Stuck on PrepareDenseScene

[ROllie84]

I'm very new to this and am constantly finding a completed orange bar over PrepareDenseScene node and the log I have shows its completed but doesn't proceed to CameraConnection. I'm only using 29 images and the log below is as follows:

Program called with the following parameters:

• input = "S:/3DSMFiles/Rudys3dhead/CompiledHead/MeshroomCache/StructureFromMotion/4783bbb0448dbfb5e286a00b80956525fb68c7ef/sfm.abc"
• output = "S:/3DSMFiles/Rudys3dhead/CompiledHead/MeshroomCache/PrepareDenseScene/d548193ad52d968d9f2ef105ce8ed8d3ef9a3f0d"
• verboseLevel = "info"

I'm on a windows 7 system. Any help would be appreciated.

Meshroom on Win7 is known to have some problems #216 #183 #145.
Try again with a sample dataset that is known to work and report back: https://github.com/alicevision/dataset_monstree/tree/master/mini6

Tested out with the images provided in the link. I get approximately 50% DepthMap before an error message:

[15:51:19.629176][info]
[15:51:19.635176][error] This program needs a CUDA-Enabled GPU (with at least compute capablility 2.0).

The last line doesn't make sense as I have a GeForce GTX 750 with a CUDA-Enabled GPU of 5.0 compute capability. Unless they want a capablility which I hope is just an error in spelling and not some new computer jargon.

I hope I am missing something and any help would be appreciated.

@ROllie84 Install the latest Nvidia driver for your GTX 750. Sometimes the driver is not up to date, a wrong driver version for your GPU or not installed at all.
If it still does not work, I am pretty sure this is a Win7 related bug #216 #183 #145

[ROllie84]

Thanks @natowi
I've verified my driver settings are up to date. I have re-run the process. This is the latest log report.

Could you try with the patched version for Windows 7, available here, and close this issue if this solves your problem ?
Thanks!

[Cheboy]

Im also new to this and Im using Win10. Having the same issue as the mate here describes. Dont know how to go any further. In my case Im using 119 pic. and I have a geforce 940mx. Not a powerful gpu but I did get some good results with the sample fotos of the rock that someone in github provided.
Im open to suggestions.
