Plot freezes after few seconds and instantly on Jupyter #6

Closed joaoponte closed 4 years ago

joaoponte commented 5 years ago

I'm facing a problem with plotoptix in a Ubuntu 18.04 with CUDA 10.2, FFMPEG 4.2 and Mono 5.20.1 in my system and CUDA 10.1, FFMPEG 4.2 and pythonnet 2.4 in a conda environment.

All seems to work well running the code on a terminal, but after few seconds the plot freezes and I'm forced to kill the thread to close the window.

In Jupyterlab, for example, the plot window open but freezes almost immediately after opening.

Is there anything I'm doing wrong here? lol I did the Windows step on my personal laptop and all worked pretty amazingly ;)

Here is some information about the system and conda environment.

System:

Ubuntu 18.04

And freezes even without any interaction with the mouse. I removed a lot of dummy lines, but preserved the lines with two mouse interactions I did at that moment, but I tested without interaction and froze anyways.

Can you let me know your NVIDIA driver release?

joaoponte commented 5 years ago

Of course! The installed nvidia driver is the 430.26

robertsulej commented 5 years ago

OK, great. There is a good chance that changing the driver will solve the problem. You can either try the newest (435 or 436) or downgrade to 419 (Windows) or 418 (Linux). I experienced issues with 430 and OptiX' internal threads synchronization, and since it appears only on some system configurations, I could not solve this with NVIDIA guys.

joaoponte commented 5 years ago

Hey @robertsulej, sorry about the waiting time!

I tested with the 435.21 driver and I faced the same error.. The funny thing is that when I tried to install the 418 driver, the "Graphics Drivers" PPA pointed to the 430.50 driver, lol

Do you have another idea to test or other source of logs to send to you? Is it maybe the CUDA 10.1?

robertsulej commented 5 years ago

Oh, that's bad that 435 didn't work. I'll test it in Linux on the problematic system. I was happy to see that 436 worked well in Windows but did not look at 435+Linux.

The link to 418 is in the archive: https://www.nvidia.com/Download/driverResults.aspx/149219/en-us

CUDA is not referenced until you create video encoder, so the CUDA release number does not matter here. The freeze which I know happens in the OptiX core function, which never returns. I am travelling now, when I'm back I'll see how to confirm that that this is that problem.

joaoponte commented 5 years ago

Thanks for the link! I didn't test the 418 yet because it is a different process to update and I must require a authorization to do that (my pc is shared with others).. But I tested the 415 via PPA and didn't work as well.. I will focus on the 418 and later I send you the results!

I understand, so it is indeed in the nvidia-driver package.. Maybe a buffer that is overflowing, because it works really well during some seconds.. That is what makes everything kind of strange..

Ok, don't worry about that. Enjoy your travel and after that we continue trying to solve this

robertsulej commented 5 years ago

Just a quick comment: 418 is minimum required by OptiX 6. Part of OptiX code was moved to driver libraries and it won't work <418. Thanks for tests!

robertsulej commented 5 years ago

I've just uploaded v0.5.1 to PyPI. It should report timeout on the terminal and not freeze the window when stucked in the internal library function.

I also tested 435 in Linux. It works well on my machine which was problematic for 430.

I am also working on moving to OptiX 7 where things arranged differently and there is much less of black-boxed parts on the OptiX side. Hopefully this will work for everyone ;)

joaoponte commented 5 years ago

Thanks for the update! Unfortunately, the plot continues freezing after few secs.. Also, I didn't see any information on the terminal after freeze! I got only a line with "done", which already was before the update.

Maybe it is not an OptiX problem, but anything else.. I will try a clean env and test it again

joaoponte commented 5 years ago

Tested with a clean conda env and got the same result

I mentioned that It should give me some information and not freeze the window. It is interesting, because every time I test, I need to send a kill sign to close the thread, because neither the terminal window nor the render responds anymore.

Maybe it is a clue..

robertsulej commented 5 years ago

Default timeout is quite long, 30s. You can set it lower with optix.set_param(rt_timeout=x_millisec) called before optix.start(). Message "done" gets printed from another thread so it can arrive before timeout message.

Does it freeze on every example script?

joaoponte commented 5 years ago

Oh, this is really useful to know! But I waited way more than 30s and the message didn't come :/

I tested so far all terminal examples and some of the jupyter notebooks and all freezes without returning any error message.

Is there any other test you want to run or information that you want to know?

robertsulej commented 5 years ago

Thanks for all the tests you've done so far!

Until now I did not see a system where all of them are freezing... From your DEBUG output it looks like the OptiX library problem though. It may be difficult to debug at a distance. I'll try to find a way to pin the problem, but it might be that it won't get solved before moving to OptiX 7.

joaoponte commented 5 years ago

No problem, I really want to help to solve this ;) I see a huge potential on your lib! And thank you for all your support!

Indeed, It's definitely hard to debug these kind of problems at a distance.. I'll wait for the OptiX 7 implementation and, in the mean time, I will try to test my system with the OptiX 6 and 7 to find what happened.

MartinSmeyer commented 4 years ago

Same issue here after following install instructions on Ubuntu 18.04 with 435.21

robertsulej commented 4 years ago

The new release is out. Shader compilation changed and issues like this one should be gone. This was a significant rewrite, if new issues appear, please, let me know!

joaoponte commented 4 years ago

Thank you very much for the update!

I tested on my personal computer and all went well. However, in my problematic system, the update doesn't worked as well..

Same problem, the plot froze after some seconds and I needed to kill the process manually. I used a Ubuntu 18.04, NVIDIA drivers version 440.64 and CUDA 10.2.

In the terminal, the program outputs this: [0]: Titan X (Pascal) done

robertsulej commented 4 years ago

Tanks so much for testing!

Uh... that's not a best news... I'll investigate. Could you, please, try running with changed log level and post the output? The log level is a constructor parameter, like this:

rt = TkOptiX(log_level="DEBUG")

joaoponte commented 4 years ago

Of course!

Thanks! Compilation looks OK. Something else is locking the ray-tracing/refreshing loop. I'll search for the problem.

Just a small update ;) There is no urgency on this, since I use your software in my laptop. S it is all good.

I did the upgrade of all releases, including the new one - 0.8.1 - and the plot still freezes at the same point in my system with the Titan X (Pascal). With all updates in my system, the SO is the Ubuntu 18.04, driver version is 440.82 and CUDA version is 10.2.

With my (g)old 980M (NVIDIA driver version 446.14 and CUDA 10.2) in my laptop, everything works fine.

Hi Joao, Sorry for no progress! Still can't find a system where I could reproduce this freeze and chase the bug. Uh....

joaoponte commented 4 years ago

Hi Robert, There is actually no problem at all This is a strange bug and I'm just a beginner in C/C++ to even try to solve this, lol

joaoponte commented 4 years ago

Hi Robert!

Sorry for the delay to test the new releases. I lost the connection to my computer in my lab for all these months, but now I went back to normal!

I think that since 0.8.2 the render worked well, but I'm sure that 0.9 works without any problem! So I think that this issue is now solved ;)

Thank you very much!

Thats great to hear, thanks! There were many low-level changes and a switch to OptiX 7.1, hope we have this freezing sorted out.
