Using Google Colab to run a Stable Diffusion pipeline

Here are the detailed steps to start using Google Colab:

1. Create a new instance from https://colab.research.google.com/.
2. Click Runtime | Change runtime type and select T4 GPU, as shown in Figure 2.4:

3. Create a new cell and use the following command to check whether the GPU and CUDA are working:

   !nvidia-smi

4. Install the packages for Hugging Face Diffusers:

   !pip install diffusers

   !pip install transformers scipy ftfy accelerate ipywidgets

5. Start a Stable Diffusion pipeline:

   import torch

   from diffusers import StableDiffusionPipeline

   pipe = StableDiffusionPipeline.from_pretrained(

       "runwayml/stable-diffusion-v1-5",

        torch_dtype=torch.float16)

   pipe.to("cuda")

6. Generate an image:

   prompt = "a photo of an astronaut riding a horse on mars,blazing fast, wind and...
