# Models
Diffusers contains pretrained models for popular algorithms and modules for creating the next set of diffusion models.
The primary function of these models is to denoise an input sample, by modeling the distribution $p_\theta(\mathbf{x}_{t-1}|\mathbf{x}_t)$.
The models are built on the base class ['ModelMixin'] that is a `torch.nn.module` with basic functionality for saving and loading models both locally and from the HuggingFace hub.
## API
Models should provide the `def forward` function and initialization of the model.
All saving, loading, and utilities should be in the base ['ModelMixin'] class.
## Examples
- The ['UNetModel'] was proposed in [TODO](https://arxiv.org/) and has been used in paper1, paper2, paper3.
- Extensions of the ['UNetModel'] include the ['UNetGlideModel'] that uses attention and timestep embeddings for the [GLIDE](https://arxiv.org/abs/2112.10741) paper, the ['UNetGradTTS'] model from this [paper](https://arxiv.org/abs/2105.06337) for text-to-speech, ['UNetLDMModel'] for latent-diffusion models in this [paper](https://arxiv.org/abs/2112.10752), and the ['TemporalUNet'] used for time-series prediciton in this reinforcement learning [paper](https://arxiv.org/abs/2205.09991).

# Diffusers for other modalities
Diffusers offers support to other modalities than vision and audio.
Currently, some examples include:
- [Diffuser](https://diffusion-planning.github.io/) for planning in reinforcement learning (currenlty only inference): [![Open In Colab](https://colab.research.google.com/assets/colab-badge.svg)](https://colab.research.google.com/drive/1TmBmlYeKUZSkUZoJqfBmaicVTKx6nN1R?usp=sharing)
If you are interested in contributing to under-construction examples, you can explore: # Quicktour
- [GeoDiff](https://github.com/MinkaiXu/GeoDiff) for generating 3D configurations of molecule diagrams [![Open In Colab](https://colab.research.google.com/assets/colab-badge.svg)](https://colab.research.google.com/drive/1pLYYWQhdLuv1q-JtEHGZybxp2RBF8gPs?usp=sharing).

# Diffusers for vision
## Direct image generation
#### **Example image generation with PNDM**
```python
from diffusers import PNDM, UNetModel, PNDMScheduler
import PIL.Image
import numpy as np
import torch
model_id = "fusing/ddim-celeba-hq"
model = UNetModel.from_pretrained(model_id)
scheduler = PNDMScheduler()
# load model and scheduler
pndm = PNDM(unet=model, noise_scheduler=scheduler)
# run pipeline in inference (sample random noise and denoise)
with torch.no_grad():
image = pndm()
# process image to PIL
image_processed = image.cpu().permute(0, 2, 3, 1)
image_processed = (image_processed + 1.0) / 2
image_processed = torch.clamp(image_processed, 0.0, 1.0)
image_processed = image_processed * 255
image_processed = image_processed.numpy().astype(np.uint8)
image_pil = PIL.Image.fromarray(image_processed[0])
# save image
image_pil.save("test.png")
```
#### **Example 1024x1024 image generation with SDE VE**
See [paper](https://arxiv.org/abs/2011.13456) for more information on SDE VE.
```python
from diffusers import DiffusionPipeline
import torch
import PIL.Image
import numpy as np
torch.manual_seed(32)
score_sde_sv = DiffusionPipeline.from_pretrained("fusing/ffhq_ncsnpp")
# Note this might take up to 3 minutes on a GPU
image = score_sde_sv(num_inference_steps=2000)
image = image.permute(0, 2, 3, 1).cpu().numpy()
image = np.clip(image * 255, 0, 255).astype(np.uint8)
image_pil = PIL.Image.fromarray(image[0])
# save image
image_pil.save("test.png")
```
#### **Example 32x32 image generation with SDE VP**
See [paper](https://arxiv.org/abs/2011.13456) for more information on SDE VE.
```python
from diffusers import DiffusionPipeline
import torch
import PIL.Image
import numpy as np
torch.manual_seed(32)
score_sde_sv = DiffusionPipeline.from_pretrained("fusing/cifar10-ddpmpp-deep-vp")
# Note this might take up to 3 minutes on a GPU
image = score_sde_sv(num_inference_steps=1000)
image = image.permute(0, 2, 3, 1).cpu().numpy()
image = np.clip(image * 255, 0, 255).astype(np.uint8)
image_pil = PIL.Image.fromarray(image[0])
# save image
image_pil.save("test.png")
```
#### **Text to Image generation with Latent Diffusion**
_Note: To use latent diffusion install transformers from [this branch](https://github.com/patil-suraj/transformers/tree/ldm-bert)._
```python
from diffusers import DiffusionPipeline
ldm = DiffusionPipeline.from_pretrained("fusing/latent-diffusion-text2im-large")
generator = torch.manual_seed(42)
prompt = "A painting of a squirrel eating a burger"
image = ldm([prompt], generator=generator, eta=0.3, guidance_scale=6.0, num_inference_steps=50)
image_processed = image.cpu().permute(0, 2, 3, 1)
image_processed = image_processed * 255.0
image_processed = image_processed.numpy().astype(np.uint8)
image_pil = PIL.Image.fromarray(image_processed[0])
# save image
image_pil.save("test.png")
```
## Text to image generation
```python
import torch
from diffusers import BDDMPipeline, GradTTSPipeline
torch_device = "cuda"
# load grad tts and bddm pipelines
grad_tts = GradTTSPipeline.from_pretrained("fusing/grad-tts-libri-tts")
bddm = BDDMPipeline.from_pretrained("fusing/diffwave-vocoder-ljspeech")
text = "Hello world, I missed you so much."
# generate mel spectograms using text
mel_spec = grad_tts(text, torch_device=torch_device)
# generate the speech by passing mel spectograms to BDDMPipeline pipeline
generator = torch.manual_seed(42)
audio = bddm(mel_spec, generator, torch_device=torch_device)
# save generated audio
from scipy.io.wavfile import write as wavwrite
sampling_rate = 22050
wavwrite("generated_audio.wav", sampling_rate, audio.squeeze().cpu().numpy())
```
