## Installation
Use the package manager [pip](https://pypi.org/project/pymlpipe/) to install PyMLpipe.
```bash
pip install pymlpipe
```
or
```bash
pip3 install pymlpipe
```
## Frame Work Supports
- [X] Scikit-Learn
- [X] XGBoost
- [X] LightGBM
- [X] Pytorch
- [ ] Tensorflow
- [ ] Keras
## Tutorial (Scikit-Learn|XGBoost|LightGBM)
* Load the python package
```python
from pymlpipe.tabular import PyMLPipe
```
* Initiate the `PyMLPipe` class
```python
mlp=PyMLPipe()
```
* Set an Experiment Name `[Optional]`-Default experiment name is `'0'`
```python
mlp.set_experiment("IrisDataV2")
```
* Set a version `[Optional]`-Default there is no version
```python
mlp.set_version(0.1)
```
* Initiate the context manager - This is create a unique ID for each model run.
- when `.run()` is used - Automatic unique ID is generated
- you can also provide `runid` argument in the `.run()` this will the use the given `runid` for next storing.
```python
with mlp.run():
```
Or
```python
with mlp.run(runid='mlopstest'):
```
* Set a Tag `[Optional]` by using `set_tag()`-Default there is no tags
```python
mlp.set_tag('tag')
```
Or
* Set multiple Tags `[Optional]` by using `set_tags()`-Default there is no tags
```python
mlp.set_tags(["Classification","test run","logisticRegression"])
```
* Set Metrics values `[Optional]` by using `log_matric(metric_name,metric_value)`-Default there is no metrics
This will help in comparing performance of different models and model versions
```python
mlp.log_metric("Accuracy", accuracy_score(testy,predictions))
mlp.log_metric("Accuracy", .92)
```
* Set multiple Metrics values `[Optional]` by using `log_matrics({metric_name:metric_value})`-Default there is no metrics
```python
mlp.log_metrics(
{
"Accuracy": accuracy_score(testy,predictions),
"Precision": precision_score(testy,predictions,average='macro'),
"Recall": recall_score(testy,predictions,average='macro'),
}
)
mlp.log_metrics({
"Accuracy": .92,
"Precision": .87,
"Recall": .98,
}
)
```
* Save an artifact `[Optional]` - You can save training/testing/validation/dev/prod data for monitoring and comparison
- This will also help in generating `DATA SCHEMA`
- `register_artifact()` -takes 3 arguments
- name of artifact
- Pandas Dataframe
- type of artifact - `[training, testing, validation, dev, prod]`
- You can also use `register_artifact_with_path()` - This will save the artifact from the disk.
- Path for the file
- type of artifact - `[training, testing, validation, dev, prod]`
```python
mlp.register_artifact("train.csv", trainx)
mlp.register_artifact("train.csv", trainx)
```
* Register Model `[Optional]` - You can register the model. This will help in Quick deployment
```python
mlp.scikit_learn.register_model("logistic regression", model)
```
#### XAI
To get model explaination , feature importance we can use `explainer()`
explainer takes two objects
- model - the model used for training
- trainx - the training data
```python
mlp.explainer(model,trainx)
```
## Quick Start (Scikit-Learn|XGBoost|LightGBM)
```python
from sklearn.datasets import load_iris
import pandas as pd
from sklearn.model_selection import train_test_split
from sklearn.linear_model import LogisticRegression
from sklearn.metrics import accuracy_score,precision_score,recall_score,f1_score
#import PyMLPipe from tabular
from pymlpipe.tabular import PyMLPipe
# Initiate the class
mlp=PyMLPipe()
# Set experiment name
mlp.set_experiment("IrisDataV2")
# Set Version name
mlp.set_version(0.2)
iris_data=load_iris()
data=iris_data["data"]
target=iris_data["target"]
df=pd.DataFrame(data,columns=iris_data["feature_names"])
trainx,testx,trainy,testy=train_test_split(df,target)
# to start monitering use mlp.run()
with mlp.run():
# set tags
mlp.set_tags(["Classification","test run","logisticRegression"])
model=LogisticRegression()
model.fit(trainx, trainy)
predictions=model.predict(testx)
# log performace metrics
mlp.log_metric("Accuracy", accuracy_score(testy,predictions))
mlp.log_metric("Precision", precision_score(testy,predictions,average='macro'))
mlp.log_metric("Recall", recall_score(testy,predictions,average='macro'))
mlp.log_metric("F1", f1_score(testy,predictions,average='macro'))
# Save train data and test data
mlp.register_artifact("train", trainx)
mlp.register_artifact("test", testx,artifact_type="testing")
# Save the model
mlp.scikit_learn.register_model("logistic regression", model)
# Model explainer
mlp.explainer(model,trainx)
```
## Launch UI
To start the UI
```bash
pymlpipeui
```
or
```python
from pymlpipe.pymlpipeUI import start_ui
start_ui(host='0.0.0.0', port=8085)
```
#### Sample UI
---
---
XAI
---
#### One Click Deployment -click the deploy button to deploy the model and get a endpoint
---
---
## Send the data to the Prediction end point in the format
- Each list is a row of data
