pyinstaller打包生成软件运行时出现缺少模块cython_blas的错误

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
