Not enough memory on GPU
« on: August 31, 2021, 07:14:54 PM »
I want to texture and/or building tiled modell.

I always have this message in my console:


Estimated required video memory: XXXXX MB
Estimated device memory: total 4043 MB, used 65 MB, available 3437 MB
Cannot use GPU. Reason: Not enough memory on device


I always thought that metashape divides the model  according to the GPU?

Tested with GTX 1060 and GTX 970, my nvidia driver is 471.68 working on Metashabe 17.4

What can I do to calculate textures on the GPU?

Thanks

I was having a similar problem on my old Mac Pro earlier this year, and when I contacted Agisoft they sent me this:

-----------

Please try to create the BuildDepthMaps/pm_ooc_ref_tile_size tweak via Advanced preferences tab and set its value to 512 (default is 2048),

-----------

That mostly fixed the issue for me.

Thank you for the reply, but there is no change with this parameter.

Alexey, can you help me??

Hello Dieter,

Can you provide longer part of the log which comes before the not enough memory message?

Also specify the tiled model reconstruction parameters and number/resolution of the images in the project.
Best regards,

As you can see: sometimes it works, sometimes not....

The settings were as follows:
Tiled Model:
7004 cameras with 20 mpix
pixel size 0.002!!  (This is a requirement of the client)
tile size 1024
Source: Mesh
Face count: medium
Ghosting filter: on

With both GPUs (GTX1060 or GTX970), it looks like Metashape is calculating the GPU's free memory too generously. A tilesize of 512 did not bring any improvement either. Sometimes the creation of the model runs up to 60% only on the GPU, then the memory is calculated incorrectly and it is only CPU, which is slower by a factor of 10 for me. I have also already done tests only with the GTX 1060, because the memory is larger, no improvement...

Then I tried not to connect a monitor to the GPU with which it is calculated, so that no memory is consumed, no improvement.

What can i do?

Hello Dieter,

Have you already checked, if the texturing works on GPU without any CPU fallbacks, if you use tile size = 256 (default)?

I will do that tonight, what is the exact meaning of tile size?

I have now bought an RTX3060 with 12GB of RAM and replaced the GTX 970, now everything is running as it should.
Obviously, Metashape incorrectly calculates the memory of the GTX970 with 4 GB of RAM.
