PathML

在本地计算病理学研究中,使用 PathML 加载切片、构建预处理和质量控制流程、管理 h5path 数据、量化多重免疫组化图像、构建空间图,并规划有界模型推理。

PathML 是什么?

PathML 是一个用于本地计算病理学研究的 Python 库,专为研究机构设计。它允许用户加载和切片全切片图像(WSI),使用内置的预处理管道(如 BoxBlur 和 TissueDetectionHE)进行组织检测和质量控制,并将结果保存到 .h5path 格式。该工具还支持多重免疫组化图像分析,包括使用 AnnData 和 DeepCell/Mesmer 模型进行细胞量化,并支持构建空间图(如 KNN、RAG、HACT),用于空间生物学分析。PathML 强调安全和隐私,要求用户验证数据授权、去标识化像素和元数据,避免使用直接标识符。技能文档提供了详细的安装步骤(Python 3.10-3.12)、稳定工作流程示例和八个研究步骤,包括本地清单、拆分、有界预处理和推理。该技能基于 PyPI 上发布的 PathML 3.0.5 版本,并包含多个本地 CLI 工具用于清单验证、管道规划和推理规划。

PathML 是做什么的?

范围与安全边界

在本地计算病理学研究中使用 PathML。它是研究软件(测试版),而非经过验证的医疗设备、诊断系统、临床决策支持工具或病理学家替代品。请勿使用输出结果对患者进行诊断、分级、分期或治疗。

病理学文件可能包含人脸、标签、病例编号、患者标识符、DICOM 标签、文件名或关联的临床数据。处理前:

  1. 确认授权、同意/豁免、数据使用条款和机构政策。
  2. 去标识化像素和元数据;将重标识密钥保存在分析工作区之外。
  3. 使用化名 patient_id、slide_id 和 specimen_id 值。不要在文件名、日志、.h5path 标签、模型卡或报告中放置直接标识符。
  4. 将输入、中间结果和输出保存在经批准的本地加密存储中。
  5. 在切片或拟合任何预处理步骤之前,按患者(然后按切片)进行拆分。

版本基线(已验证于 2026-07-23)

  • 可安装的稳定版本: PyPI pathml==3.0.5,发布于 2026-03-24。
  • v3.0.5 发布说明声明需要 Python 3.10-3.12,并停止支持 3.9。PyPI 未声明 Requires-Python,且仍保留过时的 3.8 分类器,因此请使用发布声明并测试确切环境。
  • GitHub 发布了 v3.0.6(2026-04-14)和 v3.0.7(2026-07-09),但截至本次审查,PyPI 上尚无这些版本的构件。v3.0.7 更新了 Torch/TorchVision/torch-geometric 和 ONNX 导出代码。请勿将这些源码依赖项与 3.0.5 wheel 混合使用。
  • ReadTheDocs /latest 标识自身为 3.0.5。此处示例已针对 v3.0.5 标签和 PyPI wheel 元数据进行了检查,而非未版本化的片段。
  • 本技能采用 MIT 许可证。PathML 本身采用 GPL-2.0 并提供上游商业许可选项;在再分发前请审查上游条款。

可复现安装

除非项目已测试过其他支持的解释器,否则使用 Python 3.11:

uv venv --python 3.11
source .venv/bin/activate
uv pip install "pathml==3.0.5"
python -c "import importlib.metadata as m; print(m.version('pathml'))"

PathML 3.0.5 声明没有包 extras:不要使用 pathml[all]。其基础发行版固定了一个大型科学/ML 栈,包括 Torch 2.8.0、ONNX 1.17.0、ONNX Runtime 1.17.x、OpenSlide Python 1.3.1、python-bioformats 4.1.0 和 python-javabridge 4.0.4。

在运行 uv 命令前安装原生前置依赖项:

# Debian/Ubuntu
sudo apt-get install openslide-tools gcc g++ libblas-dev liblapack-dev openjdk-17-jdk

# macOS
brew install openslide openjdk@17

# Windows OpenSlide 选项请参见上游文档
vcpkg install openslide

需要 Java/Bio-Formats 以支持广泛的多元数据格式后端。OpenSlide 更高效地处理常见的明场 WSI 格式。CUDA 是可选的,并且必须匹配固定的 PyTorch 构建;请遵循 PyTorch 的平台选择器,而不是猜测 CUDA wheel。请参见 references/image_loading.md。

