A standard framework for using Deep Learning for tabular data
Project description
PyTorch Tabular aims to make Deep Learning with Tabular data easy and accessible to real-world cases and research alike. The core principles behind the design of the library are:
- Low Resistance Useability
- Easy Customization
- Scalable and Easier to Deploy
It has been built on the shoulders of giants like PyTorch(obviously), and PyTorch Lightning.

Installation
Although the installation includes PyTorch, the best and recommended way is to first install PyTorch from here, picking up the right CUDA version for your machine.
Once, you have got Pytorch installed, just use:
pip install pytorch_tabular[all]
to install the complete library with extra dependencies.
And :
pip install pytorch_tabular
for the bare essentials.
The sources for pytorch_tabular can be downloaded from the Github repo
_.
You can either clone the public repository:
git clone git://github.com/manujosephv/pytorch_tabular
Once you have a copy of the source, you can install it with:
python setup.py install

Available Models
- FeedForward Network with Category Embedding is a simple FF network, but with an Embedding layers for the categorical columns.
- Neural Oblivious Decision Ensembles for Deep Learning on Tabular Data is a model presented in ICLR 2020 and according to the authors have beaten well-tuned Gradient Boosting models on many datasets.
- TabNet: Attentive Interpretable Tabular Learning is another model coming out of Google Research which uses Sparse Attention in multiple steps of decision making to model the output.
- Mixture Density Networks is a regression model which uses gaussian components to approximate the target function and provide a probabilistic prediction out of the box.
- AutoInt: Automatic Feature Interaction Learning via Self-Attentive Neural Networks is a model which tries to learn interactions between the features in an automated way and create a better representation and then use this representation in downstream task
To implement new models, see the How to implement new models tutorial. It covers basic as well as advanced architectures.
Usage
from pytorch_tabular import TabularModel
from pytorch_tabular.models import CategoryEmbeddingModelConfig
from pytorch_tabular.config import DataConfig, OptimizerConfig, TrainerConfig, ExperimentConfig
data_config = DataConfig(
target=['target'], #target should always be a list. Multi-targets are only supported for regression. Multi-Task Classification is not implemented
continuous_cols=num_col_names,
categorical_cols=cat_col_names,
)
trainer_config = TrainerConfig(
auto_lr_find=True, # Runs the LRFinder to automatically derive a learning rate
batch_size=1024,
max_epochs=100,
gpus=1, #index of the GPU to use. 0, means CPU
)
optimizer_config = OptimizerConfig()
model_config = CategoryEmbeddingModelConfig(
task="classification",
layers="1024-512-512", # Number of nodes in each layer
activation="LeakyReLU", # Activation between each layers
learning_rate = 1e-3
)
tabular_model = TabularModel(
data_config=data_config,
model_config=model_config,
optimizer_config=optimizer_config,
trainer_config=trainer_config,
)
tabular_model.fit(train=train, validation=val)
result = tabular_model.evaluate(test)
pred_df = tabular_model.predict(test)
tabular_model.save_model("examples/basic")
loaded_model = TabularModel.load_from_checkpoint("examples/basic")
