Azure: How to deploy a functions app with tensorflow-CodePudding

I am trying to deploy the TensorFlow sample from Microsoft to azure (it works locally). The only change I made is to TensorFlow version in the requirements.txt. Instead of specifying a version I left it blank because errors appeared:

ERROR: Could not find a version that satisfies the requirement tensorflow==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

The deployment is unsuccessful as soon as the TensorFlow requirement is added:

Unfortunately, the error message is not giving me any hint on how to solve this issue. Do you have any idea? I used the integrated tools in VS Code to perform the publish. Using the CLI, I get the same result tho:

>>> func azure functionapp publish Test19542413

CodePudding user response：

you need to specify tensorflow 2.8, that fixed the problem for me. in the function requirements.txt file put "tensorflow==2.8.0" instead of just "tensorflow"
