<p><strong>问题描述得越清晰，越有可能被快速解决。</strong></p> <ol><li>请确保你针对该问题使用了正确的模板。你可以选择 <em>Bug Report</em>、<em>Feature Request</em>、<em>Feedback about API Design</em>、<em>New model/pipeline/scheduler addition</em> 或空白问题。在打开 <a href="https://github.com/huggingface/diffusers/issues/new/choose" rel="nofollow">a new issue</a> 时，请务必选择正确的模板。使用类问题应发布在 <a href="https://github.com/huggingface/diffusers/discussions" rel="nofollow">GitHub Discussions</a> 中，而不是作为 issue 提交。</li> <li><strong>表述精确</strong>：为你的问题起一个贴切的标题。尽量用简洁的语言描述问题。提交问题时表述得越精确，理解并解决该问题所需的时间就越短。请确保每个 issue 只针对一个问题，不要将多个问题混在一起。如果你发现了多个问题，请分别提交多个 issue。如果你的问题是 bug，请尽可能精确地说明具体是什么 bug——不要只写“diffusers 中出现错误”。</li> <li><strong>可复现性</strong>：没有可复现的代码片段就等于没有解决方案。如果您遇到 bug，维护者必须能够<strong>复现</strong>该问题。请确保您包含一段可以复制粘贴到 Python 解释器中运行以复现问题的代码片段。请确保您的代码片段可以正常运行，<em>即</em>没有缺失的导入或指向图像的缺失链接等。您的 issue 应包含错误消息<strong>以及</strong>一段无需任何修改即可复制粘贴并复现完全相同错误消息的代码片段。如果您的 issue 使用了读者无法访问的本地模型权重或本地数据，则该 issue 无法解决。如果您无法共享您的数据或模型，请尝试创建一个虚拟模型或虚拟数据。</li> <li><strong>极简主义</strong>：在尽可能简洁的前提下，帮助读者尽快理解问题。删除所有与问题无关的代码和信息。如果发现了一个 bug，请尝试编写最简单的代码示例来复现该问题，而不是在发现 bug 后就将整个工作流直接粘贴到 issue 中。例如，如果你在训练模型时在某处遇到错误，应首先尝试确定是哪部分训练代码导致了该错误，并尝试用几行代码来复现它。请尽量使用虚拟数据，而不是完整的数据集。</li> <li><strong>背景</strong>：请告诉我们，在遇到该 bug 或需要该功能时，你正在做什么工作，例如基于 Diffusers 构建的应用、研究项目，或你运行用于在库中查找 bug 的智能体。一两句话即可，附上项目链接更佳。我们收到的 issue 和 PR 数量远超当前处理能力，因此背景信息有助于我们根据影响程度进行优先级排序。</li> <li>添加链接。如果你指的是某个特定的命名、方法或模型，请确保提供链接，以便读者更好地理解你的意思。如果你指的是某个具体的 PR 或 issue，请确保将其链接到你的 issue。不要假设读者知道你在说什么。你在 issue 中添加的链接越多越好。</li> <li>格式规范。请妥善格式化你的 issue，将代码格式化为 Python 代码语法，将错误信息格式化为普通代码语法。有关更多信息，请参阅 <a href="https://docs.github.com/en/get-started/writing-on-github/getting-started-with-writing-and-formatting-on-github/basic-writing-and-formatting-syntax" rel="nofollow">GitHub 官方格式文档</a>。</li> <li>请将你的问题视为一部精心撰写的百科全书中一个精彩的条目，而非一张待解决的工单。每一个新增的问题都是对公开知识体系的贡献。撰写一份条理清晰的问题报告，不仅能让维护者更轻松地解决你的问题，也有助于整个社区更好地理解该库的某个特定方面。</li></ol> <!--[1--><h2 class="relative group"><a id="how-to-write-a-good-pr"

issue，或者如果还没有人提出，就自己开一个，并在编写代码之前给维护者留出回应的时间。对我们来说效果最好的工作流程是：先开一个 issue，然后讨论解决方案，最后基于该讨论提交 PR。这让我们能够将时间集中在影响最大的 issue 上，在代码出现之前就就范围达成一致，并避免重复劳动。请在 PR 描述中提及 issue 编号（例如 <code>Fixes #1234</code>），以便将两者关联起来。</li> <li>像变色龙一样。理解现有的设计模式和语法，确保你新增的代码能够无缝融入现有代码库。与现有设计模式或用户界面存在显著差异的 Pull Request 将不会被合并。</li> <li>保持专注。一个拉取请求（pull request）应只解决一个问题，且仅解决该问题。请避免陷入“既然在添加功能，顺便也修复另一个问题”的陷阱。同时解决多个不相关问题的拉取请求会大大增加代码审查的难度。</li> <li>修复模式，而非孤例。一个问题可能横跨多个文件：如果同一个 bug 在代码库中反复出现，请搜索所有实例，并在一个 PR 中全部修复，同时明确且系统地界定范围（例如“修复所有调度器中的可变默认值”），而不是为每个实例单独提交一个 PR。</li> <li>您的拉取请求（pull request）标题应是对该贡献的摘要。若要表示工作正在进行中，请在标题前加上 <code>[WIP]</code> 前缀；这样可以避免重复劳动，并将该 PR 与已准备好合并的 PR 区分开来。</li> <li>请按照<a href="#how-to-write-a-good-issue">如何撰写高质量的 issue</a>中的说明，尝试组织并格式化你的文本。