Hi guys,
I encountered a TypeError when trying to import pyam in my environment this morning. My installation code looks like this:
!pip install ixmp4 numpy==1.23.5
!pip install pyam-iamc numpy==1.23.5
!pip install dask_expr numpy==1.23.5
import ixmp4
import pyam
Here’s the error trace:
TypeError: cannot inherit frozen dataclass from a non-frozen one
The error appears to occur within the Python dataclasses module, specifically:
TypeError: cannot inherit frozen dataclass from a non-frozen one
Any guidance on resolving this or insight into potential version incompatibilities would be much appreciated.
Thank you!
