使用scipy的Pyinstaller。信号导入错误：DLL加载失败

Question

我使用PyInstaller 3.3、Python3.4编译了一个需要使用scipy的程序。信号函数，它导致了。exe在启动时立即崩溃。我一直在stack overflow和其他网站上搜索，试图包含正确的DLL，但没有结果。请帮助我确定是否需要在我的应用程序中包含一些特定的DLL。规格文件或包含其他一些隐藏的导入！

以下是我的PyInstaller命令：

pyinstaller --noupx --hidden-import=tkinter --hidden-import=scipy --hidden-import=matplotlib constantG_constantHz.py

下面是启动我的exe后命令提示符中相应的错误：

问题是很多丢失的dll。PyInstaller在查找大部分Smpy的dll时遇到了问题，所以我不得不指定了很多。我将在下面发布我的. spec文件，以防有人想看到/复制我必须引入的dlls。有些事情可能是不必要的，但它是有效的，所以我不会弄乱它。请确保您指向正确的目录为您的系统虽然-它不会是相同的，因为我的，所以不要只是复制/粘贴：）

Answer 2

我以前尝试过这些方法，但并没有解决我的问题。最后，我用这种方式解决了。

在命令（cmd）窗口中编译可执行文件（exe）文件时，我的命令编写如下：

pyinstaller -F --paths C:\Users\Desktop\Code\2018.04.23\venv\Lib\site-packages\scipy\extra-dll pdf_num_detect.py

希望这个小技巧能帮到大家。