稳定的最小工作流程

PathML 3.0.5 使用切片便利类和 SlideData.run()。它不提供 SlideData.from_slide(),并且 Pipeline 没有 run() 方法:

from pathml.core import HESlide
from pathml.preprocessing import BoxBlur, Pipeline, TissueDetectionHE

slide = HESlide("data/pseudonymous_slide.svs", backend="openslide")
pipeline = Pipeline(
    [
        BoxBlur(kernel_size=5),
        TissueDetectionHE(mask_name="tissue", min_region_size=5000),
    ]
)
slide.run(
    pipeline,
    distributed=False,
    tile_size=512,
    tile_stride=512,
    level=0,
    tile_pad=False,
)
slide.write("derived/pseudonymous_slide.h5path")

在完整运行前,先从一个有界的样本开始:

from itertools import islice

for tile in islice(slide.generate_tiles(shape=512, stride=512, level=0), 8):
    pipeline.apply(tile)
    assert tile.masks["tissue"].shape[:2] == tile.image.shape[:2]

切片使用 (i, j) = (行, 列) 坐标,位于所选金字塔层级。对于 OpenSlide,PathML 会将其内部映射到 0 层级坐标。记录层级和降采样率;稍后明确转换为 (x, y) 或微米坐标。

研究工作流程

  1. 本地清单。 验证清单,拒绝 URL/符号链接,仅检查允许列表中的技术元数据,并移除标识符。
  2. 冻结拆分。 在生成重叠切片、图、归一化参考或特征之前,将每位患者及其所有切片分配给一个拆分。
  3. 规划边界。 估算切片数量、RAM、输出大小和管道阶段。
  4. 试点预处理。 在代表性训练切片上检查组织掩码、空白/伪影标签、染色行为、边缘填充和空掩码情况。不要根据测试切片进行调整。
  5. 运行并保留坐标。 保留切片层级、(i, j)、降采样率、MPP、掩码名称、QC 决策以及失败/跳过的切片。
  6. 有目的地构建空间数据。 验证通道顺序、物理单位、实例标签、节点特征对齐、图边和细胞到组织的分配。
  7. 在有界批次中推理。 在未加载未知 pickle 检查点的情况下验证模型来源和校验和。保持预测与切片/瓦片坐标的关联,并使用文档化的规则拼接重叠区域。
  8. 报告来源和局限性。 包括包锁定文件、来源哈希、扫描仪、染色、参数、随机种子、拆分清单、模型卡、排除项和 QC。

默认无网络和明确同意门控

除非用户明确选择加入并了解端点和披露信息,否则不要实例化可下载类或设置数据集 download=True:

  • SegmentMIFRemote 在构造时会从 https://huggingface.co/pathml/test/resolve/main/mesmer.onnx 下载一个 ONNX 文件,然后在本地运行推理。稳定来源不会上传图像像素。该请求仍会披露网络元数据(如 IP 地址和标头),并创建 temp.onnx;没有内置的校验和或离线标志。
  • 已弃用的 SegmentMIF 导入本地 DeepCell Mesmer,但 DeepCell 模型初始化可能需要单独提供的权重。它不是 PathML 的附加包,也不是首选的稳定 API。
  • RemoteTestHoverNet 从 Hugging Face 下载模型。
  • PanNukeDataModule(download=True) 联系 Warwick;DeepFocusDataModule 联系 Zenodo。两者均默认 download=False。

在任何未来的托管预测调用之前,说明确切目标、像素通道/区域、元数据、标识符、保留期限、法律依据和保障措施;获得明确同意;切勿默认发送 PHI。优先使用经过审查和校验的本地模型构件以及本地推理。

