cli-dataanalyze's Issues

【问题】

文件来源：READMED.md

缺乏工具版本说明

  • 补充 requirement.txt ，放在主目录

查看文件类型

  • 如果 csv 文件的编码是 GB 18030/ GBK，该文件包含中英文、数字字符、甚至有字形表情符（ O(∩_∩)O~），用 file 不能识别，显示 ISO-8859 text

查看文件类型、描述数据，不能解决 utf-8 编码

  • 错误：Your file is not "utf-8" encoded. Please specify the correct encoding with the -e flag. Use the -v flag to see the complete error.

filename 未统一

  • 有些地方用 ACMETelephoneABT.csv，有些用 filename，建议统一使用filename，根据实际情况，标示采用的数据名称（比如ACMETelephoneABT.csv）

各列变量类型效果

  • 期望效果像 Pandas 那样，左边是列名称，右边是数据类型
  • 运行效果尾部有未知符，请确认
 33. churn
    <class 'bool'>
��
�2�

缺失值效果

  • 期望显示缺失数量与百分比

【文档说明】

  • _src文件夹存放 code ，输出的结果直接在 datacleaned.md对应位置补充
  • data文件夹存放需分析的 data

输出结果参考

参见《Fundamentals of Machine Learning for Predictive Data Analytics》 第 9 章 Data Preparation
