AttributeError: 'bytes' object has no attribute 'encode'

Hello,

I got this exception when importing SRU :

Hi,

The new version of pynvrtc assumes bytes objects instead of str objects as input to Program().

You can fix the error by removing encode('utf-8') and encode() call in:

_SRU_PROG = Program(SRU_CODE.encode('utf-8'), 'sru_prog.cu'.encode())
