I deployed dify (including API and web) on my macOS, and I tried to set my API Key in "Settings Model Provider TONGYI". When I clicked "Save", the page reported an error "parameter incrementar_output only support stream call", involving the following interfaces:“ http://localhost:5001/console/api/workspaces/current/model -Providers/tongyi ", the interface response is as follows: {
"code": "invalid_param",
"message": "parameter incremental_output only support stream call",
"status": 400
}
How can I solve this problem?

I noticed that the latest main branch has already addressed this issue by changing incremental-output=True to incremental-output=stream in core/model_runtime/moder_viewers/tongyi/llm/llm.py

参照#13620

在dify网页版使用通义千问的api（阿里云百炼）也会有这个问题，目前试了下好像没修复；你用的是本地部署dify吗？

应该是已经修复了吧。我本地部署的，你看下你用的是哪个版本的。master版本core/model_runtime/moder_viewers/tongyi/llm/llm.py下已经将incremental-output设置成了stream. 可以看下我上边的截图。我本地使用的是0.15.3，没有这个问题

I have the same problem.

可以参考下我上边的截图，去源码看下是否设置成stream. 历史版本可以手动设置下

0.15.3版本没有问题，升级到1.0.0就是这个问题了

0.15.3版本没有问题，升级到1.0.0就是这个问题了

嗯，看了下是代码变了。我之前本地使用的是master版本，当时官方是解决了这个问题的。有merge记录#13620
1.0.0有问题给他们提bug,hh

I checked the code, and the fix reverted in the new dify-official-plugins.
