Error: cannot connect to redis server

[mercuriaretrograda]

Hello!
I'm currently on step 8 of Writing pre-recorded data from HDD to the buffer (https://github.com/eegsynth/eegsynth/blob/master/doc/tutorial1.md) and I keep getting the same error, "Cannot connect to redis server" although redis server is open and working.
Any clue?

hal-9000:~ mariana$ redis-cli ping
PONG
hal-9000:~ mariana$ cd eegsynth/module/playbacksignal
hal-9000:playbacksignal mariana$ ls
README.md dump.rdb playbacksignal.ini playbacksignal.py
hal-9000:playbacksignal mariana$ python3 playbacksignal.py -i ../../inifiles/playbacksignal.ini
File "playbacksignal.py", line 57
print "Error: cannot connect to redis server"
^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print("Error: cannot connect to redis server")?

Hi, It seems you are attempting to run the eegsynth from Python 3. The "missing parentheses" error is a change between Python 2 and Python 3; in Python 2, the syntax : print "whatever" was still acceptable while in python 3 you have to write : print("whatever") The reason behind the eegsynth being written for Python 2 is for compatibility with Raspberry Pi, if I'm correct. I would suggest running a virtual environment (for example, using miniconda) under python 2 when you need to run the EEGSYNTH. https://conda.io/docs/user-guide/tasks/manage-environments.html Cheers Nicolas