模型代码安全

  • PyTorch model.eval() 意味着模块的评估模式;它不是 Python 危险的 built-in 求值器。切勿使用 Python 动态求值或执行。
  • 不要将本地文件命名为 pathml.py、torch.py、onnx.py 或根据标准库命名;影子模块可能静默更改导入。
  • PathML 的 EntityDataset 使用 weights_only=False 加载 .pt 对象。切勿打开不受信任的图/检查点。将基于 pickle 的管道和 .pt 文件视为可执行代码。
  • ONNX 比 pickle 更安全,但并非本质上可信赖。验证来源、SHA-256、预期输入/输出模式、文件大小和运行时限制;对第三方模型使用隔离。

捆绑的本地 CLI

所有助手拒绝 URL 和符号链接,限制输入/工作,使用严格的 JSON,避免网络访问,并且即使未导入 PathML 也可使用 --help 查看帮助:

python scripts/slide_manifest.py validate --manifest manifest.csv --root .
python scripts/slide_manifest.py inspect --slide data/example.svs --root .
python scripts/plan_pipeline.py --width 100000 --height 80000 --tile-size 512 --stride 512
python scripts/image_qc.py synthetic --width 256 --height 256
python scripts/validate_spatial_schema.py graph --input graph.json --root .
python scripts/validate_spatial_schema.py multiplex --input cells.csv --root .
python scripts/plan_inference.py --tile-count 4000 --batch-size 16 --height 256 --width 256

推理规划器仅读取数字或一个有界的 JSON 模型卡;它从不导入模型框架或打开检查点。

biopython

Comprehensive molecular biology toolkit. Use for sequence manipulation, file parsing (FASTA/GenBank/PDB), phylogenetics, and programmatic NCBI/PubMed access (Bio.Entrez). Best for batch processing, custom bioinformatics pipelines, BLAST automation. For quick lookups use gget; for multi-service integration use bioservices.

bioservices

Unified Python interface to 40+ bioinformatics services. Use when querying multiple databases (UniProt, KEGG, ChEMBL, Reactome) in a single workflow with consistent API. Best for cross-database analysis, ID mapping across services. For quick single-database lookups use gget; for sequence/file manipulation use biopython.

bulk-rnaseq

End-to-end bulk RNA-seq orchestrator — takes raw FASTQ reads through QC and trimming (FastQC, fastp/Trim Galore), alignment and quantification (STAR, Salmon, featureCounts), assembles a gene-level counts matrix, then hands off to differential expression (pydeseq2), pathway/GSEA enrichment (pathway-enrichment), and publication figures (scientific-visualization). Use whenever the user has bulk RNA-seq reads or quant output and wants a complete, reproducible differential-expression workflow — e.g.

cellxgene-census

Query the CZ CELLxGENE Census programmatically for versioned public single-cell and spatial transcriptomics data. Use when you need population-scale cell metadata, gene expression slices, Census summary counts, source H5AD URIs/downloads, embeddings, spatial Census data, or reference atlas comparisons across organisms, tissues, diseases, assays, and cell types. For analyzing your own local single-cell data use scanpy, anndata, or scvi-tools.

cirq

Google quantum computing framework. Use when targeting Google Quantum AI hardware, designing noise-aware circuits, or running quantum characterization experiments. Best for Google hardware, noise modeling, and low-level circuit design. For IBM hardware use qiskit; for quantum ML with autodiff use pennylane; for physics simulations use qutip.

citation-management

Comprehensive citation management for academic research. Search OpenAlex, PubMed, and Google Scholar for papers, extract accurate metadata, validate citations, and generate properly formatted BibTeX entries. This skill should be used when you need to find papers, verify citation information, convert DOIs to BibTeX, or ensure reference accuracy in scientific writing.

clinical-decision-support

Prepare and validate research-only clinical decision-support evaluation, evidence-profile, cohort, survival, biomarker/model, privacy, and governance artifacts. Use for aggregate or synthetic research documentation and traceability—not patient care or live clinical operation.

clinical-reports

Create safety-bounded draft structures and run local deterministic checks for clinical case, diagnostic, trial, safety, and aggregate research reports. Use only with synthetic, de-identified, or aggregate inputs and verified source-fact manifests; every output requires qualified review.
