import name 'CaseInsensitiveDict' from 'azure.core.utils' when installing az extension

[huliang-microsoft]

Describe the bug

Hi Azure Cli team,
We are using Azure Devops to build our service and we started to see this failure when we tried to install extensions:

sudo az extension add --name quota --version 0.1.0 -y
cannot import name 'CaseInsensitiveDict' from 'azure.core.utils' (/opt/az/lib/python3.10/site-packages/azure/core/utils/init.py)

We installed azure cli with:
sudo apt-get install -y --allow-downgrades azure-cli=2.39.0-1~focal

The previous successful pipeline runs are also 2.39.0-1 so I dont know what changed.

Thanks

Hi @huliang-microsoft,

2.39.0 is not the latest Azure CLI(2.52.0).

If you haven't already attempted to do so, please upgrade to the latest Azure CLI version by following https://learn.microsoft.com/en-us/cli/azure/update-azure-cli.

Hi @huliang-microsoft
Find similar issue #23267.

Issue title	compatibility issues between azure-core and azure-cli: cannot import name 'case_insensitive_dict' from 'azure.core.utils'
Create time	2022-07-19
Comment number	14

Possible solution:
The error message "cannot import name 'CaseInsensitiveDict' from 'azure.core.utils'" is caused by compatibility issues between azure-core and azure-cli. Until cli 2.37.0, AZ CLI had the dependency azure-core==1.21.1. Starting 2.38.0, AZ CLI is having dependency azure-core==1.24.0. In case, we install a package that has a direct or indirect dependency on the lower azure-core==1.21.1, the AZ CLI encounters the compatibility issues between azure-core and azure-cli and emits the error: cannot import name 'case_insensitive_dict' from 'azure.core.utils'. To fix the issue, you can try installing azure-core==1.23.1 by running %pip install azure-core==1.23.1.

Hi @huliang-microsoft!
Az 2.39 is bit old now compared 2.52.
I helped resolve a similar issue recently from customer by suggesting him to "Az upgrade" and add Az ML extension after removal. Could you confirm it from your side.

1. az upgrade
2. az extension remove -n azure-cli-ml
3. az extension remove -n ml
4. az extension add -n ml

Reference - #21390
Thank you.
