I have two array one with shape (320,1) and one with (850,1) how should I combine the two array. I tried np.append however it seems to be an error.

CodePudding user response：

Assuming the two arrays are called arr1 and arr2, you could try the following code:

arr3 = np.append(arr1,arr2).reshape((-1,1))

The reshape is needed to make sure the final shape is (1170,1) instead of (1170,)
