Any help fixing the problem would be greatly appreciated.
I am trying to deploy an old CNN model (MRCNN), last deployed in December 2020, on Azure ML studio using the Python SDK V2. After a successful deployment, when the image is built in the deployment, I run into this error:

The above exception was the direct cause of the following exception:

Based on my research, it could be due to a deprecated library. I am having a hard time identifying it and I wanted to ask here to see if there is a smarter/better way than manually going through each of the libraries.

I had to upgrade my Tensorflow to 2+ (I chose 2.0.0). Consequently, I had to modify my code to use Tensorflow v2. There are specific steps given on how to migrate to v2.
In my case, my code was MRCNN and there plenty of blogs/SO question/git repos which were helpful in properly migrating my code to V2.
TypeError: metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases
This is because of clashes between the metaclasses used in different classes or modules.
Mostly, updating or downgrading specific dependencies can resolve metaclass conflicts.
A specific package as the stable version for your requirement tensorflow==2.16.1 Add this to your config file
pip install -r requirements.txt --upgrade
Sometimes when Tensorflow 2 and "the application" is installed, as the error gets like ~ python AssertionError: only tensorflow v1 is supported .
Python 3.6 but downgrading to Python 3.6 is no longer supportedInstall the latest version with pip install 'tensorflow<2.0' and update it in requirements.txt or similar.
