WebWe can reshape any array into any shape as long as the elements required for reshaping are equal in both shapes. Interestingly, we are allowed to have one “unknown” dimension. What that means is that you don’t have to specify an example number for one of the dimensions in the reshape method. WebYou can't use reshape()function, when the size of the original array is different from your desired reshaped array. If you try to reshape(), it will throw an error. Example my_arr = np.arange(8) print(my_arr) output will be [0,1,2,3,4,5,6,7] my_arr.reshape(2,3) the output will be an error as shown below
