Documentation

TorchArc CI

Build PyTorch networks by specifying architectures.

Installation

pip install torcharc

Bring your own PyTorch: this allows you to use the version of PyTorch as needed - GPU/CPU, nightly etc. For example:

conda install pytorch -c pytorch

Usage

Given just the architecture, torcharc can build generic DAG (directed acyclic graph) of nn modules, which consists of:

  • single-input-output modules: Conv1d, Conv2d, Conv3d, Linear, Perceiver or any other valid nn.Module
  • fork modules: ReuseFork, SplitFork
  • merge modules: ConcatMerge, FiLMMerge

The custom modules are defined in torcharc/module, registered in torcharc/module_builder.py.

The full examples of architecture references are in torcharc/arc_ref.py, and full functional examples are in test/module/. Below we walk through some main examples.

ConvNet

DAG: Hydra

Ultimately, we can build a generic DAG network using the modules linked by the fork and merge modules. The example below shows HydraNet - a network with multiple inputs and multiple outputs.

arc = {
    'dag_in_shape': {'image': [3, 20, 20], 'vector': [8]},
    'image': {
        'type': 'Conv2d',
        'in_names': ['image'],
        'layers': [
            [16, 4, 2, 0, 1],
            [16, 4, 1, 0, 1]
        ],
        'batch_norm': True,
        'activation': 'ReLU',
        'dropout': 0.2,
        'init': 'kaiming_uniform_',
    },
    'merge': {
        'type': 'FiLMMerge',
        'in_names': ['image', 'vector'],
        'names': {'feature': 'image', 'conditioner': 'vector'},
    },
    'Flatten': {
        'type': 'Flatten'
    },
    'Linear': {
        'type': 'Linear',
        'layers': [64, 32],
        'batch_norm': True,
        'activation': 'ReLU',
        'dropout': 0.2,
        'init': 'kaiming_uniform_',
    },
    'out': {
        'type': 'Linear',
        'out_features': 8,
    },
    'fork': {
        'type': 'SplitFork',
        'shapes': {'mean': [4], 'std': [4]},
    }
}
model = torcharc.build(arc)

batch_size = 16
dag_in_shape = arc['dag_in_shape']
xs = {'image': torch.rand([batch_size, *dag_in_shape['image']]), 'vector': torch.rand([batch_size, *dag_in_shape['vector']])}
# returns dict if output is multi-model, Tensor otherwise
ys = model(xs)
model 

DAGNet(
  (module_dict): ModuleDict(
    (image): Sequential(
      (0): Conv2d(3, 16, kernel_size=(4, 4), stride=(2, 2))
      (1): BatchNorm2d(16, eps=1e-05, momentum=0.1, affine=True, track_running_stats=True)
      (2): ReLU()
      (3): Dropout2d(p=0.2, inplace=False)
      (4): Conv2d(16, 16, kernel_size=(4, 4), stride=(1, 1))
      (5): BatchNorm2d(16, eps=1e-05, momentum=0.1, affine=True, track_running_stats=True)
      (6): ReLU()
      (7): Dropout2d(p=0.2, inplace=False)
    )
    (merge): FiLMMerge(
      (conditioner_scale): Linear(in_features=8, out_features=16, bias=True)
      (conditioner_shift): Linear(in_features=8, out_features=16, bias=True)
    )
    (Flatten): Flatten()
    (Linear): Sequential(
      (0): Linear(in_features=576, out_features=64, bias=True)
      (1): BatchNorm1d(64, eps=1e-05, momentum=0.1, affine=True, track_running_stats=True)
      (2): ReLU()
      (3): Dropout(p=0.2, inplace=False)
      (4): Linear(in_features=64, out_features=32, bias=True)
      (5): BatchNorm1d(32, eps=1e-05, momentum=0.1, affine=True, track_running_stats=True)
      (6): ReLU()
      (7): Dropout(p=0.2, inplace=False)
    )
    (out): Linear(in_features=32, out_features=8, bias=True)
    (fork): SplitFork()
  )
)

DAG module accepts a dict (example below) as input, and the module selects its input by matching its own name in the arc and the in_name, then carry forward the output together with any unconsumed inputs.

For example, the input xs with keys image, vector passes through the first image module, and the output becomes {'image': image_module(xs.image), 'vector': xs.vector}. This is then passed through the remainder of the modules in the arc as declared.
