Thanks for that.
I already had some of the files installed from a previous attempt.
In the luma.examples/examples folder, I edited the clock.py script to
include:

from luma.core.interface.serial import i2c, spi
from luma.core.render import canvas
from luma.oled.device import ssd1306, ssd1309, ssd1325, ssd1331, sh1106

but edited the last line to just
from luma.oled.device import ssd1327.

When I ran the script :
pi@raspberrypi:~/luma.examples/examples $ python clock.py
Version: luma.oled 3.3.0 (luma.core 1.12.0)
Display: ssd1306
Interface: i2c
Dimensions: 128 x 64

and there was no errors and nothing on the display.
