Topo Error #18

Closed STREETKILLER007 closed 6 years ago

STREETKILLER007 commented 6 years ago

hello, developers, i am new in python.

i am trying to run this code in python.

111

but the error that i got is

112

after i read through the comment, i tried to install visbrain in developer mode and tried to run pip install matplotlib == 2.1.0 but it pops out this error 113

i tried to update my setuptools using pip install --upgrade setuptools but it did not solve my problem.

is there any suggestion to solve this error ?

thank you.

STREETKILLER007 commented 6 years ago

tried this example https://github.com/vispy/vispy/blob/master/examples/basics/gloo/display_lines.py under Visbrain.

It pops out this error.

What do you mean "I tried this example [...] under visbrain"? I thought vipy was working? You still have the same backend issue. If you're still stuck with visbrain, I know that mne-python can also plot topo plot. See this for example

STREETKILLER007 commented 6 years ago

"I tried this example [...] under visbrain" mean that i tried https://github.com/vispy/vispy/blob/master/examples/basics/gloo/display_lines.py after i installed Visbrain.

Update

i created another environment, which is also Python 3.6.

after i typed conda install "pyqt<5"

what i did was below :

1) before install Visbrain

before install

2) after install Visbrain after visbrain

It Seem that Vispy is working fine.

===

After that, i tried to run following :

1) testtopo.py

the code is

from visbrain import Topo

# Create a topoplot instance :
t = Topo()

if ignore the vispy error, it seems fine.

capture

2) testtopofull.py

the code is

from visbrain import Topo

# Create a topoplot instance :
t = Topo()

# Create a list of channels, data, title and colorbar label :
name = 'Topo_1'
channels = ['C3', 'C4', 'Cz', 'Fz', 'Pz']
data = [10, 20, 30, 10, 10]
title = 'Basic topoplot illustration'
cblabel = 'Colorbar label'

# Add a central topoplot :
t.add_topoplot(name, data, channels=channels, title=title, cblabel=cblabel)

# Show the window :
t.show()

testtopofull

Hi @STREETKILLER007 ,

Here's some ideas :

I'm not sure to understand what the conda install "pyqt<5" does because in your first pip list I can't see PyQt4 / 5 installed. But, at least on my computer, I remember I had issues with he PyQt5 installed using conda and I had to remove it and use pip.

I can show you the steps used to configure from scratch the environnement using conda :

STREETKILLER007 commented 6 years ago

according to @ djhoese, conda install "pyqt<5" is to check whether vispy is working properly or not.

I did not look at MNE-Python, because i would like to try out Visbrain.

i will try pip install pandas PyOpenGL

after install PyOpenGL in my environment, below is my pip list

when i tried this commend

from visbrain.objects import BrainObj
BrainObj('B1').preview()

it pops out this error

EtienneCmb commented 6 years ago

Ok, if the GUI is displayed this mean that both vispy and PyQt5 are properly installed.

May be dhoese (vispy) was right, you might have a driver issue... Can you try to install PyOpenGL as mentioned earlier?

Ok... Well, hence it might be a driver issue...

STREETKILLER007 commented 6 years ago

I tried to update all my driver. my graphic card is already up to date...

EtienneCmb commented 6 years ago

BTW, for topoplots the ScoT toolbox is also able to do it. Just in case

STREETKILLER007 commented 6 years ago

Will look at ScoT toolbox, thank you.

Nice, it works :)

Can I close the issue?

STREETKILLER007 commented 6 years ago

Leave it open first since i will be trying to work on my pc...

STREETKILLER007 commented 6 years ago

@EtienneCmb To run Visbrain, except graphic card and processor, would like to know that what else should i consider on running Visbrain in a computer ? Let said i am using Windows.

EtienneCmb commented 6 years ago

Well, RAM is also useful :)

But yeah, not so much because I've a very old computer and it works just fine. I've also installed Visbrain at least on 10 systems including OSx, Windows and several Linux versions and never had a big issue (except yours...). On the visbrain's chat, there's also many users that finally got it works

STREETKILLER007 commented 6 years ago

Below is my spec :

1) processor Intel(R) Pentium(R) CPU B980 @ 2.40GHz

2) graphic card Intel(R) HD Graphics

3) ram 10gb, ddr 3
