使用pyinstaller打包了一下文件(pyinstaller -F -n test.exe test.py)，运行test.exe报错

在网上找了很多资料，很难呀，博客比较少，就顺便写下来了。
看上面运行的报错信息，明细是缺少了mxnet (已经用红字表明)，有可能是pyinstaller 没有识别到mxnet，或者是其他的问题。
解决办法：
1. 重启电脑。 有可能是pyinstaller没有找到mxnet这个包，如果你是刚安装了pyinstaller没重启的话可以一试。
2.在打包程序的时候主动添加缺少的文件包
我这里缺少了mxnet，首先我就要去找到mxnet包的地方，我这里是 ：C:\Users\netpr1s0ner\AppData\Local\Programs\Python\Python37\Lib\site-packages\mxnet
然后再打包程序的时候这样输入：pyinstaller -F -n test.exe --add-data="C:\Users\netpr1s0ner\AppData\Local\Programs\Python\Python37\Lib\site-packages\mxnet\*;./mxnet" test.py
（如果不理解这句话是啥意思，先去百度一下 --add-data 参数格式，我这里懒得写了）
之后就可以正常运行了。
总结：缺少什么包就去添加什么包，一般这种方案都可以解决缺少包引发的错误问题。