```python
{
"data":[
[5.6,3.0,4.5,1.5],
[5.6,3.0,4.5,1.5]
]
}
```
---
## Tutorial (Pytorch)
#### The previous methods can be used as it is. New methods are shown below
* Log continious Metrics `.log_metrics_continious(dict)--> dict of metrics`\
- logs the metrics in a continious manner for each epoch
```pytorch
mlp.log_metrics_continious({
"accuracy": .9,
"precision": .8,
"recall": .7
})
```
* To register a pytorch model use `.pytorch.register_model(modelname, modelobject)`
- this will Save the model in a .pt file as a `torch.jit` format for serveing and prediction
```python
mlp.pytorch.register_model("pytorch_example1", model)
```
* To register a pytorch model use `.pytorch.register_model_with_runtime(modelname, modelobject, train_data_sample)`
- `train_data_sample`- is a sample of input data. it can be random numbers but needs tensor dimension
- This method is `preferred` as in `future releases` this models can be then converted to other formats as well ex: "onnx", "hd5"
```python
mlp.pytorch.register_model_with_runtime("pytorch_example1", model, train_x)
```

### Sample input for prediction
`GET REQUEST` - to get info for the model
- `info` : Contains model information
- `request_body`: Sample post Request
```python
{
"info": {
"experiment_id": "Pytorch",
"model_deployment_number": "51c186ddd125386c",
"model_mode": "non_runtime",
"model_type": "torch",
"model_url": "/predict/51c186ddd125386c",
"run_id": "3fffe458-9676-4bc7-a6c0-a3b4cf38e277",
"status": "running"
},
"request_body": {
"data": [
[
42.0,120.0,1.0,0.0,0.0,0.0,185.7,133.0,31.57,235.1,149.0,19.98,
256.4,78.0,11.54,16.9,6.0,4.56,0.0
]
],
"dtype": "float"
}
}
```
For `POST REQUEST`
-`data`--> list: contains data rows for prediction supports both batch prediction and single instance ex: data --> [ [ 0,1,2,3],[3,4,56 ] ]
-`dtype`--> str: for type conversion converts the data into required data type tensor
```
{
"data": [
[
42.0,120.0,1.0,0.0,0.0,0.0,185.7,133.0,31.57,235.1,149.0,19.98,
256.4,78.0,11.54,16.9,6.0,4.56,0.0
]
],
"dtype": "float"
}
```
## Quick Start (AutoML)
```python
from automl import AutoMLPipe
from sklearn.datasets import load_iris,load_diabetes
import pandas as pd
import numpy as np
def main():
load_data=load_diabetes()
data=load_data["data"]
target=load_data["target"]
df=pd.DataFrame(data,columns=load_data["feature_names"])
automl_obj=AutoMLPipe(
exp_name="DiabAutoMLV1",
task="regression",
metric="RMSE",
data=df,
label=target,
tags=["new_data","reg"],
test_size=0.2,
version=1.0,
transform=True,
scale='normalize',
cols_to_scale=[],
categorical_cols=[],
register_model=True,
explain=True,exclude=[]
)
preds,result=automl_obj.run_automl(tune=True,tune_best=False)
#DataFrame with comparative metrics of all the models
print(result)
#Dictionary with model names and the predictions
print(preds)
if __name__ == '__main__':
main()
```
The AutoML class is simple to run and with the help of few lines of code you'll be able to run several models on your data. You can even choose to hyperparameter tune every model or you can just tune the best model based on the metric that you provide. Below are the simple steps to start your AutoML experiment.
- Load the data
- Transform it into X & y datasets.
- Instanciate the AutoMLPipe class:
- `exp_name`: name of experiment
- `task`: regression/classification
- `metric`: for classification -> accuracy,recall,precision,f1/ for regression -> MAE,MSE,RMSE,R2 Score
- `data`: data on which the model to be fit
- `label`: target variable
- `tags`: list of custom-tags for the run
- `test_size`: size of test dataset
- `version`: experiment version
- `transform`: If transformation is to be applied on the dataset.
- `scale`: 'standard'/'minmax'/'normalize'
- `cols_to_scale`: list of columns to scale. Should be numeric or float
- `categorical_cols`: columns to one-hot encode
- `register_model`: register experiement model
- `register_artifacts`: register experiment artifacts
- `explain`: xai implementation
- `exclude`: models to be excluded during autoML runs
- run the experiment by calling the `run_automl` function.
- `tune=True`: Every autoML models will be hyperparameter tuned.
- `tune_best=True`: Only the best model will be hyperparameter tuned.
- Now you can see the experiment running in the ui page and also in the console.
- Once it is completed you will get results and predictions of the runs.
- If `tune_best=False`: The `result` will have the dataframe with metrics of each model. The `pred` will contain the dictionary of all the prediction values of all the models.
- If `tune_best=True`: The `result` will have the dataframe with metrics of each model. The `pred` will contain the a list of prediction values of the hyperparameter tuned best model.
