Spyder can't start because of problems with OpenGL and PyQt5

I get this code:

Untill I make Ctrl+C, then I get the UI.

Questions:

1. Are you using Qt5?
2. Do you have an Nvidia card?

[abdelouahabb]

Yes, Qt5 because Python 3.5 (cant install pyside),
And yes, Nvidia 525M

[ccordoba12]

Then this is a problem either with Qt5 or your Nvidia drivers. Someone else reported before a similar problem on Linux in issue #3226. The solution was for him to switch to use his Intel card.

Unfortunately, we can't do anything to help you with this, sorry :-/

[abdelouahabb]

that's ok :( waiting for pyside for python 3.5x 👍

[ccordoba12]

Ehhh, we don't officially support PySide anymore. I mean, Spyder 3.0 can
work with PySide, but there are several outstanding bugs with it, and we
expect help from the community to solve them :-)

I hate nvidia -_- I switched to Python 3.5x to use async - await feature, and he I am with bugs :(
... keeping 2.7.11 to use with spyder !

[patstew]

Have you got an optimus laptop? Have you actually got both the nvidia and intel drivers installed? The proper one from the intel/nvidia website? It looks like it can't find opengl, which both of those drivers ought to provide. If you have an optimus laptop (likely with a 525M), try forcing it to run on the nvidia card instead (it will run on intel by default). If all else fails, you can get the opengl software renderer here http://download.qt.io/development_releases/prebuilt/llvmpipe/windows/ - stick opengl32sw.dll in your python directory and enjoy the slideshow :).

[abdelouahabb]

WORKED! but only after bringing the opengl32sw.dll into the directory, even forcing python to use nvidia, it dident work, it needs the dll ! Thank you again!

[xxblx]

@abdelouahabb can you test thoose actions #3226 (comment) with clean spyder3 without any external dlls?

Adding

from OpenGL import GL

into site-packages/spyder/app/start.py solves problem for me in GNU/Linux (Fedora 24 x86_64, Nvidia GT 240).

Test please same actions in Windows.

[jondo]

Under WinPython on Windows 7, I have fixed a similar problem by getting libEGL.dll and libGLESv2.dll from the Qt5.7 release, and updating DirectX, see the Details.

[ccordoba12]

@rlaverde, please work on this one. The idea to solve this is

1. Add pyopengl as a dependency, but only to setup.py (we're not going to add it for conda packages).
2. Don't add it to our README or anywhere else to not cause confusion between conda and pip users.
3. Add the lines mentioned in this [Linux] Segmentation fault on start because of problems with OpenGL on Intel cards #4495 (comment) to our app/start.py file, but inside a try/except to avoid a failure for conda's Spyder.
