Bug Reports / Re: Generating texture or exporting OBJ causes PhotoScan to segfault?

« on: October 11, 2017, 01:47:04 PM »

Hi Alexey,

I do not have super-hard numbers on the memory consumption but I did see PhotoScan using 27 gigabytes of memory for a 200-photo project, which feels a bit on the high side. It could very well be the console pane content, because the memory consumption creeps upwards slowly during the whole process, which would be consistent with logging millions and millions of lines of text... I have now tried running a few multi-hour test runs (ranging from 50ish to a few hundred photos) both without supplying the progress callback, and supplying one that logs less often. In both tested versions (1.3.3 and 1.3.4), it seems like this did the trick. In other words: with the changes to the progress callback outlined in the previous post, PhotoScan does no longer crash. That little callback with a single print statement was the last thing we suspected, ironically!

We are using the PSX format. I did not record the peak memory consumption for either run, and remember only the 27-gigabyte number above. I do know that there was no swap usage, though, and the machines we used had 60 gigs of memory. I am not sure about the number of polygons or the texture atlas size, but the models should be fairly small. I am seeing numbers like:

Code: [Select]

(one project)
constructed triangulation from 70788 vertices, 141570 faces
 1789061 points 3577673 faces done in 25.6196 sec

(another project)
constructed triangulation from 204609 vertices, 409212 faces
 6733274 points 13466003 faces done in 102.692 sec

You mention version 1.4. How far along is that and how does the release schedule look? Will we see more preview builds before the stable release, do you think?

In following up on the progress callback mentioned above, we definitely do see it called *very* often. For a call to "exportModel" as an OBJ, an operation that takes on the order of 0.1 seconds when invoked without the progress callback in PhotoScan 1.3.3, the progress callback was called about 19340 times. The elapsed time is close to 2 seconds (as outlined in post #2). I tried this on PhotoScan 1.3.3, since there appears to be some further difference in 1.3.4 (as outlined in post #2).

Some further findings about the progress callback:

— buildTexture made 9300 calls to the progress callback (operation w/o callback takes a second or so)
— exportModel for the OBJ made 19340 calls to the progress callback (operation w/o callback takes less than 0.1 seconds)
— exportModel for the DXF made 1200 calls

As mentioned in post #4, the progress callback seems to significantly slow down operations. In our case, we log a progress update (using print) on each call. That could be a particularly expensive operation if it causes I/O to the log file. As an experiment, I expanded the status callback a little bit to only log at most once every ten seconds.

With that change, the time taken is within ±50% of when not supplying the callback, but we are experimenting with extremely tiny models so it is hard to say with more certainty than that.

This is the callback we are using:

Code: [Select]

def status_update(op_name):
    def inner(progress_pct):
        now = time.time()
        if now - globalz.last_status_update < STATUS_UPDATE_INTERVAL: return
        globalz.last_status_update = now
        print('%~ progress {} {} ~%'.format(op_name, progress_pct))

    return inner

We call it like this:

Code: [Select]

chunk.buildUV(
  mapping=PhotoScan.AdaptiveOrthophotoMapping,
  progress=status_update('buildUV')
)
Currently running some multi-hour tests on larger projects that were previously crashing consistently when supplying the callback – I have simply removed it for now. I do notice that PhotoScan uses a surprising amount of memory when exporting models from mid-sized (hundreds of photos) projects. This could potentially be because of the logging from the progress callback: the log files end up being many millions of lines and hundreds of megs of text – could the segmentation fault be related to filling up the console buffer? If I have time today I also want to run the same multi-hour tests again, but with the progress callback above that logs, but not as often.

Bug Reports / Re: PS 1.3 FREEZING !

« on: May 02, 2017, 05:39:20 AM »

Hi Alexey,

This time it seems to have gotten stuck at about 70.56%; it is always the call to "matchPhotos" that seems to hang.

Abbreviated output of ps:
PID %CPU %MEM    VSZ   RSS TTY STAT START   TIME COMMAND
 62  0.0  0.0   4496   744 ?   Ss   May01   0:00 /bin/sh ./photoscan.sh --gui -r /path/to/script.py /data

While writing this post, the PhotoScan process has consumed another two seconds of CPU time, so there is something happening inside. The UI is frozen though – can't click anything. This machine does not have any GPU(s).

We call matchPhotos with accuracy=PhotoScan.Accuracy.HighestAccuracy and preselection=PhotoScan.Preselection.ReferencePreselection.

Bug Reports / Re: PS 1.3 FREEZING !

« on: May 01, 2017, 01:14:04 AM »

Hi Alexey, I am sorry for the late reply. I saw a bunch of these problems about two weeks back, but fortunately it hasn't happened again. It seems to be random and quite rare. In the instances when it did happen, killing the process and restarting the exact same (scripted) processing worked – the problem did not happen again. If it does happen again, I will post in this same thread and try to give you as much information as possible.

Bug Reports / Re: PS 1.3 FREEZING !

« on: April 24, 2017, 05:09:30 AM »

We are experiencing similar problems using 1.3.1 build 4030. When running chunk.matchPhotos (on a machine without GPUs), PhotoScan hangs. Looking at top, it still uses a tiny bit of CPU – a hundredth of a second every here and there. However, it does not respond to any input: clicking pause or cancel doesn't do anything. We are calling matchPhotos with the progress callback and in one instance, the last callback happened at 32.34563770680988%, but it seems random where it hangs. There is more than enough memory for PhotoScan, and the project is very small (56 photos).
