Name 'epd2in13_V2' is not defined
Closed this issue · 2 comments
I am trying to run this on a Raspberry Pi 3 model B with Kali Linux installed. When I run the main python script I get these errors:
Traceback (most recent call last): File "/home/kali/zero-btc-screen/main.py", line 60, in <module> main() File "/home/kali/zero-btc-screen/main.py", line 40, in main builder.bind(data_sink) File "/home/kali/zero-btc-screen/config/builder.py", line 23, in bind screen_class(observable=observable, **kwargs) File "/home/kali/zero-btc-screen/presentation/screens/epd2in13v2.py", line 23, in __init__ self.epd = self._init_display() File "/home/kali/zero-btc-screen/presentation/screens/epd2in13v2.py", line 30, in _init_display epd = epd2in13_V2.EPD() NameError: name 'epd2in13_V2' is not defined. Did you mean: 'Epd2in13v2'?
I have tried changing the name in the code and stuff like that but more errors kept coming up.
What can I do to fix this?
Hi @Jello-exe, based on the stack-trace it seems you haven't installed the e-paper drivers successfully.
Try going over the 3rd step of the installation process again, namely:
git clone https://github.com/waveshare/e-Paper.git ~/e-Paper
pip3 install ~/e-Paper/RaspberryPi_JetsonNano/python/
Looking forward to hear if this helps.
Thank you for the reply!
This is the output of those 2 commands:

I don't see anything weird in there.
