[bug] Unable to import DetectPII from guardrails.hub

[sl2902]

I installed guardrails version 0.6.6 and ran guardrails configure. I then installed the package
from the hub guardrails hub install hub://guardrails/detect_pii; the following version 0.0.5 was installed successfully.
However, when I import from guardrails.hub import DetectPII, I encounter the error

     13 # Official Guardrails Hub imports
---> 14 from guardrails.hub import DetectPII, ToxicLanguage
     15 from guardrails import Guard
     16 

ImportError: cannot import name 'DetectPII' from 'guardrails.hub' (/usr/local/lib/python3.11/dist-packages/guardrails/hub/__init__.py)

On inspecting the file, the installation produces the following top level import
from guardrails_grhub_detect_pii import DetectPII
I was able to import the relevant module using the above import statement. Is this an issue with registering the validator?

The version of Python that I am running on is 3.11.13. I tested this on Jupyter Colab
