pandas-profiling

Generates profile reports from a pandas DataFrame. The pandas df.describe() function is great but a little basic for serious exploratory data analysis.

For each column the following statistics - if relevant for the column type - are presented in an interactive HTML report:

• Essentials: type, unique values, missing values
• Quantile statistics like minimum value, Q1, median, Q3, maximum, range, interquartile range
• Descriptive statistics like mean, mode, standard deviation, sum, median absolute deviation, coefficient of variation, kurtosis, skewness
• Most frequent values
• Histogram
• Correlations highlighting of highly correlated variables, Spearman and Pearson matrixes

Installation

Using pip

You can install using the pip package manager by running

pip install pandas-profiling

Using conda

You can install using the conda package manager by running

conda install -c anaconda pandas-profiling

From source

Download the source code by cloning the repo or by pressing 'Download ZIP' on this page. Install by navigating to the proper directory and running

python setup.py install

Usage

The profile report is written in HTML5 and CSS3, which means pandas-profiling requires a modern browser.

Jupyter Notebook (formerly IPython)

We recommend generating reports interactively by using the Jupyter notebook.

Start by loading in your pandas DataFrame, e.g. by using

import numpy as np
import pandas as pd
import pandas_profiling

df=pd.DataFrame(
    np.random.rand(100, 5),
    columns=['a', 'b', 'c', 'd', 'e']
)

To display the report in a Jupyter notebook, run:

pandas_profiling.ProfileReport(df)

To retrieve the list of variables which are rejected due to high correlation:

profile = pandas_profiling.ProfileReport(df)
rejected_variables = profile.get_rejected_variables(threshold=0.9)

If you want to generate a HTML report file, save the ProfileReport to an object and use the to_file() function:

profile = pandas_profiling.ProfileReport(df)
profile.to_file(outputfile="output.html")

Python

For standard formatted CSV files that can be read immediately by pandas, you can use the profile_csv.py script. Run

python profile_csv.py -h

for information about options and arguments.

Advanced usage

A set of options are available in order to adapt the report generated.

• bins (int): Number of bins in histogram (10 by default).
• Correlation settings:
  • check_correlation (boolean): Whether or not to check correlation (True by default)
  • correlation_threshold (float): Threshold to determine if the variable pair is correlated (0.9 by default).
  • correlation_overrides (list): Variable names not to be rejected because they are correlated (None by default).
  • check_recoded (boolean): Whether or not to check recoded correlation (False by default). Since it's an expensive computation it can be activated for small datasets.
• pool_size (int): Number of workers in thread pool. The default is equal to the number of CPU.

Dependencies

• An internet connection. Pandas-profiling requires an internet connection to download the Bootstrap and JQuery libraries. I might change this in the future, let me know if you want that sooner than later.
