简易的使用stable diffusion进行生成图片_stable difusion 如何循环生成图片

这个其实是ipynb文件(因为不会使用ipynb, 只能这样写), 每一个python框都是一个需要运行的code

stabel diffusion generate是收费的, 不过有100多张的免费额度, 也可以多使用几个邮箱注册, 然后白嫖

pip install stability-sdk

import os
import io

from PIL import Image
from stability_sdk import client
import stability_sdk.interfaces.gooseai.generation.generation_pb2 as generation

# Our Host URL should not be prepended with "https" nor should it have a trailing slash.

这里的STABILITY_KEY需要自己获取, 在key网址获取key

直接复制图片上的key即可

# Set up our connection to the API.
stability_api = client.StabilityInference(
    key=os.environ['STABILITY_KEY'], # API Key reference.
    verbose=True, # Print debug messages.
    engine="stable-diffusion-xl-1024-v1-0", # Set the engine to use for generation.
    # Check out the following link for a list of available engines: https://platform.stability.ai/docs/features/api-parameters#engine

width、height是根据需要自己设置

samples是生成的图片的数量

# Set up our initial generation parameters.
answers = stability_api.generate(
    # prompt="Early forest fire five kilometers away with very small white smoke above forest and very small flames in forest",
    prompt=" small white smoke above forest, tiny flame in forest",
    seed=4253978046, # If a seed is provided, the resulting generated image will be deterministic.
                     # What this means is that as long as all generation parameters remain the same, you can always recall the same image simply by generating it again.
                     # Note: This isn't quite the case for Clip Guided generations, which we'll tackle in a future example notebook.
    steps=50, # Amount of inference steps performed on image generation. Defaults to 30. 
    cfg_scale=8.0, # Influences how strongly your generation is guided to match your prompt.
                   # Setting this value higher increases the strength in which it tries to match your prompt.
                   # Defaults to 7.0 if not specified.
    width=1520, # Generation width, defaults to 512 if not included.
    height=1520, # Generation height, defaults to 512 if not included.
    samples=1, # Number of images to generate, defaults to 1 if not included.
    sampler=generation.SAMPLER_K_DPMPP_2M # Choose which sampler we want to denoise our generation with.
                                                 # Defaults to k_dpmpp_2m if not specified. Clip Guidance only supports ancestral samplers.
                                                 # (Available Samplers: ddim, plms, k_euler, k_euler_ancestral, k_heun, k_dpm_2, k_dpm_2_ancestral, k_dpmpp_2s_ancestral, k_lms, k_dpmpp_2m, k_dpmpp_sde)
)

# Set up our warning to print to the console if the adult content classifier is tripped.
# If adult content classifier is not tripped, save generated images.
for resp in answers:
    for artifact in resp.artifacts:
        if artifact.finish_reason == generation.FILTER:
            warnings.warn(
                "Your request activated the API's safety filters and could not be processed."
                "Please modify the prompt and try again.")
        if artifact.type == generation.ARTIFACT_IMAGE:
            img = Image.open(io.BytesIO(artifact.binary))
            img.save(str(artifact.seed)+ ".png") # Save our generated images with their seed number as the filename.
