases and confounders, statistical interpretation, evidence grading frameworks (GRADE, Cochrane Risk of Bias), and teaching critical analysis. Supports evidence appraisal and identifying flaws; formal peer review writing belongs to peer-review.测试与安全2404literature-reviewk-dense-ai/scie…t-skillsConducts systematic, scoping, and narrative literature reviews using PubMed, arXiv, bioRxiv, Semantic Scholar, and other appropriate sources. Use for research synthesis, reproducible literature searches, screening, citation checking, or preparing Markdown and PDF reviews. Tracks search coverage, records versus studies, and evidence limitations; supports meta-analysis planning but does not supply a meta-analysis engine.测试与安全2382scientific-brainstormingk-dense-ai/scie…t-skillsFacilitates evidence-aware scientific ideation with independent generation, structured discussion, explicit assumptions, transparent evaluation, adversarial review, and decision logs. Use for early-stage research brainstorming or prioritizing candidate directions; hand off empirical validation, study design, ethics or regulatory review, and clinical questions to appropriate experts or skills.智能体工作流2335statistical-analysisk-dense-ai/scie…t-skillsGuided statistical analysis for research data - test selection, assumption checking, effect sizes, power analysis, Bayesian alternatives, and APA-formatted reporting. Use whenever a user wants to compare groups, test a hypothesis, analyze experimental or survey data, check statistical assumptions, compute required sample sizes, or write up results - even if they never name a specific test. Covers t-tests, ANOVA, chi-square, correlation, regression, non-parametric and Bayesian methods. For low-level model APIs, see the statsmodels and pymc skills.数据与研究2318
