我正在使用 Gemini 作为 LLM，我注意到日志中有很多错误，似乎是来自 embeddings backfill 任务。
Job exception: Net::HTTPBadResponse
/var/www/discourse/plugins/discourse-ai/app/jobs/scheduled/embeddings_backfill.rb:122:in `populate_topic_embeddings’
根据上面的架构图，它应该只在新主题上运行，但似乎有一个 backfill 任务也在对现有主题运行。这本身其实是件好事，因为它也有助于处理现有主题。
我的疑问与限制有关。如果 Gemini 每分钟限制为 60 个查询，我怀疑阈值可能导致了错误（有没有办法确认？）。
当达到阈值时，discourse 会在一段时间后重试失败主题的 embeddings 吗？如果是，多久重试一次，持续多久？如果不是，有没有办法手动触发相关主题的 backfill 任务，以重新处理未处理的主题？
您可以使用隐藏的站点设置 ai_embeddings_backfill_batch_size 来调整您的回填速率。您可以将其设置为 50 以符合免费 Gemini 的限制。
谢谢。我刚做完了，我猜应用程序不需要重启。也许将此设置暴露在管理员面板的 AI 设置页面下是个好主意，因为我怀疑不同的模型可能会提供分级限制。
如果 AI 模块因任何原因（例如连接性或身份验证丢失）遇到限制或失败，在没有任何干预的情况下，我可以假设 AI 模块会无限期地继续尝试回填未处理的主题吗？
抱歉，这似乎不起作用。我仍然看到错误数量 Job exception: Net::HTTPBadResponse 在不断增加。我尝试重启系统，并在 Rails 中验证了回填批次数量设置为 50。我还能在这里做什么/检查什么？
是的
使用您的 API 密钥运行以下命令的输出是什么？
curl https://generativelanguage.googleapis.com/v1beta/models/embedding-001:embedContent?key=API_KEY_GOES_HERE -H 'Content-Type: application/json' -X POST -d '{ \"content\": { \"parts\":[{ \"text\": \"Why use Discourse for my online community?\"}]}}'

@Falco，您对这里发生的情况有什么看法？错误似乎没有停止。
发现 Gemini Embeddings API 对请求正文有 10k 字节的硬限制，即使在 2048 个 token 限制内也可能超出 
此 PR 将解决此问题
好的，我在管理员升级面板中更新了 discourse 插件。但不幸的是，它仍然在抛出错误：

这解决了我的安装问题，您确定是在 PR 合并 之后 更新的吗？而且这些错误是在该更改合并之后发生的吗？
嗯，昨晚从 Admin Upgrade 面板更新的。现在显示的是这样：
PR commit 指向 aabff87
您的 commit 在此之后 4 个 commit，是 a1f1067，但 discourse 说插件是最新的。我甚至尝试重启机器，但它仍然显示插件是最新的。
我需要更改分支或其他东西吗？如何强制 discourse 安装插件的最新 commit？
您是否碰巧在使用 stable 分支运行 Discourse？这会将插件锁定在旧提交上。我不建议将 AI 插件与 stable 一起使用，太多的活动部件需要新的核心钩子。
切换到 tests-passed 似乎升级了所有插件并解决了问题。
我之前因为 tests-passed 的一些问题导致停机，不得不从 tests-passed 切换到 stable。我得说，使用 tests-passed 需要管理员相当精通，并且他们可能会遇到问题（就像我之前遇到的 smtp TLS 问题和其他一些问题），并且需要擅长调试和深入研究。它不是一个“设置好就不用管”的分支。
不过我完全理解为什么我需要使用 tests-passed 才能使用这些新的 AI 插件。很棒的工作！迫不及待想进一步探索它。
