Pytorch Symbolic is MIT licensed library that adds symbolic API for model creation to PyTorch.
Pytorch Symbolic makes it easier and faster to define complex models.
It spares you writing boilerplate code.
It aims to be PyTorch equivalent for [Keras Functional API](https://keras.io/guides/functional_api/).
Features:
* Small extension of PyTorch
* No dependencies besides PyTorch
* Produces models entirely compatible with PyTorch
* Overhead free as tested in [benchmarks](https://pytorch-symbolic.readthedocs.io/en/latest/benchmarks/)
* Reduces the amount of boilerplate code
* Works well with complex architectures
* Code and documentation is automatically tested
## Example
To create a symbolic model, you need Symbolic Tensors and `torch.nn.Module`.
Register layers and operations in your model by calling ``layer(inputs)`` or
equivalently ``inputs(layer)``.
Layers will be automagically added to your model and
all operations will be replayed on the real data.
That's all!
Using Pytorch Symbolic, we can define a working classifier in a few lines of code:
```python
from torch import nn
from pytorch_symbolic import Input, SymbolicModel
inputs = Input(shape=(1, 28, 28))
x = nn.Flatten()(inputs)
x = nn.Linear(x.shape[1], 10)(x)(nn.Softmax(1))
model = SymbolicModel(inputs=inputs, outputs=x)
model.summary()
```
```stdout
_______________________________________________________
Layer Output shape Params Parent
=======================================================
1 Input_1 (None, 1, 28, 28) 0
2 Flatten_1 (None, 784) 0 1
3 Linear_1 (None, 10) 7850 2
4* Softmax_1 (None, 10) 0 3
=======================================================
Total params: 7850
Trainable params: 7850
Non-trainable params: 0

## Gentle introduction
There's a jupyter notebook showing the basic usage of Pytorch Symbolic. With it you will:
* Learn Pytorch Symbolic in an interactive way
* Try the package before installing it on your computer
* See visualizations of graphs that are created under the hood
