Genie2 - Pytorch (wip)

Implementation of a framework for Genie2 in Pytorch

Install

$ pip install genie2-pytorch

Usage

import torch
from genie2_pytorch import Genie2

genie = Genie2(
    dim = 512,
    depth = 12,
    dim_latent = 768,
    num_actions = 256,
    latent_channel_first = True,
    is_video_enc_dec = True
)

video = torch.randn(2, 768, 3, 2, 2)
actions = torch.randint(0, 256, (2, 3))

loss, breakdown = genie(video, actions = actions)
loss.backward()

generated_video = genie.generate(video[:, :, 0], num_frames = 16)

assert generated_video.shape == (2, 768, 16 + 1, 2, 2)
