Pyinstaller numpy“英特尔MKL致命错误:无法加载mkl_intel_thread.dll" [英] Pyinstaller numpy "Intel MKL FATAL ERROR: Cannot load mkl_intel_thread.dll"

问题描述

我是python应用程序的新手.我正在尝试使用pyinstaller构建我的python GUI应用程序. 我的应用程序取决于以下软件包:PyQt4，numpy，pyqtgraph，h5py. 我正在使用WinPython-32bit-3.4.4.1.

I'm new with python apps. I'm trying to build my python GUI app with pyinstaller. My app depends on the following packages: PyQt4, numpy, pyqtgraph, h5py. I'm working with WinPython-32bit-3.4.4.1.

我使用以下命令构建应用程序:

I build the app with this command:

pyinstaller --hidden-import=h5py.defs --hidden-import=h5py.utils --hidden-import=h5py.h5ac --hidden-import=h5py._proxy VOGE.py

我使用pyinstaller创建的dist目录中的exe文件启动我的应用程序，在程序调用numpy并因以下错误而崩溃之前，它似乎运行良好:

I launch my app with the exe file in the dist directory created by pyinstaller and it seems work fine until the program call numpy and crash with this error:

英特尔MKL致命错误:无法加载mkl_intel_thread.dll

Intel MKL FATAL ERROR: Cannot load mkl_intel_thread.dll

软件目录中不存在mkl_intel_thread.dll；但是将文件复制到程序的根目录后，我遇到了同样的错误

The mkl_intel_thread.dll is not present in the software directory; but with the file copied in the root dir of the program I got the same error

感谢您的帮助

推荐答案

我创建了hook-numpy.py来解决此问题:

I created a hook-numpy.py to deal with this problem:

from PyInstaller import log as logging 
from PyInstaller import compat
from os import listdir

libdir = compat.base_prefix + "/lib"
mkllib = filter(lambda x : x.startswith('libmkl_'), listdir(libdir))
if mkllib <> []: 
   logger = logging.getLogger(__name__)
   logger.info("MKL installed as part of numpy, importing that!")
   binaries = map(lambda l: (libdir + "/" + l, ''), mkllib)

就我而言，conda正在安装mkl库以加快numpy和scipy的速度.

In my case, conda is installing the mkl libraries to speed up numpy and scipy.
