Azure:如何使用tensorflow部署函数应用程序

Question

我正在尝试部署the TensorFlow sample from Microsoft到 azure (它在本地工作)。我所做的唯一更改是requirements.txt 中的TensorFlow 版本。我没有指定版本，而是将其留空，因为出现了错误:

ERROR: Could not find a version that satisfies the requirementtensorflow==1.14 (from -r requirements.txt (line 4)) (from versions:2.5.0, 2.5.1, 2.5.2, 2.5.3, 2.6.0rc0, 2.6.0rc1, 2.6.0rc2, 2.6.0, 2.6.1, 2.6.2, 2.6.3, 2.6.4, 2.6.5, 2.7.0rc0, 2.7.0rc1, 2.7.0, 2.7.1, 2.7.2, 2.7.3, 2.7.4, 2.8.0rc0, 2.8.0rc1, 2.8.0, 2.8.1, 2.8.2, 2.8.3, 2.9.0rc0, 2.9.0rc1, 2.9.0rc2, 2.9.0, 2.9.1, 2.9.2, 2.10.0rc0, 2.10.0rc1, 2.10.0rc2, 2.10.0rc3, 2.10.0)

azure-functions
#tensorflow==1.14
tensorflow
Pillow
requests

添加TensorFlow需求后部署不成功:

不幸的是，错误消息没有给我任何关于如何解决此问题的提示。你有什么主意吗？我使用 VS Code 中的集成工具来执行发布。使用 CLI，我得到了相同的结果:

您需要指定tensorflow 2.8，这为我解决了问题。在函数requirements.txt文件中输入“tensorflow==2.8.0”，而不仅仅是“tensorflow”
