meshroom not detecting GPU - please help

[shorty j]

I get this error on depthmap every time no matter what I try.  I've tried reinstalling/updating drivers, setting meshroom.exe to use all GPUs in NVIDIA control.  I'm sure i've tried several other things I've seen on forums too but no luck.

[14:08:48.496508][warning] Could not determine number of CUDA cards in this system

Cuda device query yields the following.  Please help?

I had the same problem so contacted NVIDIA. They were very helpful, told me the correct driver and CUDA version combo I needed for my setup. I can no run Meshroom no problem.

I was given the latest on both versions for my card by NVIDIA support - but it hasn't seemed to help...  It's very frustrating.   Any suggestions?

[Steven Lancaster]

Sorry to hear that. All I can do is let you know the steps I went through on Windows 10, which were :

1. Install Microsoft Visual Studio

2. On advice from NVIDIA, installed latest driver for my GPU, and best version of CUDA that my GPU can support (in my case not the latest version of CUDA)

3. In Windows Graphics options, set the processor to High Performance for Meshroom, i.e. my GPU not the CPU

4. As my laptop only has 16Gb RAM, I needed to reduce the DepthMap resolution, by increasing the Downscale parameter to 4 in the DepthMap node.

Good luck

I'll try those steps tonight along with fresh installs of all drivers.  Thank you!   Was there a minimal installation of Visual Studio that was required?  I think I did most basic setup when I ran that.
