## MMDiT
Implementation of a single layer of the MMDiT, proposed by Esser et al. in <a href="https://arxiv.org/abs/2403.03206">Stable Diffusion 3</a>, in Pytorch
Besides a straight reproduction, will also generalize to > 2 modalities, as I can envision an MMDiT for images, audio, and text.
Will also offer an improvised variant of the attention that adaptively selects the weights to use through learned gating.
## Install
```bash
$ pip install mmdit
```
## Usage
```python
import torch
from mmdit import MMDiTBlock
# define mm dit block
block = MMDiTBlock(
dim_joint_attn = 512,
dim_cond = 256,
dim_text = 768,
dim_image = 512,
qk_rmsnorm = True
)
# mock inputs
time_cond = torch.randn(1, 256)
text_tokens = torch.randn(1, 512, 768)
text_mask = torch.ones((1, 512)).bool()
image_tokens = torch.randn(1, 1024, 512)
# single block forward
text_tokens_next, image_tokens_next = block(
time_cond = time_cond,
text_tokens = text_tokens,
text_mask = text_mask,
image_tokens = image_tokens
)
```
A generalized version can be used as so
```python
import torch
from mmdit.mmdit_generalized_pytorch import MMDiT
mmdit = MMDiT(
depth = 2,
dim_modalities = (768, 512, 384),
dim_joint_attn = 512,
dim_cond = 256,
qk_rmsnorm = True
)
# mock inputs
time_cond = torch.randn(1, 256)
text_tokens = torch.randn(1, 512, 768)
text_mask = torch.ones((1, 512)).bool()
video_tokens = torch.randn(1, 1024, 512)
audio_tokens = torch.randn(1, 256, 384)
# forward
text_tokens, video_tokens, audio_tokens = mmdit(
modality_tokens = (text_tokens, video_tokens, audio_tokens),
modality_masks = (text_mask, None, None),
time_cond = time_cond,
)
```
