Meshroom: [question] DepthMap crash

[xjoscx]

My DepthMap alway crash, and i do not know why.
Already installed a new driver for my geforce because the log showed issues with the geforce.
But it is still crashing.
Tested it with this : https://www.agisoft.com/downloads/sample-data/ today.

Your computer has 4GB ram? You need to reduce the quality of your reconstruction.

[xjoscx]

Thank you for your answer.

[xjoscx]

I just checked and technically my computer has 8GB ram.

[natowi]

Depending on your images this might not be enough. Image datasets with ~80 images can consume up to 20GB Ram with the default values. So you need to use the downscale parameter as described in the wiki. Also https://github.com/alicevision/meshroom/wiki/Reconstruction-parameters

[xjoscx]

So the downscale of DepthMap did not work for me.
Would it work if I use less images?

[xjoscx]

I found the Problem, install a different driver for my geforce and now it is working again.
