fast.ai seach_images_bing抛出PermissionDenied错误

如何解决fast.ai seach_images_bing抛出PermissionDenied错误

我在Gradient GPU服务器上关注fast.ai的jupyter笔记本教程。在第二个笔记本02_production.ipynb中，search_images_bing失败。

!pip install -Uqq fastbook
import fastbook
fastbook.setup_book()

from fastbook import *
from fastai.vision.widgets import *

key = os.environ.get('AZURE_SEARCH_KEY','XXX') # not showing my key :)
results = search_images_bing(key,'grizzly bear',min_sz=128)
ims = results.attrgot('content_url')

错误：

---------------------------------------------------------------------------

ErrorResponseException: Operation returned an invalid status code 'PermissionDenied'

我已经在Azure / Bing.Search.v7 / F1（免费版）上正确注册并设置了API，并获取了密钥。

如何通过与bing API对话来克服此错误？

解决方法

似乎最新版本的Bing Search使用fast.ai的search_images_bing函数中断了连接。

在https://forums.fast.ai/t/02-production-permissiondenied-error/65823/25?u=retuso处的解决方法上进行了改进，我能够创建一个搜索功能的本地实例，该实例可以（几乎）完全适合笔记本其余部分的自然使用。

本地功能：

def search_images_bing(key,term,max_images: int = 100,**kwargs):    
    params = {'q':term,'count':max_images}
    headers = {"Ocp-Apim-Subscription-Key":key}
    search_url = "https://api.bing.microsoft.com/v7.0/images/search"
    response = requests.get(search_url,headers=headers,params=params)
    response.raise_for_status()
    search_results = response.json() 
   
    # returns an L object to be identical to the original function.
    return L(search_results['value'])

调用该函数的代码，注意新的bing API不使用原始的content_url标签，而是使用contentUrl：

# fits in nicely with the original code
results = search_images_bing(key,'grizzly bear',min_sz=128)
ims = results.attrgot('contentUrl')

注意：我还没有使用min_sz参数。
