探索性数据分析工具。
edap的Python项目详细描述
edapy是分析新数据集的第一个资源。
安装
$ pip install git+https://github.com/MartinThoma/edapy.git
对于pdf部分，您还需要pdftotext：
$ sudo apt-get install poppler-utils
用法
$ edapy --help
Usage: edapy [OPTIONS] COMMAND [ARGS]...
edapy is a tool for exploratory data analysis with Python.
You can use it to get a first idea what a CSV is about or to get an
overview over a directory of PDF files.
Options:
--version Show the version and exit.
--help Show this message and exit.
Commands:
csv Analyze CSV files.
images Analyze image files.
pdf Analyze PDF files.
工作流程如下：
edapy pdf find --path . --output results.csv创建一个results.csv为你。此results.csv包含有关path目录。edapy csv predict --csv_path my-new.csv --types types.yaml将启动/ 继续一个过程，在这个过程中，用户被引导通过一系列问题。在 这些问题，用户必须决定使用哪一个分隔符quotechar 以及列具有哪些类型。edapy生成可用于加载csv的types.yaml文件 使用df = edapy.load_csv(csv_path, yaml_path)的其他应用程序。
示例类型.yaml
对于Titanic Dataset，结果是
types.yaml如下所示：
columns:
- dtype: other
name: Name
- dtype: int
name: Parch
- dtype: float
name: Age
- dtype: other
name: Ticket
- dtype: float
name: Fare
- dtype: int
name: PassengerId
- dtype: other
name: Cabin
- dtype: other
name: Embarked
- dtype: int
name: Pclass
- dtype: int
name: Survived
- dtype: other
name: Sex
- dtype: int
name: SibSp
csv_meta:
delimiter: ','
然后，运行示例如下：
$ edapy csv predict --types types_titanik.yaml --csv_path train.csv
Number of datapoints: 891
