</p>
VerticaPy is a Python library with scikit-like functionality used to conduct data science projects on data stored in Vertica, taking advantage Vertica’s speed and built-in analytics and machine learning features. VerticaPy offers robust support for the entire data science life cycle, uses a 'pipeline' mechanism to sequentialize data transformation operations, and offers beautiful graphical options.
<br><br>
Nowadays, 'Big Data' is one of the main topics in the data science world, and data scientists are often at the center of any organization. The benefits of becoming more data-driven are undeniable and are often needed to survive in the industry.
<br><br>
Vertica was the first real analytic columnar database and is still the fastest in the market. However, SQL alone isn't flexible enough to meet the needs of data scientists.
<br><br>
Python has quickly become the most popular tool in this domain, owing much of its flexibility to its high-level of abstraction and impressively large and ever-growing set of libraries. Its accessibility has led to the development of popular and perfomant APIs, like pandas and scikit-learn, and a dedicated community of data scientists. Unfortunately, Python only works in-memory as a single-node process. This problem has led to the rise of distributed programming languages, but they too, are limited as in-memory processes and, as such, will never be able to process all of your data in this era, and moving data for processing is prohobitively expensive. On top of all of this, data scientists must also find convenient ways to deploy their data and models. The whole process is time consuming.
<br><br>
**VerticaPy aims to solve all of these problems**. The idea is simple: instead of moving data around for processing, VerticaPy brings the logic to the data.
<br><br>
3 years in the making, we're proud to bring you VerticaPy.
<br><br>
Main Advantages:
<ul>
<li> Easy Data Exploration.</li>
<li> Fast Data Preparation.</li>
<li> In-Database Machine Learning.</li>
<li> Easy Model Evaluation.</li>
<li> Easy Model Deployment.</li>
</ul>

## Contributing
For a short guide on contribution standards, see <a href='https://github.com/vertica/VerticaPy/blob/master/CONTRIBUTING.md'>CONTRIBUTING.md</a>
## Connecting to the Database
VerticaPy is compatible with several clients. For details, see the <a href='https://www.vertica.com/python/connection.php'>connection page</a>.<br>
## Quickstart
The following example follows the <a href='https://www.vertica.com/python/quick-start.php'>VerticaPy quickstart guide</a>.
Install the library using with <b>pip</b>.
```shell
root@ubuntu:~$ pip3 install verticapy[all]
```
Create a new Vertica connection:
```python
import verticapy as vp
vp.new_connection({"host": "10.211.55.14",
"port": "5433",
"database": "testdb",
"password": "XxX",
"user": "dbadmin"},
name = "Vertica_New_Connection")
```
Use the newly created connection:
```python
vp.connect("Vertica_New_Connection")
```
Create a VerticaPy schema for native VerticaPy models (that is, models available in VerticaPy, but not Vertica itself):
```python
vp.create_verticapy_schema()
```
Create a vDataFrame of your relation:
```python
from verticapy import vDataFrame
vdf = vDataFrame("my_relation")
```
Load a sample dataset:
```python
from verticapy.datasets import load_titanic
vdf = load_titanic()
```
Examine your data:
```python
vdf.describe()
# Output
count mean std min
"pclass" 1234 2.28444084278768 0.842485636190292 1.0

"body" 79.25 160.5 257.5 328.0
Rows: 1-7 | Columns: 9
```
Print the SQL query with <b>set_option</b>:
```python
set_option("sql_on", True)
vdf.describe()
# Output
## Compute the descriptive statistics of all the numerical columns ##
SELECT
SUMMARIZE_NUMCOL("pclass", "survived", "age", "sibsp", "parch", "fare", "body") OVER ()
FROM public.titanic
```
With VerticaPy, it is now possible to solve a ML problem with few lines of code.
```python
from verticapy.learn.model_selection import cross_validate
from verticapy.learn.ensemble import RandomForestClassifier
# Data Preparation
vdf["sex"].label_encode()["boat"].fillna(method = "0ifnull")["name"].str_extract(' ([A-Za-z]+)\.').eval("family_size", expr = "parch + sibsp + 1").drop(columns = ["cabin", "body", "ticket", "home.dest"])["fare"].fill_outliers().fillna()
# Model Evaluation
cross_validate(RandomForestClassifier("rf_titanic", cur, max_leaf_nodes = 100, n_estimators = 30),
vdf,
["age", "family_size", "sex", "pclass", "fare", "boat"],
"survived",
cutoff = 0.35)

VerticaPy is a Python library with scikit-like functionality used to conduct data science projects on data stored in Vertica, taking advantage Vertica’s speed and built-in analytics and machine learning features. VerticaPy offers robust support for the entire data science life cycle, uses a 'pipeline' mechanism to sequentialize data transformation operations, and offers beautiful graphical options.
