## 🎉 News
-- [🔥🔥🔥2024.10]: We are pleased to announce the release of the code for [ACE](https://arxiv.org/abs/2410.00086), supporting Customized Training / Comfy UI Workflow / gradio-based ChatBot Interface. The detailed documents can be found at [ACE repo](https://github.com/ali-vilab/ACE.git).
+- [🔥🔥🔥2024.11]: We're excited to announce the upcoming release of the [ACE-0.6b-1024px](https://huggingface.co/scepter-studio/ACE-0.6B-1024px) model,
+which significantly enhances image generation quality compared with [ACE-0.6b-512px](https://huggingface.co/scepter-studio/ACE-0.6B-512px). The detailed documents can be found at [ACE repo](https://github.com/ali-vilab/ACE.git).
+At the same time, based on the editing results of ACE, combined with the powerful text-to-image capabilities of the [FLUX-dev](https://huggingface.co/black-forest-labs/FLUX.1-dev) model through SDEdit as an image quality refiner, the quality of image editing can be further enhanced.
+- [🔥2024.11]: Supports video files, video annotation, caption translation in data management, and inference & training of the [CogVideoX](https://arxiv.org/abs/2408.06072).

- [2024.09]: We introduce **ACE**, an **A**ll-round **C**reator and **E**ditor adept at executing a diverse array of image editing tasks tailored to your specifications. Built upon the cutting-edge Diffusion Transformer architecture, ACE has been extensively trained on a comprehensive dataset to seamlessly interpret and execute any natural language instruction. For further information, please consult the [project page](https://ali-vilab.github.io/ace-page/).

+## 🪄ACE
ACE is a unified foundational model framework that supports a wide range of visual generation tasks. By defining CU for unifying multi-modal inputs across different tasks and incorporating long-context CU, we introduce historical contextual information into visual generation tasks, paving the way for ChatGPT-like dialog systems in visual generation.

-### Launch
+We support the use of all models in the ComfyUI Workflow through the following methods:
-Manually install by moving custom_nodes to ComfyUI.
+1) Automatic installation directly via the ComfyUI Manager by searching for the **ComfyUI-Scepter** node.
+2) Manually install by moving custom_nodes from Scepter to ComfyUI.
```shell
+git clone https://github.com/modelscope/scepter.git
cd path/to/scepter
pip install -e .
cp -r path/to/scepter/workflow/ path/to/ComfyUI/custom_nodes/ComfyUI-Scepter
cd path/to/ComfyUI
python main.py
```
-In addition, we also support installation and usage through the ComfyUI Manager.
+**Note**: You can use the nodes by dragging the sample images into ComfyUI. Additionally, our nodes can automatically pull models from ModelScope or HuggingFace by selecting the *model_source* field, or you can place the already downloaded models in a local path.

+ """
+ A Transformer model for video-like data in [CogVideoX](https://github.com/THUDM/CogVideo).
+
+ Parameters:
+ num_attention_heads (`int`, defaults to `30`):
+ The number of heads to use for multi-head attention.
+ attention_head_dim (`int`, defaults to `64`):
+ The number of channels in each head.
+ in_channels (`int`, defaults to `16`):
+ The number of channels in the input.
+ out_channels (`int`, *optional*, defaults to `16`):
+ The number of channels in the output.
+ flip_sin_to_cos (`bool`, defaults to `True`):
+ Whether to flip the sin to cos in the time embedding.
+ time_embed_dim (`int`, defaults to `512`):
+ Output dimension of timestep embeddings.
+ text_embed_dim (`int`, defaults to `4096`):
+ Input dimension of text embeddings from the text encoder.
+ num_layers (`int`, defaults to `30`):
+ The number of layers of Transformer blocks to use.
+ dropout (`float`, defaults to `0.0`):
+ The dropout probability to use.
+ attention_bias (`bool`, defaults to `True`):
+ Whether or not to use bias in the attention projection layers.
+ sample_width (`int`, defaults to `90`):
+ The width of the input latents.
+ sample_height (`int`, defaults to `60`):
+ The height of the input latents.
+ sample_frames (`int`, defaults to `49`):
+ The number of frames in the input latents. Note that this parameter was incorrectly initialized to 49
+ instead of 13 because CogVideoX processed 13 latent frames at once in its default and recommended settings,
+ but cannot be changed to the correct value to ensure backwards compatibility. To create a transformer with
+ K latent frames, the correct value to pass here would be: ((K - 1) * temporal_compression_ratio + 1).
+ patch_size (`int`, defaults to `2`):
+ The size of the patches to use in the patch embedding layer.
+ temporal_compression_ratio (`int`, defaults to `4`):
+ The compression ratio across the temporal dimension. See documentation for `sample_frames`.
+ max_text_seq_length (`int`, defaults to `226`):
+ The maximum sequence length of the input text embeddings.
+ activation_fn (`str`, defaults to `"gelu-approximate"`):
+ Activation function to use in feed-forward.
+ timestep_activation_fn (`str`, defaults to `"silu"`):
+ Activation function to use when generating the timestep embeddings.
+ norm_elementwise_affine (`bool`, defaults to `True`):
+ Whether or not to use elementwise affine in normalization layers.
+ norm_eps (`float`, defaults to `1e-5`):
+ The epsilon value to use in normalization layers.
+ spatial_interpolation_scale (`float`, defaults to `1.875`):
+ Scaling factor to apply in 3D positional embeddings across spatial dimensions.
+ temporal_interpolation_scale (`float`, defaults to `1.0`):
+ Scaling factor to apply in 3D positional embeddings across temporal dimensions.

+ A VAE model with KL loss for encoding images into latents and decoding latent representations into images. Used in
+ [CogVideoX](https://github.com/THUDM/CogVideo).
+
+ This model inherits from [`ModelMixin`]. Check the superclass documentation for it's generic methods implemented
+ for all models (such as downloading or saving).
+
+ Parameters:
+ in_channels (int, *optional*, defaults to 3): Number of channels in the input image.
+ out_channels (int, *optional*, defaults to 3): Number of channels in the output.
+ down_block_types (`Tuple[str]`, *optional*, defaults to `("DownEncoderBlock2D",)`):
+ Tuple of downsample block types.
+ up_block_types (`Tuple[str]`, *optional*, defaults to `("UpDecoderBlock2D",)`):
+ Tuple of upsample block types.
+ block_out_channels (`Tuple[int]`, *optional*, defaults to `(64,)`):
+ Tuple of block output channels.
+ act_fn (`str`, *optional*, defaults to `"silu"`): The activation function to use.
+ sample_size (`int`, *optional*, defaults to `32`): Sample input size.
+ scaling_factor (`float`, *optional*, defaults to `1.15258426`):
+ The component-wise standard deviation of the trained latent space computed using the first batch of the
+ training set. This is used to scale the latent space to have unit variance when training the diffusion
+ model. The latents are scaled with the formula `z = z * scaling_factor` before being passed to the
+ diffusion model. When decoding, the latents are scaled back to the original scale with the formula: `z = 1
+ / scaling_factor * z`. For more details, refer to sections 4.3.2 and D.1 of the [High-Resolution Image
+ Synthesis with Latent Diffusion Models](https://arxiv.org/abs/2112.10752) paper.
+ force_upcast (`bool`, *optional*, default to `True`):
+ If enabled it will force the VAE to run in float32 for high image resolution pipelines, such as SD-XL. VAE
+ can be fine-tuned / trained to a lower range without loosing too much precision in which case
+ `force_upcast` can be set to `False` - see: https://huggingface.co/madebyollin/sdxl-vae-fp16-fix
