# TraceML

Engine for ML/Data tracking, visualization, explainability, drift detection, and dashboards for Polyaxon.

## Install

```bash
pip install traceml
```

If you would like to use the tracking features, you need to install `polyaxon` as well:

```bash
pip install polyaxon traceml
```

## [WIP] Local sandbox

> Coming soon

## Offline usage

You can enable the offline mode to track runs without an  API:

```bash
export POLYAXON_OFFLINE="true"
```

Or passing the offline flag

```python
from traceml import tracking

tracking.init(..., is_offline=True, ...)
```

## Simple usage in a Python script

```python
import random

import traceml as tracking

tracking.init(
    is_offline=True,
    project='quick-start',
    name="my-new-run",
    description="trying TraceML",
    tags=["examples"],
    artifacts_path="path/to/artifacts/repo"
)

# Tracking some data refs
tracking.log_data_ref(content=X_train, name='x_train')
tracking.log_data_ref(content=y_train, name='y_train')

# Tracking inputs
tracking.log_inputs(
    batch_size=64,
    dropout=0.2,
    learning_rate=0.001,
    optimizer="Adam"
)

def get_loss(step):
    result = 10 / (step + 1)
    noise = (random.random() - 0.5) * 0.5 * result
    return result + noise

# Track metrics
for step in range(100):
    loss = get_loss(step)
    tracking.log_metrics(
    loss=loss,
    accuracy=(100 - loss) / 100.0,
)

# Track some one time results
tracking.log_outputs(validation_score=0.66)

# Optionally manually stop the tracking process
tracking.stop()
```

## Integration with deep learning and machine learning libraries and frameworks

### Keras

You can use TraceML's callback to automatically save all metrics and collect outputs and models, you can also track additional information using the logging methods:

```python
from traceml import tracking
from traceml.integrations.keras import Callback

tracking.init(
    is_offline=True,
    project='tracking-project',
    name="keras-run",
    description="trying TraceML & Keras",
    tags=["examples"],
    artifacts_path="path/to/artifacts/repo"
)

tracking.log_inputs(
    batch_size=64,
    dropout=0.2,
    learning_rate=0.001,
    optimizer="Adam"
)
tracking.log_data_ref(content=x_train, name='x_train')
tracking.log_data_ref(content=y_train, name='y_train')
tracking.log_data_ref(content=x_test, name='x_test')
tracking.log_data_ref(content=y_test, name='y_test')

# ...

model.fit(
    x_train,
    y_train,
    validation_data=(X_test, y_test),
    epochs=epochs,
    batch_size=100,
    callbacks=[Callback()],
)
```

### PyTorch

You can log metrics, inputs, and outputs of Pytorch experiments using the tracking module:

```python
from traceml import tracking

tracking.init(
    is_offline=True,
    project='tracking-project',
    name="pytorch-run",
    description="trying TraceML & PyTorch",
    tags=["examples"],
    artifacts_path="path/to/artifacts/repo"
)

tracking.log_inputs(
    batch_size=64,
    dropout=0.2,
    learning_rate=0.001,
    optimizer="Adam"
)

# Metrics
for batch_idx, (data, target) in enumerate(train_loader):
    output = model(data)
    loss = F.nll_loss(output, target)
    loss.backward()
    optimizer.step()
    tracking.log_metrics(loss=loss)

asset_path = tracking.get_outputs_path('model.ckpt')
torch.save(model.state_dict(), asset_path)

# log model
tracking.log_artifact_ref(asset_path, framework="pytorch", ...)
```

### Tensorflow

You can log metrics, outputs, and models of Tensorflow experiments and distributed Tensorflow experiments using the tracking module:

```python
from traceml import tracking
from traceml.integrations.tensorflow import Callback

tracking.init(
    is_offline=True,
    project='tracking-project',
    name="tf-run",
    description="trying TraceML & Tensorflow",
    tags=["examples"],
    artifacts_path="path/to/artifacts/repo"
)

tracking.log_inputs(
    batch_size=64,
    dropout=0.2,
    learning_rate=0.001,
    optimizer="Adam"
)

# log model
estimator.train(hooks=[Callback(log_image=True, log_histo=True, log_tensor=True)])
```

### Fastai

    is_offline=True,
    project='tracking-project',
    name="fastai-run",
    description="trying TraceML & Fastai",
    tags=["examples"],
    artifacts_path="path/to/artifacts/repo"
)

# Log model metrics
learn.fit(..., cbs=[Callback()])
```

## Tracking DataFrames

### Summary

An extension to [pandas](http://pandas.pydata.org/) dataframes describe function.

The module contains `DataFrameSummary` object that extend `describe()` with:

- **properties**
  - dfs.columns_stats: counts, uniques, missing, missing_perc, and type per column
  - dsf.columns_types: a count of the types of columns
  - dfs[column]: more in depth summary of the column
- **function**
  - summary(): extends the `describe()` function with the values with `columns_stats`

The `DataFrameSummary` expect a pandas `DataFrame` to summarise.

```python
from traceml.summary.df import DataFrameSummary

dfs = DataFrameSummary(df)
```

getting the columns types

```python
dfs.columns_types

numeric     9
bool        3
categorical 2
unique      1
date        1
constant    1
dtype: int64
```

getting the columns stats

```python
dfs.columns_stats

A            B        C              D              E
counts             5802         5794     5781           5781           4617
uniques            5802            3     5771            128            121
missing               0            8       21             21           1185
missing_perc         0%        0.14%    0.36%          0.36%         20.42%
types            unique  categorical  numeric        numeric        numeric
```

getting a single column summary, e.g. numerical column

```python
# we can also access the column using numbers A[1]
dfs['A']
