dify 1.0.1无法在ollama下新增LLM模型

原来在0.15很正常，升到1.0.0之后就不行了，再后来1.0.1出来后，以为问题都解决了，没想到还是有问题。

具体是：添加ollama是容易了，但是添加模型（比如deepseek）还是不行。表现为点"保存"后，按钮一直灰色无响应，浏览器并不锁死。看后台进程，在一段时间后（超时）出来红色的错误：

以为是dify有问题，或者以前残留的数据有原因，做了一切能做的，包括删除项目，清除存储文件，甚至docker存储的虚拟磁盘都删了，还是不行。

后来参阅一篇文章《【踩坑】pip安装依赖卡在Installing build dependencies ...》，地址：https://blog.csdn.net/m0_51371693/article/details/144268469

有所触动，升级了一下numpy和pip的版本:

复制代码

再添加LLM模型居然立即成功了。看来是pip版本过低了？我的python版本:

复制代码

PS C:\Users\Admin> py

是装了好久的，看来是大数据变化太快了。下图是添加deepseek成功的样子：

希望给有遇到类似情况的朋友参考。
