Hello Rohit Kulkarni,

Welcome to the MS Q&A platform.

As per the error message, it seems like you are passing a singleton array (an array with only one element) as an argument to the classification_report function. This is causing the function to raise a TypeError.

Please check the shape of your ytest and ytest_predict arrays to ensure that they have the same number of elements

import numpy as np

print(np.array(ytest).shape)

print(np.array(ytest_predict).shape)

If the shapes are the same then you can try reshaping the singleton array to be a one dimensional array using the np.ravel(), , which should be a valid collection for the classification_report function.

print(classification_report(ytest,np.ravel(ytest_predict)))

If you are still facing the error, please provide more context or code snippets to understand the issue better.
