TypeError: '<' not supported between instances of 'str' and 'int' when setting pval=True

[erdie721]

I'm getting the following error whenever I set pval=True on a data set. Using Jupyter Notebook via Anaconda running python 3.9

Can anyone help understanding this issue please ? I'm having the same issue.

The values are stratified, and are numeric, I don't understand where this issue is coming from ?
