PyQt5 import QtCore ImportError

import QtCore的时候出错

from PyQt5 import QtCore
ImportError: DLL load failed while importing QtCore: 
  The specified procedure could not be found.

问题是 pip 安装的PyQt和其他package版本不对
最好使用conda进行安装

pip uninstall pyqt5
# pip uninstall pyqt5-tools
# pip uninstall pyqt5-plugins
conda install -c anaconda pyqt

也是我下面这个回答

其他问题：

import matplotlib
matplotlib.use("Qt5Agg")
import matplotlib.pyplot as plt

raise ImportError("Failed to import any qt binding") 
ImportError: Failed to import any qt binding

也是同样的原因

下面是网上其他的答案，我试了基本都没用

重新创建一个环境

将Python3.dll拷贝到执行程序所在目录，调试执行，一切正常，问题解决。
