pyinstaller打包生成软件运行时出现缺少模块cython_blas的错误(总结就是缺少依赖文件pyd,注意命名规则)

关键点是找到缺失的依赖文件pyd，以及命名方式。加油！

ImportError: No module named cython_blas
start_ga_wfLayout returned –1

start_ga_wfLayout是打包生成的exe文件名称。上面显示在执行start_ga_wfLayout时找不到模块cython_blas.

使用的软件版本是：pyinstaller 3.0 + anaconda 2.3.0

问题分析：

根据提示找到目录：D:\Anaconda\Lib\site-packages\scipy\linalg

发现里面既有_decomp_update.pyd，也有cython_blas.pyd，同时在打包生成的dist\start_ga_wfLayout目录下存在scipy.linalg._decomp_update.pyd，这说明问题出现在pyinstaller打包过程中：没有将cython_blas.pyd打包。

如果直接将cython_blas.pyd拷贝到打包目录下，问题仍然存在。

解决方法：

根据scipy.linalg._decomp_update.pyd的命名规则，应该将cython_blas.pyd修改成scipy.linalg.cython_blas.pyd

命名规则可以参考python packages，如sound/effects/echo.py引用方法：import sound.effects.echo
