🤖 AI解决方案
错误分析
1. 错误翻译
原文：Invalid URL (POST /v1/images/generations/images/generations)
译文：无效URL（POST /v1/images/generations/images/generations）2. 原因分析
- 根本原因：URL路径重复拼接导致的404错误
- 问题位置：在调用
client.images.generate()方法时，底层库错误地将路径拼接了两次 - 具体分析：从错误信息可以看出，实际的请求路径变成了
/v1/images/generations/images/generations，正确的应该是/v1/images/generations
3. 解决方案
方法一：检查client配置
# 正确的客户端配置
from openai import OpenAI
client = OpenAI(
api_key="your-api-key",
base_url="https://api.openai.com/v1" # 如果是OpenAI API
# 或者如果是其他兼容API
# base_url="https://your-api-endpoint/v1"
)
response = client.images.generate(
model="dall-e-3", # 使用正确的模型名称
prompt="3 picture of orange cat",
n=3,
size="1024x1024"
)方法二：使用正确的模型
# Gemini不是OpenAI的图像生成模型
response = client.images.generate(
model="dall-e-3", # 正确的图像生成模型
prompt="create 3 pictures of orange cat",
n=3,
size="1024x1024"
