## What is whylogs

whylogs is an open source library for logging any kind of data. With whylogs, users are able to generate summaries of their datasets (called _whylogs profiles_) which they can use to:

1. Track changes in their dataset
2. Create _data constraints_ to know whether their data looks the way it should
3. Quickly visualize key summary statistics about their datasets

These three functionalities enable a variety of use cases for data scientists, machine learning engineers, and data engineers:

- Detect data drift in model input features
- Detect training-serving skew, concept drift, and model performance degradation
- Validate data quality in model inputs or in a data pipeline
- Perform exploratory data analysis of massive datasets
- Track data distributions & data quality for ML experiments
- Enable data auditing and governance across the organization
- Standardize data documentation practices across the organization
- And more

## Python Quickstart<a name="python-quickstart" />

Installing whylogs using the pip package manager is as easy as running `pip install whylogs` in your terminal.

From here, you can quickly log a dataset:

```python
import whylogs as why
import pandas as pd

#dataframe
df = pd.read_csv("path/to/file.csv")
results = why.log(df)
```

And there you have it, you now have a whylogs profile. To learn more about what a whylogs profile is and what you can do with it, read on.
