作为Python中经典的机器学习模块,sklearn围绕着机器学习提供了很多可直接调用的机器学习算法以及很多经典的数据集,本文就对sklearn中专门用来得到已有或自定义数据集的datasets模块进行详细介绍; datasets中的数据集分为很多种,本文介绍几类常用的数据集生成方法,本文总结的所有内容你都可以在sklearn的官网: http://scikit...
# -*- coding: utf-8 -*- import argparse parser = argparse.ArgumentParser() subparsers = parser.add_subparsers() # 每个子命令都要添加这个参数, 用于区分当前运行的是哪个子命令 KEY_CM_ACTION = 'cm_action' ARG_PREFIX = '--' SUB_COMMAND_INIT = 'init' ARG_INIT_NAME = 'name' ARG_INIT...
python setup.py build_ext --inplace python setup.py install 以上命令会在当前目录下生成构建所需的文件,并将CMake扩展安装到Python环境中。 总结起来,使用CMake扩展setuptools的过程包括以下几个步骤: 确保CMake和setuptools已经安装在系统中。 创建一个CMakeLists.txt文件来描述CMake的构建过程。 使用CMake生...

第2 个参数是Python 元组,用于存储游标中返回的字段列表。为了提高游标的性能,最好的做法是在游标中限制字段的个数,只返回完成任务所需的字段。在这个例子中,指定返回Facility 和Name字段, SearchCursor 对象存储在名为cursor 的变量中。在with 语句块中,使用for 循环来遍历返回的学校,也使用了sorted ()函数对游标...
# Top-level Makefile for Python # # As distributed, this file is called Makefile.pre.in; it is processed # into the real Makefile by running the script ./configure, which # replaces things like @spam@ with values appropriate for your system. # This means that if you edit Make...
