Hi guys,I've tried with the following formula to make a blank array but in vain =LET(x,MAKEARRAY(2,2,LAMBDA(r,c,"")),ISBLANK(x))So what should I return...
If you want to generate a copy of an array, you can use np.copy(). Copying an array creates a new place in memory for the copy to be stored, so changes to the copied array do not affect the original: Python In [11]: arr_3 = np.copy(arr_2) In [12]: arr_3[1, 0] = ...

If int, random_state is the seed used by the random number generator; If RandomState instance, random_state is the random number generator; If None, the random number generator is the RandomState instance used by np.random. 输出: X : array of shape [n_samples, 10] 特征矩阵。 y : array...
