其实torch.rand在torch_C._VariableFunctions这个模块中,torch.rand不是一个python的函数,只是一个模块中方法的名称,通过torch.rand调用torch模块中的rand方法,而这个模块是通过python的C/C++拓展机制生成的,实际中torch.rand对应的代码是通过一个yaml文本自动生成的。 这个文件是一个自动生成代码函数的参数列表,Pytorch...

python读取与写入csv,txt格式文件 在数据分析中经常需要从csv格式的文件中存取数据以及将数据写书到csv文件中.将csv文件中的数据直接读取为dict类型和DataFrame是非常方便也很省事的一种做法,以下代码以鸢尾花数据为例. csv文件读取为dict 代码 # -*- coding: utf-8 -*- import csv with open('E:/iris.csv'...
