通过pip 安装 报DLL的问题.python版本3.88 about api_python3

[lppgo]

ImportError: DLL load failed while importing dolphindbcpp: 动态链接库(DLL)初始化例程失败。

我也遇到这个问题。我在win10 python3.8 遇到相同的问题，反复测试好几次。最后切换安装python3.7.9 并对应使用dolphindb 3.17.4 发现可以运行

请问你的python是什么版本？

目前windows 版本的 DolphinDB Python API 支持 Python 3.6-3.8 版本，但仅支持 conda 环境下的 python 3.8；
请在conda环境下配置python3.8 > 3.8.0（ps：windows下，python 3.8.0 暂不支持 DolphinDB Python API），pip安装 Python API 后 import 。
