Python and Java API / Re: Freezing while computing the “loading photos” step of buildDepthMaps

« on: June 03, 2020, 11:51:39 AM »

Hello Alexey,

unfortunately the problem with the freeze still occurs in the process step generating depth maps (loading photos) from time to time. We tried a few things and ran the script with and without GPU. Both times the system crashed. Then we computed the point cloud with the XML batch process and it ran without any problems.
Here the configuration of our system where the error occurs:

Code: [Select]

2020-06-02 08:55:49 Agisoft Metashape Professional Version: 1.5.5 build 9097 (64 bit)

We have also tested with versions 1.5 and 1.6 and with other hardware. The error occurred with both versions, but not on a different computer with the following configuration:

Can you give us any indication why we can process this specific step (generating depth maps) with the script on one computer and not on our workstations? Can it really be a hardware issue? I attached the log from the last run which failed as usual with loading photos. I am grateful for any advice.

Best,

Thanks a lot Alexey, updating the GPU drivers seems to be the solution.

Hello Alexey,

my computer is equipped with 3 NVIDA Quadro P5000 and these run with driver version 431.86 (driver typ: standard)

Here is the log file of my last attempt. The process runs until it stops at step "loading photos". In the log this step is not written anymore.
When I run the script via Tools > Run Script... are the preferences set via the GUI used or a default?

Hello Alexey,

thanks for the quick response. I did not use the gpu_mask command and I did not make any other GPU configuration in the script. Should I do that?

Here is a photo of the last log entries. I will write a log file next time.

Best,

Python and Java API / Freezing while computing the “loading photos” step of buildDepthMaps

« on: April 07, 2020, 07:16:40 PM »

Hello,
I’m using the Metashape API in version 1.6 for large batch processes. Since last week my PC completely hangs off (freezes) while computing the “loading photos” step of buildDepthMaps. The problem occurs independently of the number of processed images and just in the script execution. If I start the workflow manually in the GUI, there aren’t any problems.

Code: [Select]

chunk.buildDepthMaps(downscale = 4,
                     filter_mode=Metashape.ModerateFiltering,
                     reuse_depth = False)
chunk.buildDenseCloud(point_colors = True)
I’m very grateful for any advice or shared experience to handle this problem.

Best,
Arnt
