## Inference Requirements and Model Introduction
|
|
|
|
+ Resolution: Width and height must be between `512px` and `2048px`, divisible by `32`, and ensure the maximum number of pixels does not exceed `2^21` px.
|
|
+ Precision: BF16 / FP32 (FP16 is not supported as it will cause overflow resulting in completely black images)
|
|
|
|
Using `BF16` precision with `batchsize=4` for testing, the memory usage is shown in the table below:

## Quick Start
|
|
|
|
First, ensure you install the `diffusers` library from source.
|
|
|
|
```shell
|
|
pip install git+https://github.com/huggingface/diffusers.git
|
|
cd diffusers
|
|
pip install -e .
|
|
```
|
|
|
|
Then, run the following code:
|
|
|
|
```python
|
|
from diffusers import CogView4Pipeline
|
|
pipe = CogView4Pipeline.from_pretrained("THUDM/CogView4-6B", torch_dtype=torch.bfloat16)
|
|
|
|
# Open it for reduce GPU memory usage
|
|
pipe.enable_model_cpu_offload()
|
|
pipe.vae.enable_slicing()
|
|
pipe.vae.enable_tiling()
|
|
|
|
prompt = "A vibrant cherry red sports car sits proudly under the gleaming sun, its polished exterior smooth and flawless, casting a mirror-like reflection. The car features a low, aerodynamic body, angular headlights that gaze forward like predatory eyes, and a set of black, high-gloss racing rims that contrast starkly with the red. A subtle hint of chrome embellishes the grille and exhaust, while the tinted windows suggest a luxurious and private interior. The scene conveys a sense of speed and elegance, the car appearing as if it's about to burst into a sprint along a coastal road, with the ocean's azure waves crashing in the background."
|
|
image = pipe(
|
|
prompt=prompt,
|
|
guidance_scale=3.5,
|
|
num_images_per_prompt=1,
|
|
num_inference_steps=50,
|
|
width=1024,
|
|
height=1024,
|
|
).images[0]
|
|
|
|
image.save("cogview4.png")
|
|
```
|
|
