TypeError by starting stream #114

I'm getting this error message below when starting a normal lsl stream. Already tried to update python to 3.7 and changed the pygatt version.

Traceback (most recent call last): File "/home/usability/.local/bin/muselsl", line 10, in sys.exit(main()) File "/home/usability/.local/lib/python2.7/site-packages/muselsl/main.py", line 57, in main cli = CLI(args.command) File "/home/usability/.local/lib/python2.7/site-packages/muselsl/cli.py", line 9, in init getattr(self, command)() File "/home/usability/.local/lib/python2.7/site-packages/muselsl/cli.py", line 51, in stream args.interface, args.name, args.ppg, args.acc, args.gyro, args.disable_eeg) File "/home/usability/.local/lib/python2.7/site-packages/muselsl/stream.py", line 75, in stream 'Muse%s' % address) File "/home/usability/.local/lib/python2.7/site-packages/pylsl/pylsl.py", line 193, in init c_char_p(str.encode(source_id))) TypeError: descriptor 'encode' requires a 'str' object but received a 'unicode'

Thanks Guys :)!

descriptor 'encode' requires a 'str' object but received a 'unicode' says the the device name MUSE1234 is for some reason unicode type, and not string. Not sure why, but it doesn't seem a muselsl, nor a pylsl issue, but something in your setup. I would start by running python3, not python2.7 (ie. pip3 install muselsl)

I had the same issue. I fixed it by editing "/home/usability/.local/lib/python2.7/site-packages/pylsl/pylsl.py" line 193 c_char_p(str.encode(source_id))) --> c_char_p(unicode.encode(source_id)))
