ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()
This error message is indicating that a boolean operation was performed on an array with multiple elements, and the result of the operation is ambiguous. To resolve this issue, you should use the .any() or .all() method on the array to specify how the boolean operation should be applied to the elements of the array.
For example, if you have an array a and you want to check if any of the elements are greater than 5, you can use the .any() method:
result = (a > 5).any()Alternatively, if you want to check if all of the elements are greater than 5, you can use the .all() method:
result = (a > 5).all()It is important to note that the .any() method will return True if any of the elements of the array are True, while the .all() method will only return True if all of the elements of the array are True.
