skt 1.0.10
SKT package
Requires Python: >=3.10

# SKT Package

[![Actions Status](https://github.com/sktaiflow/skt/workflows/release/badge.svg)](https://github.com/sktaiflow/skt/actions)

This is highly site dependent package.
Resources are abstracted into package structure.

## Usage

Hive metastore

```python
from skt.ye import get_hms

c = get_hms()
c.get_partition_names("db", "table")
c.close()
```

Hash and unhash

```python
from skt.lake import hash_s
from skt.lake import unhash_s

unhashed_list = ['0000000000']
hashed_list = hash_s(unhashed_list)
unhash_s(hashed_list)
```

Get pandas dataframe from parquet file in hdfs

```python
from skt.ye import parquet_to_pandas

pandas_df = parquet_to_pandas(hdfs_path)
```

Save pandas dataframe as parquet in hdfs

```python
from skt.ye import get_spark
from skt.ye import pandas_to_parquet

spark = get_spark()
pandas_to_parquet(pandas_df, hdfs_path, spark)  # we need spark for this operation
spark.stop()
```

Work with spark

```python
from skt.ye import get_spark

spark = get_spark()
# do with spark session
spark.stop()
```

Work with spark-bigquery-connector

```python
# SELECT
from skt.gcp import bq_table_to_pandas

pandas_df = bq_table_to_pandas("dataset", "table_name", ["col_1", "col_2"], "2020-01-01", "svc_mgmt_num is not null")
# INSERT 
from skt.gcp import pandas_to_bq_table

pandas_to_bq_table(pandas_df, "dataset", "table_name", "2020-03-01")
```

Send slack message

```python
from skt.ye import slack_send

text = 'Hello'
username = 'airflow'
channel = '#leavemealone'
slack_send(text=text, username=username, channel=channel)
# Send dataframe as text
df = pd.DataFrame(data={'col1': [1, 2], 'col2': [3, 4]})
slack_send(text=df, username=username, channel=channel, dataframe=True)
```

Get bigquery client

```python
from skt.gcp import get_bigquery_client

bq = get_bigquery_client()
bq.query(query)
```

IPython BigQuery Magic

```python
from skt.gcp import import_bigquery_ipython_magic

import_bigquery_ipython_magic()

query_params = {
    "p_1": "v_1",
    "dataset": "mnoai",
}
```

```python
%% bq --params $query_params

SELECT c_1 
FROM {dataset}.user_logs
WHERE c_1 = @p_1
```

Use NES CLI

```bas
nes input_notebook_url -p k1 v1 -p k2 v2 -p k3 v3
```

Use github util

```python
from skt.ye import get_github_util

g = get_github_util
# query graphql
res = g.query_gql(graph_ql)
# get file in github repository
byte_object = g.download_from_git(github_url_path)
```

## Installation

```sh
$ pip install skt --upgrade
```

If you would like to install submodules for AIR

```sh
$ pip install skt[air] --upgrade
```

# AIPS EDA tools

## OVERVIEW

- **Modeling EDA** 시 활용할 수 있는 기능의 공통 module
- **Modules**
  -
        1) EDA (Nuemric / Categorical variable)
           <br>
           <br>

## 1) EDA

#### 1. Numeric variable EDA

- **def** *numeric_eda_plot*

```
    Numeric feature에 대한 EDA Plot function
    
    Args. :
        - df           :   Pandas DataFrame 형태의 EDA대상 데이터
        - feature_list :   EDA 대상 feature list (df의 columns)
        - label_col    :   Label(or Hue) column
        - cols         :   Multi-plot 시 grid column 개수 (row 개수는 feature_list에 따라 자동으로 결정 됨)
        - n_samples    :   Label 별 sampling 할 개수 (default = -1(전수 데이터로 EDA할 경우))
        - plot_type    :   density or box (default = 'density')
        - stat_yn      :   기초 통계량 출력여부 (mean / min / max / 1q / 3q) (default : False)
        - figsize      :   (default : (7,4))
    
    Returns : 
        matplotlib.pyplot object

    Example : 
        fig = numeric_eda_plot(df, ['age'], 'answer', cols = 1, n_samples = 10000, plot_type='density', stat_yn=True, figsize = (7,4))
        fig
        
        if want to Save the EDA images,
        fig.savefig('filename')
```

#### 2. Categorical variable EDA

- **def** *categorical_eda_plot*

```
    Categorical feature에 대한 EDA Plot function
    
    Args. :
        - df           :   Pandas DataFrame 형태의 EDA대상 데이터
        - feature_list :   EDA 대상 feature list (df의 columns)
        - label_col    :   Label(or Hue) column
        - cols         :   Multi-plot 시 grid column 개수 (row 개수는 feature_list에 따라 자동으로 결정 됨)
        - n_samples    :   Label 별 sampling 할 개수 (default = -1(전수 데이터로 EDA할 경우))
        - figsize      :   (default : (7,4))
    
    Returns : 
        matplotlib.pyplot object


    Example : 
        Example : 
        fig = categorical_eda_plot(df, ['sex_cd'], 'answer', cols = 1, n_samples = 10000, figsize = (7,4))
        fig
        
        if want to Save the EDA images,
        fig.savefig('filename')
    
```
