ValueError: multiclass-multioutput is not supported

Dears, When I try to Calculate Confusion matrix, encountered an error Please support me as per the following error...

[owendw1]

It would be useful to see what y_test and y_pred look like immediately before the confusion_matrix method is called. Can you add the following two lines to your code immediately before the line _conf_matrix = confusion_matrix(y_test, ypred):

_print('y_test:', y_test) print('y_pred:', ypred)

Could you then post the output of those two lines (assuming the data is not sensitive)? They may provide clues.

[zelekemarew]

Ok, Let I send you the output...

I can see why confusion_matrix might not like the shape of either y_test or y_pred, but I think we need to understand how they're being arrived at.

Are you doing multilabel classification? We might need to see your full code to understand what it's aiming to do.

OK dear, Now I would like to give further clarification & some pieces of code as below:

1. My data have the following shapes.. [image: image.png]
2. Here is My Total Data Visualization [image: image.png]
3. From 46 columns, I select 33-best columns for my train & test purpose so that I Take 24-column data for training & the remaining 9- columns for tasting by 70/30 split & all of them are numeric column that hold one company energy consumption history [image: image.png] 4, After that, I already tested more than four (4) Prediction algorithms to test best accurate prediction model [image: image.png] [image: image.png]

[image: image.png]

5, Finally, I want to calculate confusion matrix..... Here I put the code that i traid with encountered error... as below [image: image.png] [image: image.png]

I think now you may understand my code... and if you are willing to support me, we can meet online, & I can show you the full code from start up to end Thanks for your Support.
