Dataset 存储样本及其对应的标签， DataLoader 在 Dataset 基础上封装了一个可迭代的对象，以方便访问样本。
如果没有列名,设置参数header=None 真的实战的时候还是得用Dataset类+Dataloader读取自己的数据集,详见: Dataset类:https://www.cnblogs.com/xjl-ultrasound/p/18337058 Dataloader:https://www.cnblogs.com/xjl-ultrasound/p/18339035 2、处理缺失值NaN 比较常用的是 插值(补!) (1)用均值补inputs = inputs.fill...

把他们都集中管理起来，并且提供一个程序pip，这样可以直接在命令行里直接提供pip install xxx这样的代码...

『技术随手学』解决 pip conda install 网络故障中断 我也想能把你照亮,在你的生命中留下阳光 0.引子 在用pip或者conda安装一些包时有时会因为网络原因导致下载失败,进而无法安装。一般的解决方法就是换源,或者重复安装。 在本篇文章,将使用一个简单高效的方式来解决这个问题。整体思路很简单,把包下载到本地,在...
