I am currently working with the Ultracortex Mark 4 with the Cyton Daisy
Board. My goal is to build an application around the principle of Motor
Imagery to be able to control objects in Unity. I was able to find out from
the documentation that LSL can be used for this purpose. Unfortunately I
have problems to get LSL4Unity to work with the OpenBCI.

I tried to use LSL with Python first and used the instructions at this link:
"https://docs.openbci.com/Software/CompatibleThirdPartySoftware/LSL/"
Now I have the problem that some packages in the script do not work and I get a
lot of error messages. I get the following errors according to the current status:

Traceback (most recent call last):

  class GraphicsScene(QtGui.QGraphicsScene):
AttributeError: module 'PyQt5.QtGui' has no attribute 'QGraphicsScene'.

Is there any further support or solutions for this in any way?
Unfortunately, I have to admit that I have very little experience with
programming in general, so surely one or the other error may have been
caused by my lack of knowledge. Nevertheless, I would be very happy about
feedback, because I am very interested in working with BCI and I want to
write my master thesis about it.

Kind regards,
Florian
