Expected Behavior

Should just work

Additional Context

Fresh python 3.9.10 env, we catched this on our CI, I was using newer pythons on my computer.

Suggested Solutions

bump requirements or change Final[Optional]

[907Resident]

I am having a similar issue as well. I am using:

• mistral==1.1.0 (I have also tried a v1.0.3 without sucesss)
• pydantic==2.9.1
• pydantic-core==2.23.3
• typing-inspect==0.9.0
• eval-type-backport==0.2.0

When I run from mistralai import Mistral, I am getting the following error:

When I run from mistralai import Mistral, I am getting the following error:

[logan-markewich]

If the package isn't compatible with 3.9, thats fine, but the requirements should be raised on the package then

[GaspardBT]

Thanks for flagging the issue 🙇
We are investigating how we can support python = "^3.8", we will update shortly by fixing the issue or updating the requirements.

[GaspardBT]

Hey 👋
We released a new version of the SDK that fixes the compatibility issue with python 3.9, let us know if you still encounter the issue.
Sorry for the long wait 🙇
