thearmchair47 commented 12 months ago

Describe the bug It seems some packages used in Chainladder have been updated and are leading to errors when using the package.

To Reproduce Steps to reproduce the behavior. Code should be self-contained and runnable against publicly available data. For example:

import chainladder as cl
triangle = cl.load_sample('raa')

Expected behavior raa data to be imported, or any action that does not lead to an error. Result when running: ValueError: Unit M is not supported. Only unambiguous timedelta values durations are supported. Allowed units are 'W', 'D', 'h', 'm', 's', 'ms', 'us', 'ns'

We've updated chainladder to be compliant with pandas>=2.0, but I think that was after chainladder==0.8.14. Can you try upgrading chainladder to 0.8.18 and see if that resolves your issue?
