Hi, I'm GitMate.io!

It seems you've just enabled the issue triaging. I'm just scraping all issues from your repository and will give you some more information about this in a few minutes or so.

Because of the rate limit we can't scrape all information (including all comments and authors) right now - our system is already set up to scrape this in the next days over which the predictions will become more precise every day.

If you want me to use a different account for triaging your issues, simply create one and log in with it.

Sit tight!

GitMate.io thinks possibly related issues are #4 (installing visbrain), and #12 (Brain import error).

I tried in ubuntu and in the windows . I have installed python 3.6.4 also python 3.6.5 also python 3.7.0 in this cases a i get the same error . pyqt installed matplotlib updated also vispy

[EtienneCmb]

Hello, what's the version of vispy? Because I think the latest version of vispy should not raise this error

[alexschn]

C:\Program Files (x86)\Python36-32\Scripts>pip install --upgrade vispy
Requirement already up-to-date: vispy in c:\program files (x86)\python36-32\lib\site-packages (0.5.3)
Requirement not upgraded as not directly required: numpy in c:\program files (x86)\python36-32\lib\site-packages (from vispy) (1.14.3)

[alexschn]

vispy.test()

I'm surprised... But the easiest way to fix it is to downgrade your matplotlib version.

[alexschn]

I am beginner in the python how can i downgrade matplotlib ? thank you for your help

[EtienneCmb]

Try to run: pip install matplotlib==2.1.0

[alexschn]

C:\Program Files (x86)\Python36-32\Scripts>python

from visbrain import topo
from visbrain import sleep

that what i get

[alexschn]

It is suppose to run the program ?

[EtienneCmb]

Which script did you try to run from your terminal?

[alexschn]

visbrain sleep

[alexschn]

I am sorry i just even dont know how it suppose to be. I need to analyze 24h recordings of eeg . rem and nrem

[EtienneCmb]

Ok, no problem.

There is a full documentation on the website for sleep data. There's also a set of examples. Those examples illustrate how to load sleep data.

In short :

• Open your notepad and create a *.py file (for example basic.py)
• Import Sleep and open the graphical user interface

from visbrain import Sleep

Sleep().show()

• Once your python file created, from your terminal run :

python basic.py
