LatchBio 集成

当前基线

本技能针对 Latch SDK 2.76.8,发布于 2026 年 7 月 10 日。该软件包 元数据支持 Python 3.9–3.12,并声明了 Python 3.9+。

当指南与 SDK 不一致时,以已安装的包及其变更日志为准。一些 Latch 指南保留了较旧的 Python 范围或 特定兼容性的预发布版本锁定,特别是 Snakemake v2 教程。 切勿混合使用不同版本的命令或导入,除非检查了它们的版本要求。

何时使用

使用本技能可以:

  • 创建或维护 Python SDK 工作流和任务图
  • 打包并注册 Python、Nextflow 或 Snakemake 管道
  • 配置任务的 CPU、内存、存储、GPU、缓存、重试和超时
  • 通过 LPath、LatchFile、LatchDir 或 CLI 操作 Latch Data
  • 读取或更新 Latch Registry 项目、表和记录
  • 设计工作流表单、启动计划、样本表、消息和结果链接
  • 使用 latch register --staging 和 latch develop 进行登台和调试工作流镜像
  • 通过 Python 或 Latch MCP 启动和监控工作流
  • 发现并使用即用型 Latch 工作流

导航到正确的参考

只读取任务所需的参考:

需要参考
Python 工作流、任务、映射、条件、缓存references/workflow-creation.md
LPath、遗留文件类型、Latch URL、数据 CLIreferences/data-management.md
Registry 读取、事务、样本表references/registry.md
CPU、内存、存储、GPU、动态资源references/resource-configuration.md
Nextflow 和 Snakemake 打包references/nextflow-snakemake.md
元数据、表单、启动计划、消息、自动化references/ui-and-automation.md
注册、开发、执行、监控references/operations-and-debugging.md
即用型工作流和 latch.verifiedreferences/verified-workflows.md
远程 MCP 设置和工具工作流references/latch-mcp.md

在依赖某个符号之前,针对目标 SDK 版本运行 scripts/inspect_latch_sdk.py。 它仅执行本地导入,不会进行身份验证或发起网络请求。

安装和身份验证

对于可重现的环境:

uv venv --python 3.12
source .venv/bin/activate
uv pip install "latch==2.76.8"

在 Windows 上,使用 WSL 来处理文档中描述的 Linux 工作流工具。

通过支持的 OAuth 流程进行身份验证;不要手动读取、打印、复制或 解析 ~/.latch/token:

latch login
latch workspace

当已知数字 ID 时,非交互式地选择一个工作空间:

latch workspace --id 12345

latch login 凭据用于 SDK 和 CLI。Latch MCP 使用单独的 OAuth 授权,其凭据不能用于一般的 SDK 访问。

快速路径

创建并远程注册维护的子进程模板:

latch init covid-wf --template subprocess
latch register --yes --open covid-wf

远程镜像构建是默认设置。仅当本地 Docker 守护进程可用且有意的本地构建时,才使用 --no-remote。

最小化 Python 工作流

保持工作流主体声明性:调用任务并返回其承诺。 在任务内部执行计算和副作用。

from latch import small_task, workflow


@small_task
def reverse_complement(sequence: str) -> str:
    table = str.maketrans("ACGTacgt", "TGCAtgca")
    return sequence.translate(table)[::-1]


@workflow
def reverse_complement_workflow(sequence: str) -> str:
    """返回 DNA 序列的反向互补。"""
    return reverse_complement(sequence=sequence)

当生成的界面需要自定义标签、分区、验证规则、样本表或文档链接时,使用 @workflow(metadata)。 使用 LatchFile 或 LatchDir 进行自动的任务输入暂存和输出上传;使用 LatchPath 进行命令式的远程路径操作。

推荐的开发周期

  1. 检查兼容性

    • 确认已安装的 SDK 和 Python 版本。
    • 确定项目是 Python、Nextflow、遗留的 Snakemake 标志路径,还是单独锁定的 Snakemake v2 教程路径。
  2. 定义类型化接口

    • 为每个工作流和任务输入输出添加类型注解。
    • 保持模块导入时间没有网络调用、数据突变和秘密检索。隔离文档记载的异常,例如 workflow_reference,它在其装饰器被评估时解析活动工作空间。
    • 使用数据类和枚举表示结构化参数。
  3. 配置元数据和资源

    • 使元数据参数键与工作流签名匹配。
    • 从命名任务装饰器开始,然后仅在测量要求证明其合理性时使用 custom_task。
  4. 在执行镜像中验证

    全新的 Nextflow 和 Snakemake 项目在暂存前必须生成其 版本兼容的 Python 入口点。在 SDK 2.76.8 中, 暂存分支不会从 --nf-script 或 --snakefile 生成入口点。

    latch register --staging .
    latch develop .
    

    更改 Dockerfile 或依赖项后,重新运行暂存注册。 开发容器内部所做的编辑不会同步回来。

  5. 慎重注册

    latch register --yes --open .
    

    有用的控制选项:

    latch register --workspace-id 12345 .
    latch register --mark-as-release .
    latch register --workflow-module wf.custom_entrypoint .
    

    重复注册退出状态为 2;这与构建失败不同。

  6. 仅在审查成本和参数后启动

    • 优先使用 Console 或 Latch MCP 进行交互式操作。
    • 优先使用 latch_cli.services.launch.launch_v2 进行 Python 自动化。
    • 不要使用已弃用的 latch launch CLI 作为新的集成模式。
  7. 监控和验证

    • 检查终端状态、任务日志、结果链接和科学输出。
    • 将成功的编排视为必要的但并非充分的科学验证。

操作安全

  • 在启动付费计算(尤其是 GPU 或大批量运行)之前请求确认。
  • 在执行 LPath.rmr、latch rmr、Registry 删除或覆盖共享目标之前请求确认。
  • 切勿记录密钥、SDK 令牌、签名 URL 或秘密值。
  • 仅在任务内部调用 get_secret(),将返回值仅用于其预期服务,并且永远不要将其作为工作流输出返回。
  • 不要将不受信任的字符串传递给 shell 命令。优先使用参数列表和 subprocess.run(..., check=True)。
  • 为发布版本锁定 SDK 和工作流依赖项。仅在审查变更日志并重新运行暂存测试后升级。
  • 将生成的文件视为生成的:自定义文档记载的扩展文件,而不是编辑会被 CLI 覆盖的输出。

检查已安装的 SDK

从本技能目录执行:

uv run --no-project --python 3.12 --with "latch==2.76.8" \
  python scripts/inspect_latch_sdk.py

使用 JSON 输出进行自动比较:

uv run --no-project --python 3.12 --with "latch==2.76.8" \
  python scripts/inspect_latch_sdk.py --json

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.
