Pytorch环境下基于Transformer的滚动轴承故障诊断_轴承数据故障诊断pytorch

关于python的集成环境，我一般Anaconda 和 winpython 都用，windows下主要用Winpython，IDE为spyder（类MATLAB界面）。

winpython脱胎于pythonxy，面向科学计算，兼顾数据分析与挖掘；Anaconda主要面向数据分析与挖掘方面，在大数据处理方面有自己特色的一些包；winpython强调便携性，被做成绿色软件，不写入注册表，安装其实就是解压到某个文件夹，移动文件夹甚至放到U盘里在其他电脑上也能用；Anaconda则算是传统的软件模式。winpython是由个人维护；Anaconda由数据分析服务公司维护，意味着Winpython在很多方面都从简，而Anaconda会提供一些人性化设置。Winpython 只能在windows上用，Anaconda则有linux的版本。

抛开软件包的差异，我个人也推荐初学者用winpython，正因为其简单，问题也少点，由于便携性的特点系统坏了，重装后也能直接用。

请直接安装、使用winPython：WinPython download因为很多模块以及集成的模块

可以选择版本，不一定要用最新版本，否则可能出现不兼容问题。

下载、解压后如下

打开spyder就可以用了，里面自带pytorch.

开始步入正题，进行基于Transformer的滚动轴承故障诊断，Transformer模型就不多说了，很多论文都有介绍。

用的数据集是简单的西储大学数据集

 为了便于处理，转换为csv文件类型

关于Transformer模型，部分截图如下

训练

if __name__ == '__main__':
    train()

结果如下
