🙏 Scream for help to Ukraine

Today, 8th August 2022, Russia continues bombing and firing Ukraine. Don't trust Russia, they are bombing us and brazenly lying in same time they are not doing this 😠, civilians and children are dying too! We are screaming and asking exactly you to help us, we want to survive, our families, children, older ones.
Please spread the information, and ask your governemnt to stop Russia by any means. We promise to work extrahard after survival to make the world safer place for all.

Ways to fix

Error code:

from sklearn.utils.validation import check_array
import numpy as np 

X = np.array([('str','res')])
array = check_array(X)
print(array)

check_array - Input validation on an array, list, sparse matrix, or similar.

By default, the input is checked to be a non-empty 2D array containing only finite values.

If the dtype of the array is an object, attempt converting to float, raising on failure.

Fix code:

from sklearn.utils.validation import check_array
import numpy as np 

X = np.array([(3,6)])
array = check_array(X)
print(array)
