This function is used to generate images using our fine-tuned keras dreambooth stable diffusion model.
Args:
prompt (str): The text input given by the user based on which images will be generated.
negative_prompt (srt): The text to eliminate from the generation some concepts.
num_imgs_to_gen (int): The number of images to be generated using given prompt.
num_steps (int): The number of denoising steps
guidance_scale (double): Increasing guidance makes generation follow more closely to the prompt.
Returns:
generated_img (List): List of images that were generated using the model
