How do you reshape an array to 2D in Python?
Let’s use this to convert our 1D numpy array to 2D numpy array,
- arr = np. array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9])
- # Convert 1D array to a 2D numpy array of 2 rows and 3 columns.
- arr_2d = np. reshape(arr, (2, 5))
- print(arr_2d)

Use os. mkdir to create the directory. Then write the image to the proper path. Your best bet is write a function that accept fn as input as example saveImg(fn.) and then create folder if they doesn’t exist.
How do you reshape an array to 2D?
Use numpy. reshape() to reshape a 1D NumPy array to a 2D NumPy array. Call numpy. reshape(a, newshape) with a as a 1D array and newshape as the tuple (-1, x) to reshape the array to a 2D array containing nested arrays of x values each.
