A step-by-step guide on how to check if a NumPy array is multidimensional or one-dimensional in multiple ways.
1- eps)# This happens in cases when elements in y_pred have type "str".ifnotisinstance(Y, np.ndarray):raiseValueError("y_pred should be an array of floats.")# If y_pred is of single dimension, assume y_true to be binary# and then check.ifY.ndim ==1:...
When we pass a list or numpy array of elements to theisna()function, theisna()function is executed with each element of the array. After execution, it returns a list or array containing True and False values. The False values of the output array correspond to all the values that are not...
Parameter.checkArray(Y)ifnumpy.unique(Y).shape[0] <2:raiseValueError("Vector of labels must be binary, currently numpy.unique(Y) = "+ str(numpy.unique(Y)))#If Y is 1D make it 2DifY.ndim ==1: Y = numpy.array([Y]).T
# Perform data validation after removing infinite values (numpy.inf) # from the given distance matrix. X = self._validate_data(X, force_all_finite=False, dtype=np.float64) X = self._validate_data( X, force_all_finite=False, dtype=np.float64, force_writeable=True ) if np.isnan(X)...
When we pass a list or numpy array to thenotnull()function, it returns a numpy array containing True and False values. You can observe this in the following example. import pandas as pd import numpy as np x=[1,2,pd.NA,4,5,None, 6,7,np.nan] ...
