torchfunc is library revolving around PyTorch with a goal to help you with:

• Improving and analysing performance of your neural network
• Daily neural network duties (model size, seeding, performance measurements etc.)
• Plotting and visualizing modules
• Record neuron activity and tailor it to your specific task or target
• Get information about your host operating system, CUDA devices and others

Quick examples

• Seed globaly, Freeze weights, check inference time and model size

# Inb4 MNIST, you can use any module with those functions
model = torch.nn.Linear(784, 10)
frozen = torchfunc.module.freeze(model, bias=False)

with torchfunc.Timer() as timer:
  frozen(torch.randn(32, 784)
  print(timer.checkpoint()) # Time since the beginning
  frozen(torch.randn(128, 784)
  print(timer.checkpoint()) # Since last checkpoint

print(f"Overall time {timer}; Model size: {torchfunc.sizeof(frozen)}")

• Recorder and sum per-layer activation statistics as data passes through network:

# MNIST classifier
model = torch.nn.Sequential(
    torch.nn.Linear(784, 100),
    torch.nn.ReLU(),
    torch.nn.Linear(100, 50),
    torch.nn.ReLU(),
    torch.nn.Linear(50, 10),
)
# Recorder which sums layer inputs from consecutive forward calls
recorder = torchfunc.record.ForwardPreRecorder(reduction=lambda x, y: x+y)
# Record inputs going into Linear(100, 50) and Linear(50, 10)
recorder.children(model, indices=(2, 3))
# Train your network normally (or pass data through it)
...
# Save tensors (of shape 100 and 50) in folder, each named 1.pt and 2.pt respectively
recorder.save(pathlib.Path("./analysis"))

For performance tips, plotting and other check torchfunc documentation.

Installation

pip

Latest release:

pip install --user torchfunc

Nightly:

pip install --user torchfunc-nightly

Docker

CPU standalone and various versions of GPU enabled images are available at dockerhub.

For CPU quickstart, issue:

docker pull szymonmaszke/torchfunc:18.04

Nightly builds are also available, just prefix tag with nightly_. If you are going for GPU image make sure you have nvidia/docker installed and it's runtime set.
