gamengen-pytorch

GameNGen - Pytorch (wip)

Implementation of a framework for Gamengen in Pytorch

Usage

import torch

# mock model using x-transformer

from x_transformers import Encoder
model = Encoder(dim = 512, depth = 6)

# get RNNify module wrapper

from gamengen_pytorch import RNNify

# wrap the model, and pass in the module names where hidden state

rnn = RNNify(
    model,
    input_module_or_path = 'layers.0.2',
    output_module_or_path = 'layers.11.2',
)

x = torch.randn(1, 1024, 512)

out1, hiddens1 = rnn(x)
out2, hiddens2 = rnn(x, hiddens_for_rnn = hiddens1.detach())
out3, hiddens3 = rnn(x, hiddens_for_rnn = hiddens2.detach())
