一.用PyInstaller打包PyQt5应用
打包时会自动将依赖库都打打包进去！所以体积不小。。
安装：pip3 install pyinstaller
代码：
直接在命令行下操作
常用：pyinstaller -Fw python文件名
pyinstaller -Fw Calc. py
-W:不显示终端
-F:将所有的库打包成-个单独的文件
bug：
from importlib_metadata import PackagePath as _PackagePath
ImportError: cannot import name 'PackagePath' from 'importlib_metadata' (D:\anaconda\lib\site-packages\importlib_metadata\__init__.py)现在pyinstaller是不支持python3.6的，正在完善中，所以可以去GitHub下载最新版的使用，戳这里
下开发版。
尝试了开发版，还是同样的错误！！！心态炸了！！！
看到一句话：一定要把pip升级成最新版的pip在安装pyinstaller哈。要不然可能会出现莫名奇妙的问题。
试过之后，还是不行！！！！
早晨突然看见anaconda没有被激活
于是开始激活,戳这里
激活之后重新打开cmd输入python发现还是出警告。。。。
最后最后，发现是anaconda的问题。。。我换了一个python原生的编译器下的pyinstaller没问题。。。当然之前的问题我还是不会解决。。。
在我的原生python下装上相应的包，再打包即可成功，会在当前目录生成三个文件夹和一个spec文件，exe文件在dist中
二.使用PyQtGraph进行数据可视化
代码：
pyqtgraph_pyqt.py
# -*- coding: utf-8 -*-
# Form implementation generated from reading ui file 'pyqtgraph_pyqt.ui'
#
# Created by: PyQt5 UI code generator 5.9.2
