The package requires python >= 3.7. To install the package, type the following command:

pip install .

Example Usage

In our framework, we use AutoGNN to easily create graph neural networks for zero-shot learning.

from zsl_kg.class_encoder.auto_gnn import AutoGNN
from zsl_kg.common.graph import NeighSampler

trgcn = {
    "input_dim": 300,
    "output_dim": 2049,
    "type": "trgcn",
    "gnn": [
            "input_dim": 300,
            "output_dim": 2048,
            "activation": nn.LeakyReLU(0.2),
            "normalize": True,
            "sampler": NeighSampler(100, mode="topk"),
            "fh": 100,
            "input_dim": 2048,
            "output_dim": 2049,
            "activation": None,
            "normalize": True,
            "sampler": NeighSampler(50, mode="topk"),

class_encoder = AutoGNN(trgcn)

Our framework supports the following graph neural networks: gcn, gat, rgcn, lstm, trgcn. You can change the type to any of the available to graph neural networks to instantly create a new graph neural network.
