早就试了，一样的报错
要不您咨询一下百炼的客服试试，这个问题有些奇怪，我们之前自己内部测试以及现场活动时用户试用都没有遇到过这个问题，我也很好奇是什么原因导致的。
另外，您能用 http 调试工具例如 postman 来尝试发送请求看看能否成功吗？

langchain-community 模块明明有安装 还报找不到的错误。莫名奇妙
信心快被消耗完了
只是感觉poetry 不是很可靠，就按同样的步骤重新走一遍，结果报的错误 很可能不一样。
您有修改 pyproject.toml 文件吗？我们提供的 pyproject.toml 里面的 langchain-community 是引用的我们自己的仓库，如果修改了这一项会出现找不到 OceanBase VectorStore 的问题
好的，那说明模型调用服务正常开通了。我们拉个钉钉群沟通一下吧，我怎么能加上您的钉钉呢？
没有动，文件内容如下：
$ cat pyproject.toml

建议您克隆下面这个代码仓库 tongyi 分支的代码，并且按照这个仓库的 README 步骤进行操作
很棒
