PyQt5 passes checks but simulator still crashes #71

Closed espinielli closed 7 years ago

espinielli commented 7 years ago

I installed as per instructions. I run the checks and then the applications, got a brief dialog with some QEGLPlatformContext: eglError 3005 ... error message than the application crashed. Here is the output:

Hi Enrico,

There are known GL issues with Intel integrated graphics for 3rd generation core-i processors and earlier. Could this cause your problem, or do you have a different h/w configuration?

espinielli commented 7 years ago

With latest commits now I get something showing up: image

If I aknowledge the first warning, I get a second one:

QEGLPlatformContext::init: eglError: 3005, this: 0x8fa0ab0

Acknowledging that, and loading a scenario keeps the screen white...

jooste commented 7 years ago

What platform are you running this on? From what I can find, QEGL* is related to OpenGL ES (Embedded Systems), which is specific to devices like smartphones.

espinielli commented 7 years ago

System Model HP EliteBook 840 G1 Processor Intel(R) Core(TM) i5-4300U CPU @ 1.90GHz, 2501 Mhz, 2 Core(s), 4 Logical Processor(s)

No way to get Graphics Card info, no sys admin rights...such is Corporate IT, sigh. Probably used the default things, such as in this brcohure

jooste commented 7 years ago

Ok, you have a 4th generation core-i processor, so even with the integrated graphics BlueSky should work. I am wondering, though, about the OpenGL ES thing. Have you used your current python installation for mobile/tablet development or anything like that? I get the impression that a library is loaded that shouldn't be there.

espinielli commented 7 years ago

No this is on my laptop at work...no mobile/tablet...

jooste commented 7 years ago

A way to test whether something in your python distribution is causing this is to try a bundled Bluesky release, e.g., https://github.com/ProfHoekstra/bluesky/releases/tag/20161201. This release isn't up to date with the latest commits, but if it starts this might tell us a bit more.

jooste commented 7 years ago

Oh, according to the specs brochure your laptop should even have discrete AMD graphics. The GL version of BlueSky should definitely work on your laptop.

espinielli commented 7 years ago

Anything I should check? Traces to be enabled somewhere? (The Qt-based version is certainly prettier)

jooste commented 7 years ago

Well, have you tried installing the bundled version? It comes with its own python and its own libraries. If it gives the exact same problems we have to look elsewhere, but the fact that you get a OpenGL-ES error makes me think that its related to the libs.

espinielli commented 7 years ago

I installed following the instractions...for a colleague of mine: we get the same errors. My machine is wilder, but strangely I have the same errors as a from scratch install.

Did you use the python-xy or anaconda bundle, or did you install python manually? I vaguely remember that Qt5 can give problems on windows (works perfectly on mac and linux though). The bundled bluesky installer has a known good combination of libraries, which makes it a good check. You can just uninstall it afterwards. Alternatively you can try to replace pyqt5 with pyqt4, or switch to anaconda/python-xy if you installed your current python manually (of these two bundles, anaconda seems the most active one).

I cannot really think of anything else. When I google for the error code I just get android stuff. Its also just weird that a regular windows installation of python + libs gives you OpenGL ES. This is another benefit of the python bundles (python-xy and anaconda): there at least you know that the libraries are suitable for your platform.

espinielli commented 7 years ago

No bundle...I have a 2.7 version coming from ArcGIS, then followed the instructions on the wiki. On the contrary on OSX I am out of luck with it: tried everything and failed. I'll try your suggestion at work on Windows and give a try w/ Anaconda on my mac at home.

jooste commented 7 years ago

Based on this I think that the first item on the list for revision of the docs on the wiki are the installation instructions! These are the configurations we use most at the moment:

windows: 64-bit Anaconda with pyqt4 and pyopengl >= 3.1.1a1 macos: 64-bit Anaconda with pyqt5 and pyopengl >= 3.1.1a1

espinielli commented 7 years ago

I tried on osx 10.11.6 in a pyenv with python 2.7 and all prereqs, the miniconda instructions failed miserable at PyQt5. I did not find a way to install it.

Could please you post a gist with the exact sequence of commands? Or did you consider building a docker image for bluesky? I really appreciate any help you can provide.

jooste commented 7 years ago

Indeed. I will make detailed installation instructions for mac and windows. A docker image also sounds like a good idea, I'll look into that!

jooste commented 7 years ago

Hi Enrico,

I've updated the installation instructions on the wiki. I've validated them on a windows and a Mac system. Let me know if it also works for you, or if you have other comments!

espinielli commented 7 years ago

No luck. Here is what I did:

  1. Set anaconda up pyenv install anaconda2-4.2.0

  2. Install pyopengl-accelerate as per installation instructions: conda install pyopengl-accelerate It failed as follows:

    but this was a problem of umask, so I changed mkl-2017.0.1-0.tar.bz2.part and the default umask to 002 and was able to finish installation.

It looks like I have to explicitly install pyqt...did you install it explicitly?

jooste commented 7 years ago

I am not familiar with pyenv, but my guess is that it only installs the bare minimum, as installing pyopengl also still required things like numpy. When you install the full Anaconda bundle you also get pyqt 5.6.0. Lets see if the following gets you all the required packages:

conda install pyqt=5.6.0 scipy matplotlib

In the meantime I did conda install pyqt
