  to run):

Using example file provided by repo does not work. I'm using the SPI version. So uncommenting the following line leads to the error above:
https://github.com/adafruit/Adafruit_Python_SSD1306/blob/master/examples/stats.py#L63
disp = Adafruit_SSD1306.SSD1306_128_64(rst=RST, dc=DC, spi=SPI.SpiDev(SPI_PORT, SPI_DEVICE, max_speed_hz=8000000))

How can I fix this?
