RegressionPerfomanceTab not working ! about evidently HOT 3 CLOSED

Hi @pratikchhapolika !

The reason of this error is a misspelling in the Tab name. Instead of the “RegressionPerfomanceTab” there should be the “RegressionPerformanceTab”. I believe if you fix the name everything will be fine.

p.s. It is also important to make sure, that you imported this Tab earlier in your code correctly:
‘’’from evidently.tabs import RegressionPerformanceTab’’’
Here is an example of regression model analysis: https://github.com/evidentlyai/evidently/blob/main/evidently/examples/bike_sharing_demand_regression_performance.ipynb

The second part looks like you do not have either target or prediction (or both). To evaluate Categorical Target Drift it is necessary to have one of the target or prediction columns presented in both reference and current datasets. And if you do not provide the column mapping, then target column is expected to called ‘target’, prediction columns is expected to called ‘prediction’. It looks like you might fix the second issue by adding target column to your dataframes, for example like this:
‘’’iris_frame['target'] = iris.target’’’

Hope it will help!
If you share the structure of your dataframes I will be more specific with the solution.

Closing this issue. Thank you!
