问题描述 python环境下安装cpu版本pytorch,安装成功,但是导入出错。 报错如下 解决方法 参考博客,大家解决方法大概有:升级numpy、添加.dll文件到环境变量,均没有成功。本地python版本为python3.6.0,升级为python3.6.5版本,继续导入: 报错如上,大概是说

Furthermore, the KNN classifier also showed the least mean squared error of 0.016. This shows that the KNN classification method yields the highest accuracy and lowest error rate for classifying pap smear images into normal and abnormal cells. Chen et al.21 proposed a method that uses two ...
