A“1-D” and a “2-D” array is initialized in the program. The “for loop” iterates over each element of the “1-D” and “2-D” array and the print() function is used to print the array elements. Output: The input arrays have been printed on the screen. ...

arrays along a new axis. It is useful when you have numpy arrays in Python of the same shape and you want to join them in such a way that the result has one more dimension. For example, if you stack two 1D arrays, the result will be a 2D array with the input arrays as its ...
Result will never require gradient. If the input is volatile, the output will be volatile too. .. note:: Returned Variable uses the same data tensor, as the original one, and in-place modifications on either of them will be seen, and may trigger ...
