- Improve and analyse performance of your neural network (e.g. Tensor Cores compatibility)
- Record/analyse internal state of
torch.nn.Moduleas data passes through it - Do the above based on external conditions (using single
Callableto specify it) - Day-to-day neural network related duties (model size, seeding, time measurements etc.)
- Get information about your host operating system,
torch.nn.Moduledevice, CUDA capabilities etc.

💡 Examples
Check documentation here: https://szymonmaszke.github.io/torchfunc
1. Getting performance tips
- Get instant performance tips about your module. All problems described by comments
will be shown by
torchfunc.performance.tips:
class Model(torch.nn.Module):
def __init__(self):
super().__init__()
self.convolution = torch.nn.Sequential(
torch.nn.Conv2d(1, 32, 3),
torch.nn.ReLU(inplace=True), # Inplace may harm kernel fusion
torch.nn.Conv2d(32, 128, 3, groups=32), # Depthwise is slower in PyTorch
torch.nn.ReLU(inplace=True), # Same as before
torch.nn.Conv2d(128, 250, 3), # Wrong output size for TensorCores
)
self.classifier = torch.nn.Sequential(
torch.nn.Linear(250, 64), # Wrong input size for TensorCores
torch.nn.ReLU(), # Fine, no info about this layer
torch.nn.Linear(64, 10), # Wrong output size for TensorCores
)
def forward(self, inputs):
convolved = torch.nn.AdaptiveAvgPool2d(1)(self.convolution(inputs)).flatten()
return self.classifier(convolved)
# All you have to do
print(torchfunc.performance.tips(Model()))
2. Seeding, weight freezing and others
- Seed globaly (including
numpyandcuda), freeze weights, check inference time and model size:
# Inb4 MNIST, you can use any module with those functions
model = torch.nn.Linear(784, 10)
torchfunc.seed(0)
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)}")
3. Record torch.nn.Module internal state
- Record and sum per-layer activation statistics as data passes through network:
# Still MNIST but any module can be put in it's place
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 all inputs to layers
recorder = torchfunc.hooks.recorders.ForwardPre(reduction=lambda x, y: x+y)
# Record only for torch.nn.Linear
recorder.children(model, types=(torch.nn.Linear,))
# Train your network normally (or pass data through it)
...
# Activations of all neurons of first layer!
print(recorder[1]) # You can also post-process this data easily with apply

🔧 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.
