module 'epd' has no attribute 'EPD47'

[Kevin-Palmerini]

Hello!
I would like to test the demo app to send bitmap images to LILYGO T5-4.7 S3 E-Paper.
But I'm having difficulties installing the right packages for "epd", since the module EPD47 is not found.
I have basically followed the basic instruction like:

sudo apt-get install git make python3 python3-pip cmake quilt

and

$ cp config_T5-4.7-Plus config $ make

Could you please help me or give me any hints.
Thank you!!