<br><br>
Nowadays, 'Big Data' is one of the main topics in the data science world, and data scientists are often at the center of any organization. The benefits of becoming more data-driven are undeniable and are often needed to survive in the industry.
<br><br>
Vertica was the first real analytic columnar database and is still the fastest in the market. However, SQL alone isn't flexible enough to meet the needs of data scientists.
<br><br>
Python has quickly become the most popular tool in this domain, owing much of its flexibility to its high-level of abstraction and impressively large and ever-growing set of libraries. Its accessibility has led to the development of popular and perfomant APIs, like pandas and scikit-learn, and a dedicated community of data scientists. Unfortunately, Python only works in-memory as a single-node process. This problem has led to the rise of distributed programming languages, but they too, are limited as in-memory processes and, as such, will never be able to process all of your data in this era, and moving data for processing is prohobitively expensive. On top of all of this, data scientists must also find convenient ways to deploy their data and models. The whole process is time consuming.
<br><br>
**VerticaPy aims to solve all of these problems**. The idea is simple: instead of moving data around for processing, VerticaPy brings the logic to the data.
<br><br>
3 years in the making, we're proud to bring you VerticaPy.
<br><br>
Main Advantages:
<ul>
<li> Easy Data Exploration.</li>
<li> Fast Data Preparation.</li>
<li> In-Database Machine Learning.</li>
<li> Easy Model Evaluation.</li>
<li> Easy Model Deployment.</li>

## Contributing
For a short guide on contribution standards, see <a href='https://github.com/vertica/VerticaPy/blob/master/CONTRIBUTING.md'>CONTRIBUTING.md</a>
## Connecting to the Database
VerticaPy is compatible with several clients. For details, see the <a href='https://www.vertica.com/python/connection.php'>connection page</a>.<br>
## Quickstart
The following example follows the <a href='https://www.vertica.com/python/quick-start.php'>VerticaPy quickstart guide</a>.
Install the library using with <b>pip</b>.
```shell
root@ubuntu:~$ pip3 install verticapy[all]
```
Create a new Vertica connection:
```python
import verticapy as vp
vp.new_connection({"host": "10.211.55.14",
"port": "5433",
"database": "testdb",
"password": "XxX",
"user": "dbadmin"},
name = "Vertica_New_Connection")
```
Use the newly created connection:
```python
vp.connect("Vertica_New_Connection")
```
Create a VerticaPy schema for native VerticaPy models (that is, models available in VerticaPy, but not Vertica itself):
```python
vp.create_verticapy_schema()
```
Create a vDataFrame of your relation:
```python
from verticapy import vDataFrame
vdf = vDataFrame("my_relation")
```
Load a sample dataset:
```python
from verticapy.datasets import load_titanic
vdf = load_titanic()
```
Examine your data:
```python
vdf.describe()
# Output

```
Print the SQL query with <b>set_option</b>:
```python
set_option("sql_on", True)
vdf.describe()
# Output
## Compute the descriptive statistics of all the numerical columns ##
SELECT
SUMMARIZE_NUMCOL("pclass", "survived", "age", "sibsp", "parch", "fare", "body") OVER ()
FROM public.titanic
```
With VerticaPy, it is now possible to solve a ML problem with few lines of code.
```python
from verticapy.learn.model_selection import cross_validate
from verticapy.learn.ensemble import RandomForestClassifier
# Data Preparation
vdf["sex"].label_encode()["boat"].fillna(method = "0ifnull")["name"].str_extract(' ([A-Za-z]+)\.').eval("family_size", expr = "parch + sibsp + 1").drop(columns = ["cabin", "body", "ticket", "home.dest"])["fare"].fill_outliers().fillna()
# Model Evaluation
cross_validate(RandomForestClassifier("rf_titanic", cur, max_leaf_nodes = 100, n_estimators = 30),