</li> <li>在提交 PR 之前，请先自行审查你的 diff。像评审者一样阅读它，并修复你发现的问题。我们强烈建议运行 <a href="https://github.com/huggingface/diffusers/blob/main/.ai/skills/self-review/SKILL.md" rel="nofollow"><code>self-review</code></a> 技能：它会执行与 <code>@claude</code> CI 评审者相同的评分标准。按照 <a href="#coding-with-ai-agents">使用 AI 智能体进行编码</a> 中的说明配置你的智能体，并遵循 <a href="#ai-assisted-and-agentic-contributions">AI 辅助和智能体贡献</a>。在描述中说明你有意保留未改动的发现，以便评审者知道这是你的决定，而非疏忽。</li> <li>确保现有测试通过。</li>

辅助与智能体贡献<!----></span></h3><!--]--><!----> <p>欢迎 AI 智能体为 Diffusers 做出贡献。我们建议您使用 Diffusers 的 <a href="https://github.com/huggingface/diffusers/blob/main/.ai/AGENTS.md" rel="nofollow">智能体指南</a> 来配置您的智能体，并使用相关的特定任务技能，例如 <code>model-integration</code> 和 <code>self-review</code>。按照上述说明安装插件（或单个技能），然后遵循指南来界定范围、实现、测试并审查您的贡献。您仍需负责理解、测试和维护 PR 中的更改。</p> <p>欢迎通过 AI 辅助进行贡献，但必须对其进行协调、限定范围并加以验证，以将审查工作量控制在可管理的范围内。未遵循这些准则的 PR 可能会被直接关闭，而不会进行详细审查。</p> <ul><li><strong>在提交 PR 之前请先进行协调。</strong>查找或创建一个 issue，查看相关的 PR（包括已打开和最近已关闭的），并在该 issue 上等待维护者的明确确认后再提交 PR。这能让我们有机会讨论范围、避免重复工作并确认实现方案。</li> <li><strong>修复模式，而非孤立问题。</strong> 如果你发现一个反复出现的问题，请在代码库中搜索类似的实例，并针对一个清晰、系统性的范围（例如“修复所有调度器中的可变默认值”）提交一个<em>单一</em>的 issue，而不是为每个单独实例提交多个 issue 或 PR。</li> <li><strong>在提交前进行自查。</strong> 运行 <a href="https://github.com/huggingface/diffusers/blob/main/.ai/skills/self-review/SKILL.md" rel="nofollow"><code>self-review</code></a> 技能——它会依据 <a href="https://github.com/huggingface/diffusers/blob/main/.ai/references/review-rules.md" rel="nofollow"><code>.ai/references/review-rules.md</code></a> 审查你的 diff，该文件与 <code>@claude</code> CI 审查员使用的标准一致——并处理其报告的问题。该技能只是一个辅助工具，并非权威，也可能出错。请重点关注那些你认为合理的阻塞性问题，并尽可能清理无用/未使用的代码。如果你不同意某条建议，可以将其留给审查员在 PR 打开后讨论——你分享的备注（见下文）会告知审查员这是你有意为之的决定。</li> <li><strong>分享你的自查笔记。</strong>请在 PR 中发布最终的自查报告——即反映你所提交 diff 的那一轮——将其放在描述中或作为评论，并包含你有意未修复的问题及其原因。这有助于审阅者了解哪些内容已经检查过、哪些决定是有意为之，通常也能省去几轮来回沟通。</li> <li><strong>保持 PR 沟通简洁。</strong> 审查者在你的 PR 中阅读的所有内容——描述、提交信息、评论和回复、代码注释——都必须让人类易于理解。如果是由你的 agent 起草的，不要只是粗略浏览。请仔细阅读，并要求 agent 修改，直到内容合理、简洁，且是你自己会写出的风格。你是你所发布的所有内容的作者。</li> <li><strong>Include in the PR description:</strong> <ul><li>指向维护者已确认该工作的 issue 或讨论的<strong>协调链接</strong>。</li> <li>你运行的 <strong>测试命令</strong> 及其结果（请粘贴相关输出，而不仅仅是“测试通过”）。</li> <li>如上所述，您的<strong>自我审查笔记</strong>（或包含这些笔记的 PR 评论链接）。</li></ul></li></ul> <p>如果您是模型作者，或属于官方维护某个模型的团队，我们鼓励您使用智能体来完成新模型的集成。请遵循该仓库的<a href="https://github.com/huggingface/diffusers/blob/main/.ai/AGENTS.md" rel="nofollow">推荐配置</a>，并使用<a href="https://github.com/huggingface/diffusers/blob/main/.ai/skills/model-integration/SKILL.md" rel="nofollow"><code>model-integration</code></a>技能。在提交 PR 之前，请先与维护者协调好范围——参见<a href="#10-adding-pipelines-models-schedulers">添加流水线、模型和调度器</a>。</p> <a class="!text-gray-400 !no-underline text-sm flex
