# Alex's PyTorch Personal Trainer (ptpt)
> (name subject to change)

This repository contains my personal lightweight framework for deep learning
projects in PyTorch.

> **Disclaimer: this project is very much work-in-progress. Although technically
> useable, it is missing many features. Nonetheless, you may find some of the
> design patterns and code snippets to be useful in the meantime.**

## Installation

Install from `pip` by running `pip install ptpt`

You can also build from source. Simply run `python -m build` in the root of the
repo, then run `pip install` on the resulting `.whl` file.

## Usage
Import the library as with any other python library:
```python
from ptpt.trainer import Trainer, TrainerConfig
from ptpt.log import debug, info, warning, error, critical
```

The core of the library is the `trainer.Trainer` class. In the simplest case, 
it takes the following as input:

```python
net:            a `nn.Module` that is the model we wish to train.
loss_fn:        a function that takes a `nn.Module` and a batch as input.
                it returns the loss and optionally other metrics.
train_dataset:  the training dataset.
test_dataset:   the test dataset.
cfg:            a `TrainerConfig` instance that holds all
                hyperparameters.
```

Once this is instantiated, starting the training loop is as simple as calling
`trainer.train()` where `trainer` is an instance of `Trainer`.

`cfg` stores most of the configuration options for `Trainer`. See the class
definition of `TrainerConfig` for details on all options.

## Examples

An example workflow would go like this:

> Define your training and test datasets:

```python
transform=transforms.Compose([
    transforms.ToTensor(),
    transforms.Normalize((0.1307,), (0.3081,))
])
train_dataset = datasets.MNIST('../data', train=True, download=True, transform=transform)
test_dataset = datasets.MNIST('../data', train=False, download=True, transform=transform)
```

> Define your model:

```python
# `Net` could be any `nn.Module`
net = Net()
```

> Define your loss function that calls `net`, taking the full batch as input:

```python
# minimising classification error
def loss_fn(net, batch):
    X, y = batch
    logits = net(X)
    loss = F.nll_loss(logits, y)

    pred = logits.argmax(dim=-1, keepdim=True)
    accuracy = 100. * pred.eq(y.view_as(pred)).sum().item() / y.shape[0]
    return loss, accuracy
```

> Optionally create a configuration object:

```python
# see class definition for full list of parameters
cfg = TrainerConfig(
    exp_name = 'mnist-conv',
    batch_size = 64,
    learning_rate = 4e-4,
    nb_workers = 4,
    save_outputs = False,
    metric_names = ['accuracy']
)
```

> Initialise the Trainer class:

```python
trainer = Trainer(
    net=net,
    loss_fn=loss_fn,
    train_dataset=train_dataset,
    test_dataset=test_dataset,
    cfg=cfg
)
```

> Optionally, register some callback functions:

```python
def callback_fn(_):
    info("Congratulations, you have completed an epoch!")
trainer.register_callback(CallbackType.TrainEpoch, callback_fn)
```

> Call `trainer.train()` to begin the training loop

```python
trainer.train() # Go!
```

See more examples [here](examples/).

#### Weights and Biases Integration

Weights and Biases logging is supported via the `ptpt.wandb.WandConfig`
dataclass.

Currently only supports a small set of features:
```
class WandbConfig:
    project: str = None         # project name
    entity: str = None          # wandb entity name
    name: str = None            # run name (leave blank for random two words)
    config: dict = None         # hyperparameters to save on wandb
    log_net: bool = False       # whether to use wandb to watch network gradients
    log_metrics: bool = True    # whether to use wandb to report epoch metrics
```

If you want to log something else in addition to epoch metrics, you can use
`ptpt.callbacks` and access wandb through `trainer.wandb`. When calling log
here, ensure commit is set to `False` to avoid advancing the global step.

## Motivation
I found myself repeating a lot of same structure in many of my deep learning
projects. This project is the culmination of my efforts refining the typical
structure of my projects into (what I hope to be) a wholly reusable and 
general-purpose library.

Additionally, there are many nice theoretical and engineering tricks that
are available to deep learning researchers. Unfortunately, a lot of them are 
forgotten because they fall outside the typical workflow, despite them being
very beneficial to include. Another goal of this project is to transparently
include these tricks so they can be added and removed with minimal code change.
Where it is sane to do so, some of these could be on by default.

Finally, I am guilty of forgetting to implement decent logging: both of 
standard output and of metrics. Logging of standard output is not hard, and 
is implemented using other libraries such as [rich](https://github.com/willmcgugan/rich).
However, metric logging is less obvious. I'd like to avoid larger dependencies 
such as tensorboard being an integral part of the project, so metrics will be
logged to simple numpy arrays. The library will then provide functions to 
produce plots from these, or they can be used in another library.

### TODO:

- [X] Add arbitrary callback support at various points of execution
- [X] Add metric tracking
- [ ] Add more learning rate schedulers
- [ ] Add more optimizer options
- [ ] Add logging-to-file
- [ ] Adds silent and simpler logging
- [ ] Support for distributed / multi-GPU operations
- [ ] Set of functions for producing visualisations from disk dumps
- [ ] General suite of useful functions
