TNT is a library providing powerful dataloading, logging and visualization utilities for Python. It is closely integrated with PyTorch and is designed to enable rapid iteration with any model or training regimen.
Make sure you have PyTorch installed, then do:
pip install git+https://github.com/pytorch/tnt.git@master
To update:
pip install --upgrade git+https://github.com/pytorch/tnt.git@master
TNT (imported as torchnet) is a framework for PyTorch which provides a set of abstractions for PyTorch aiming at encouraging code re-use as well as encouraging modular programming. It provides powerful dataloading, logging, and visualization utilities.
The project was inspired by TorchNet, and legend says that it stood for “TorchNetTwo”. Since the deprecation of TorchNet TNT has developed on its own.
For example, TNT provides simple methods to record model preformance in the torchnet.meter module and to log them to Visdom
(or in the future, TensorboardX) with the torchnet.logging module.
In the future, TNT will also provide strong support for multi-task learning and transfer learning applications. It currently supports joint training data loading through torchnet.utils.MultiTaskDataLoader.
Most of the modules support NumPy arrays as well as PyTorch tensors on input, and so could potentially be used with other frameworks.
See some of the examples in https://github.com/pytorch/examples. We would like to include some walkthroughs in the docs (contributions welcome!).
What's been ported so far:
- Datasets:
- BatchDataset
- ListDataset
- ResampleDataset
- ShuffleDataset
- TensorDataset [new]
- TransformDataset
- Meters:
- APMeter
- mAPMeter
- AverageValueMeter
- AUCMeter
- ClassErrorMeter
- ConfusionMeter
- MovingAverageValueMeter
- MSEMeter
- TimeMeter
- Engines:
- Engine
- Logger
- Logger
- VisdomLogger
- MeterLogger [new, easy to plot multi-meter via Visdom]
Any dataset can now be plugged into torch.utils.DataLoader, or called
.parallel(num_workers=8) to utilize multiprocessing.