## Quick Start (Data Pipeline)
This is a sample code for data pipeline.
**Please don't take the code too seriously**
```python
#filename : sample.py
from pymlpipe import pipeline
pl=pipeline.PipeLine("TestCase")
# Just some random functions
def fetch_data():
dict_data={
"var":"this is a random string:",
"path":"this is some random path"
}
return dict_data
def get_dict_values(data_dict):
new_var=[v for k,v in data_dict.items()]
return new_var
def get_dict_keys(data_dict):
new_var=[k for k,v in data_dict.items()]
return new_var
def a_edge_node(values):
print(values)
def dump_data(keys,values):
dict_data_rev={k:v for k,v in zip(keys,values)}
print(dict_data_rev)
pl.add_node("fetch_data",fetch_data,entry_node=True)
pl.add_node("get_dict_values",get_dict_values,input_nodes=["fetch_data"])
pl.add_node("get_dict_keys",get_dict_keys,input_nodes=["fetch_data"])
pl.add_node("a_edge_node",a_edge_node,input_nodes=["get_dict_values"])
pl.add_node("dump_data",dump_data,input_nodes=["get_dict_keys","get_dict_values"])
pl.register_dag()
```
To define a pipeline Object we can use:
We are nameing the pipeline `TestCase`
```python
from pymlpipe import pipeline
pl=pipeline.PipeLine("TestCase")
```
The `add_node` function takes
```
node_name (str): Name of the node
function (_type_): Python function you want to execute
input_nodes (list, optional): List of nodes that are connected to this node. The connected nodes should return a value which will act as an input to the node . Defaults to None.
entry_node (bool, optional): boolean flag indicating if this is the starting node(first node). Defaults to False.
args (list, optional): Run time arguments . Defaults to None.
```
```python
pl.add_node("fetch_data",fetch_data,entry_node=True)
```
The `register_dag` function creates a Dag
```python
pl.register_dag()
```
StepRun : Once done you can run the file using `python3 sample.py`
To test the Code you can run
```python
from pymlpipe import pipeline
ppl=pipeline.PipeLine("TestCase")
ppl.load_pipeline()
ppl.run()
```
The `load_pipeline` will load the pipeline dag saved after *StepRun*
The `run` function will run the given pipeline.
```python
ppl.run()
```
or you can go to web browser by running the command
```bash
~ pymlpipeui
```
Or starting the UI with
```python
from pymlpipe.pymlpipeUI import start_ui
start_ui(host='0.0.0.0', port=8085,debug=True)
```
This is a sample control page for the pipeline
Sample Dag
Node in GREEN.--> Completed Node
Node in RED. --> Failed Node
# Integrate with Model monitering
```python
from pymlpipe import pipeline
import pandas as pd
from sklearn.datasets import load_iris
import pandas as pd
from sklearn.model_selection import train_test_split
from pymlpipe.tabular import PyMLPipe
from sklearn.linear_model import LogisticRegression
from sklearn.ensemble import RandomForestClassifier
from sklearn.tree import DecisionTreeClassifier
from xgboost import XGBClassifier
from sklearn.metrics import accuracy_score,precision_score,recall_score,f1_score
import time
ppl=pipeline.PipeLine("IrisData")
mlp=PyMLPipe()
mlp.set_experiment("pipelinecheck")
mlp.set_version(0.1)
def get_data():
iris_data=load_iris()
data=iris_data["data"]
target=iris_data["target"]
df=pd.DataFrame(data,columns=iris_data["feature_names"])
trainx,testx,trainy,testy=train_test_split(df,target)
return {"trainx":trainx,"trainy":trainy,"testx":testx,"testy":testy}
def get_model(model):
if model==0:
return LogisticRegression()
elif model==1:
return RandomForestClassifier()
def train_model(data,model_name):
with mlp.run():
trainx,trainy=data["trainx"],data["trainy"]
mlp.set_tags(["Classification","test run","logisticRegression"])
model=get_model(model_name)
model.fit(trainx, trainy)
mlp.scikit_learn.register_model(str(model_name), model)
return model
def evaluate(data,model):
testx,testy=data["testx"],data["testy"]
print(model.predict(testx))
ppl.add_node("data", get_data,entry_node=True)
for idx,model in enumerate([0,1]):
ppl.add_node(
f"model_train{str(idx)}",
train_model,
input_nodes=["data"],
args={"model_name":model},
)
ppl.add_node(
f"eval_train{str(idx)}",
evaluate,
input_nodes=["data", f"model_train{str(idx)}"],
)
ppl.register_dag()
```
You can integrate the pipeline with model monitering using the same format as we did for `pymlpipe.tabular`
```python
mlp=PyMLPipe()
mlp.set_experiment("pipelinecheck")
mlp.set_version(0.1)
.
.
.
with mlp.run():
trainx,trainy=data["trainx"],data["trainy"]
mlp.set_tags(["Classification","test run","logisticRegression"])
model=get_model(model_name)
model.fit(trainx, trainy)
mlp.scikit_learn.register_model(str(model_name), model)
```
