 The following example will use the fast DPM scheduler to generate an image in ca. 2 seconds on a V100.
 
+First you should install diffusers main branch and some dependencies:
+```
+pip install git+https://github.com/huggingface/diffusers.git torch transformers sentencepiece
+```
+
+then you can run the following example:
+
 ```python
-!pip install git+https://github.com/huggingface/diffusers.git torch transformers
 from diffusers import AltDiffusionPipeline, DPMSolverMultistepScheduler
 import torch
 
-pipe = AltDiffusionPipeline.from_pretrained("../AltDiffusion", torch_dtype=torch.float16)
+pipe = AltDiffusionPipeline.from_pretrained("BAAI/AltDiffusion", torch_dtype=torch.float16)
 pipe = pipe.to("cuda")
 
 pipe.scheduler = DPMSolverMultistepScheduler.from_config(pipe.scheduler.config)
