Module 'cads_api_client' has no attribute 'legacy_api_client'

The visions of cdsapi(0.7.3) and cads_api_client(1.4.2) are all latest. Python vision is 3.11.
And I have already changed .cdsapirc into the latest.
Tried so many ways, still can’t figure it out. :sob: :sob:

I needed to run pip install --upgrade attrs to get it to work.
