无法使用 Python 让语义内核在 Azure Web 应用程序中工作

Question

我正在尝试使用 Python 让语义内核在 Azure Web 应用程序中工作。我正在使用 VS 代码。每次我“部署到 Web 应用程序”时，其中有一个包含以下内容的 Python 脚本： from Semantic_kernel import Kernel，当我尝试访问我的 Azure Web 应用程序时，我会收到一条错误消息，显示“:( 应用程序错误” .

我已经确认我的 requiremnets.txt 文件中有正确的包（见下文），我尝试使用安装的本地依赖项进行部署，我使用的是 Python 3.10，这就是 Azure 环境所使用的。语义内核在本地工作得很好，但在 Azure 中却不行。如果我删除与语义内核相关的所有行并重新部署，我可以再次访问我的 Azure Web 应用程序，当然无需语义内核功能。

需求.txt：

Flask==3.0.3
PyMuPDF==1.24.13
Werkzeug==3.0.6
openai==1.55.0
azure-core==1.31.0
azure-ai-formrecognizer==3.3.3
pytesseract==0.3.13
Pillow==11.0.0
beautifulsoup4==4.12.3
requests==2.32.3
urllib3==2.2.3
pandas==2.2.3
openpyxl==3.1.5
semantic-kernel==1.12.1
azure-storage-blob==12.24.0
nest-asyncio==1.6.0

以下是我的app.py代码。其中唯一相关的部分是 pdf_comparison.py 代码。其他一切都工作正常，直到我将“导入语义_内核”添加到我的 pdf_comparison.py 文件中（也在下面）。

Answer 1

我已经尝试了您的代码并成功将其部署到 Azure Web App，没有任何问题。

。版本不兼容 (pydantic)：当前版本 (2.9.2) 与语义内核要求冲突。

• 您遇到的问题是因为版本不兼容，我使用时遇到了同样的错误

  semantic-kernel==1.12.1

• 当您使用

  pydantic==2.9.2

  时，您需要使用

  semantic-kernel==1.16.0

  来实现兼容性。
• 内核可能在本地计算机上运行良好，因为设置不同，但是当您将其部署到 Azure 时，它可能需要一些调整才能顺利运行，特别是对于在后台运行的任务。
• 所以，我将语义内核更新为

  1.16.0

我的requirements.txt：

Flask==3.0.3
PyMuPDF==1.24.13
Werkzeug==3.0.6
openai==1.55.0
azure-core==1.31.0
azure-ai-formrecognizer==3.3.3
pytesseract==0.3.13
Pillow==11.0.0
beautifulsoup4==4.12.3
requests==2.32.3
urllib3==2.2.3
pandas==2.2.3
openpyxl==3.1.5
semantic-kernel==1.16.0
azure-storage-blob==12.24.0
nest-asyncio==1.6.0
gunicorn==21.2.0
pydantic==2.9.2

本地输出：

更新包后，我可以成功将应用程序部署到Azure Web App。
