lbm_ldc.py throws OpenGL.arrays.arraydatatype

[Aritra Nath]

Hi Michal,

Sure enough :

1. When I try to run the example lbm_ldc.py I see this error:

C:\Simulation\sailfish>python C:\Simulation\sailfish\lbm_ldc.py

cuInit

cuDeviceGetCount

cuDeviceGet

cuCtxCreate

cuCtxGetDevice

No handlers could be found for logger "OpenGL.arrays.arraydatatype"

Using the "cuda" backend.

[0000.10] Initializing visualization engine.

Traceback (most recent call last):

  File "C:\Simulation\sailfish\lbm_ldc.py", line 72, in <module>

    sim.run()

  File "sailfish\lbm.py", line 912, in run

    self._init_vis()

  File "sailfish\lbm.py", line 359, in _init_vis

    if self.grid.dim in engines[self.options.vis].dims:

KeyError: 'pygame'

cuCtxPopCurrent

I am not sure if the problem is with PyopenGL because it is the one that is compiled with Python2.6 and that is wht each package has been compiled with.

Aritra

Hi,

AFAIR, there have been reports of successful Sailfish installations on
Windows.  This will however almost certainly be _more_ difficult than
a Ubuntu installation, so my advice would be to try to spend some more
time on getting CUDA working on Ubuntu.

Hi,

I looks like the problem is actually with the 'pygame' module. You
might be able to run the simulation in batch mode (--batch) without
any on-line visualization.

Hi Michal,

I see what you say. I added a print statement between line 358 and 359 in the lbm.py see in bold the message :

Aritra {'mayavi': <class 'sailfish.vis3d.Fluid3DVis'>, 'surface': <class 'sailfi

I believe the pygame should also be there but it doesn't show up there.

Any suggestions?

Hi Aritra,

I believe the pygame module fails to load for some reason. Try
starting an interactive Python shell and running "import pygame".

It's a very old post, but this is one of the top results on google for this problem, and the correct solution doesn't seem to be posted, so I might chime in. Installing numpy fixed this for me, it was listed as one of the "recommended" modules, however for the install instructions for Python 2.x it is actually listed as a dependency.
