环境信息 #

• Python版本：3.10.12
• 操作系统：Windows 11
• typing_extensions版本：4.9.0

解决方案 #

方案1：降级typing_extensions到兼容版本 #

Iterator和AsyncIterator在Python 3.10中已纳入标准库typing模块，而typing_extensions 4.5.0及以上版本移除了这些已标准化的类型，导致openai旧版本导入失败。执行以下命令降级：

!pip uninstall -y typing_extensions
!pip install typing_extensions==4.4.0

方案2：升级openai到最新版本 #

openai后续版本已修复该导入路径问题，直接升级即可：

!pip install --upgrade openai
