Failure at ...hierarchical_stereo.cpp

[lefsky]

When building dense could, I get the following error multiple times:

Error: Failure at C:\Users\buildserver\buildbot\slave\win64\build\sources\libs\libstereo\gpu\hierarchical_stereo.cpp:161

Tried reinstalling driver but the error persists.

This error started appearing about a month ago and looks to me like either a hardware problem or one introduced by a windows update.

Has anyone else seen this problem?

Hello lefsky,

Can you please provide more detailed log, starting from the beginning of the processing stage (where the task parameters are specified) and also the copy of the Console pane starting lines that are shown right after the application is started.

Additionally please specify the OS version, Metashape/PhotoScan version, GPU model and GPU driver version.

[lefsky]

I am using  1.5.0 build 7336 on Windows 10. My GPU is NVIDIA GeForct GTX 780 Ti with driver version 24.21.13.9924. Windows reports that it is the most up to date version

I've attached the log file. Here is the output of the build dense cloud command:

Hello lefsky,

I can suggest to update to Metashape 1.5.2 and also check for the latest drivers on NVIDIA web-site:
https://www.nvidia.com/Download/driverResults.aspx/145872/en-us

However, the issues that you are observing seem to be related to insufficient VRAM on some stage and in such case the processing is performed on CPU. Do you have any other applications running in parallel, that utilize GPU intensively? Also is that correct, that you are processing only a few images, but of the large resolution (probably scanned historic aerial images)?

Hi lefsky,
having the same error here on ubuntu 16.04, but in line 171
unfortunately nothing helped for me, drivers update/check, change of OS (Windows, that I don't love, but same behaviour on the very same operations as linux ones)
probably is due to some memory card allocation issues, mine was GTX 1050
switched to GTX 1070 8GB and solved the situation, being in a hurry and in need to respect my incoming timeline
sorry but not solving anything, only feeding more memory to the hungry beast
best,
f.

Got the same Problem here:
"Error: Failure at hierarchical_stereo.cpp:165".
Metashape Version 1.6.3 b10732 x64
Images are 150 Megapixel 8Bit per Channel JPEGs (5005x11814x1216 disparity using 1001x985x8u tiles).
Card is a RTX 2080 SUPER

Hello cschreiner,

Which NVIDIA driver version you have installed?

[Dannosuke]

I'm having the same issue metashape says there is 0 VRAM, but the VRAM utilization is only at 18% of 8GB

My console readout is below. I have a threadripper 1920x so it's still going relatively fast on CPU anyway.

Hello Dannosuke,

Which OS version you are using and which AMD driver version is installed?

[Dannosuke]

I'm on the latest Windows 10 Pro 20H2 and the 20.12.1 AMD Drivers. I just updated to the latest drivers I'll let you know if the problem persists.
