本人在Ubuntu 18.04 x64操作系统上将vnpy更新到2.10版本，所需的依赖已全部安装，cython是通过源码编译安装的，并且确认工作正常。vnpy升级过程中没有任何问题，在启动时，terminal有“Faile to import cython option pricing model, please rebuild with cython in cmd.”的报错。程序能正常启动运行，请教各位大神：该报错是什么问题导致的？该如何解决？万分感谢~

cython定价模型需要自己下载vn.py源代码，对vnpy/app/option_master/pricing下的cython代码重新编译即可

我在 vnpy/app/option_master/pricing/cython_model/binomial_tree_cython 目录下运行了 python setup.py build_ext --inplace 出现的警告,控制台还是有Faile to import cython option pricing model, please rebuild with cython in cmd. 的警告是为什么呢大佬?

我重新在那三个目录下运行了 python setup.py build_ext --inplace 显示running 中,但是我重新调试启动面板还是出现 terminal有“Faile to import cython option pricing model, please rebuild with cython in cmd.”的报错(vnpy-master) baishaojie@macdeiMac-Pro binomial_tree_cython % python setup.py build_ext --inplace running build_ext

这个是Warning提醒信息，如果是编译失败应该会有Error报错，请找到后贴下
Ubuntu22.04环境，anaconda包
到 vnpy_optionmaster项目或者gitee上，下载 cython_model 目录。
下载完成后，进入该目录下的 binomial_tree_cython， black_76_cython， black_scholes_cython 三个目录中。分别运行：
python setup.py build_ext --inplace
复制新生成同目录名一样的.pyx .so文件，共6个文件，到/site-packages/vnpy_optionmaster/pricing/目录下。

感谢，你这个方法，我在mac上也解决了这个问题
