The data object will be transformed before being saved to disk. (default: :obj:`None`) pre_filter (callable, optional): A function that takes in an :obj:`torch_geometric.data.Data` object and returns a boolean value, indicating whether the data object should be included in the final dataset. (default: :obj:`None`) Stats: .. list-table:: :widths ...
For creating datasets which do not fit into memory, the torch_geometric.data.Dataset can be used, which closely follows the concepts of the torchvision datasets. It expects the following methods to be implemented in addition: torch_geometric.data.Dataset.len(): Returns the number of examples in your dataset.
A dataset of county level chicken pox cases in Hungary between 2004 and 2014. We made it public during the development of PyTorch Geometric Temporal. The underlying graph is static - vertices are counties and edges are neighbourhoods. Vertex features are lagged weekly counts of the chickenpox cases (we included 4 lags).
PyG Documentation¶. PyG (PyTorch Geometric) is a library built upon PyTorch to easily write and train Graph Neural Networks (GNNs) for a wide range of applications related to structured data.. It consists of various methods for deep learning on graphs and other irregular structures, also known as geometric deep learning, from a variety of published papers.
Args: root (string, optional): Root directory where the dataset should be saved. (optional: :obj:`None`) transform (callable, optional): A function/transform that takes in an:obj:`torch_geometric.data.Data` object and returns a transformed version. The data object will be transformed before every access.
Note. Some datasets may not come with any node labels. You can then either make use of the argument use_node_attr to load additional continuous node attributes (if present) or provide synthetic node features using transforms such as like torch_geometric.transforms.Constant or torch_geometric.transforms.OneHotDegree.

torch_geometric.data¶ ... A data object describing a homogeneous graph. The data object can hold node-level, link-level and graph-level attributes. In general, ...
Implementing datasets by yourself is straightforward and you may want to take a look at the source code to find out how the various datasets are implemented.
The data object will be transformed before being saved to disk. (default: :obj:`None`) pre_filter (callable, optional): A function that takes in an :obj:`torch_geometric.data.Data` object and returns a boolean value, indicating whether the data object should be included in the final dataset. (default: :obj:`None`) """ @property def raw_file ...
Creating “In Memory Datasets”¶ In order to create a torch_geometric.data.InMemoryDataset, you need to implement four fundamental methods:. torch_geometric.data.InMemoryDataset.raw_file_names(): A list of files in the raw_dir which needs to be found in order to skip the download.
At its core, PyG provides the following main features: Data Handling of Graphs. Common Benchmark Datasets. Mini-batches. Data Transforms. Learning Methods ...
