Error message when using validator

[lopierra]

Hi @madanucd - I'm attempting to run the validator on a test dataset:

validate-data -o ./errorlogs ./ABC-DS.csv participant

but I get the following error message:

Traceback (most recent call last):

AttributeError: 'DataFrame' object has no attribute 'map'. Did you mean: 'max'?

Am I doing something wrong, or is it an issue with the validator?

Not urgent - we can discuss next Tuesday at Data Modeling meeting. Thanks!

It seems the map function is executing on my local machine, but typically, map cannot be directly applied to a DataFrame. To ensure consistency and correctness, we should update it to use applymap or apply which are the appropriate methods for applying functions to DataFrame elements. I will be preparing a PR to make this adjustment.

Hi Pierrette,

I wanted to bring to your attention that the applymap function has been deprecated for pandas versions after 2.1.0. You can find more details in the pandas documentation here. It was working for me because my pandas version is 2.2.0.

We could switch to using applymap as suggested in earlier versions of pandas. However, please note that with future pandas updates, it might not work.

Could you please try updating your pandas version? This should resolve the issue.

Thank you!

@madanucd I updated pandas and got a bit further with the validator. I ran it on the same file that I sent you before (ABC-DS.csv) and got the expected validation errors, but also got a TypeError. Is this expected? (Maybe due to ABC-DS having IDs that are integers instead of strings?)
