OpenCL evaluator is attempting to initialize OpenCL

Hi Maya users. 

 

Could somebody attempt to explain what this means? I occasionally get crashes in Maya 2018.2, and my preferences automatically reset. It's becoming annoying. This is the message that appears in the output window. Are the crashes maybe related to graphics card?

Hi @Anonymous

 

This could be a gpu issue, what GPU are you using and what driver version is it?

Hi @Anonymous

 

Ok good.

 

The problem might be with Intel IGP or your on board graphics card.

 

To fix this, you can disable them in Device manager and then try launching Maya!

 

Let me know if anything changes!

Hi Sean,

 

Thanks for your reply. I've attached an image of my Device Manager. There doesn't seem to be any other graphics adapter present. I'm running a new Dell Precision Tower. 

 

In the bios I left the graphics port selection as "auto". 

 

Let me know if there's something else I should do.

 

Thanks, 

 

Craig.

Hi @Anonymous

 

Hmm this is tough. It looks like Maya's having trouble detecting your GPU.

 

While your driver version is our certified version, could you try updating the drivers and see if that solves it?

 

Also, do you have any 3rd party plug-ins or applications that may be messing with your GPU and causing this issue?

 

Finally, this might just be something corrupted in your prefs or files so if the above doesn't work you may want to perform a clean uninstall/reinstall of Maya.

 

Let me know how it goes!

OK thanks. I actually recently did a complete new re-install of Windows 10, to see if this would fix it. But it didn't, so I don't think re-installing Maya would help. I'm starting to believe that Quadro cards are not that good. I have a much cheaper card on my machine at home, an Nvidia GeForce GTX 750Ti with very little problems. 

 

Before I did the re-install of Windows I had the latest Nvidia Quadro M2000 drivers running, with probably even more crashes than now. 

 

If you could recommend the most stable graphics card for Maya 2018.2, using the "Evaluation mode: Parallel" in the animation settings, what would you chose. I'm usually just animating 2 low polygon characters at any time in any scene with no environment, so I probably don't need anything super powerfull, I just want stability. 

 

Thanks,

 

Craig

Also one last thing about 3rd party plugins, it is very possible that there could be an issue with the Mental Ray plugin, but I need it for the project we are working on. Could this be the issue, maybe?

You already gave the answer yourself. Let your "home" experience be your guide. Get a decent GTX 10xx or 9xx card.

 

Really, don't waste your money on Quadros. I know, this once was a standard for 3D stations and it still better performs than so-called "consumer" cards in certain situations, like with trillion-count wireframes, but this was at a time, when there were not many alternatives. Nowadays there is no need at all for an animator (as well as any other artist) to have super-duper-highend-scientific-double-precision-military-grade-durability graphic cards.

 

In relation to your crashes, we had crashes with heavy rigs on Quadro equipped machines in Maya 2017 (I don't remember the exact Quadro model), which were resolved by turning off GPU Override for Parallel evaluation. All other machines equipped with different GTX cards performed just nice (770, 970Ti, 1070, 1080). And so did my "home" pc which has a 750Ti. 🙂

Hi @Anonymous

 

Our certified driver for your GPU with 2018.2 is version 385.08.

 

As for your thoughts on mental ray, it could be the issue. I understand you need to work with Mental Ray but as a test could you unload mental ray plug-ins and see if the issue still occurs?

 

Also, did you do a clean reinstall of windows and reinstall Maya or did you do a soft reinstall so all your programs were still there?

I did a complete re-format of the hard disk and reinstalled Windows 10, and then Maya 2018.2. I'm running Mental Ray on my home machine also so I'm believing it's probably the Quadro card. I will get my studio to get me another cheaper card. Autodesk should either fix the problem they have with Nvidia or just tell people that you would not recommend Quadro cards for the latest releases of Maya. 

 

Thanks for your your help though. If the new card fixes the problems I'm having, I'll let you know.

Hey, thanks for telling us your experience with Quadros. I am now agreeing with you, Quadro cards don't seem to be that great after all. I'm quite sure all the problems I get is because of the card. I will try just using the evaluation mode DG, thanks! 

 

I think I remember reading somewhere that if you use rigs that were built in versions of Maya before 2017, they do not perform so well. Not sure how true this is, but could be something to do with the crashes also. Next project I think we will start fresh with rigs build in Maya 2019. 

 

Thanks!

Hello @sean.heasley 

 

I seem to be having the same issue with Maya 2018 no longer starting up, and with following message in the Output window:

OpenCL evaluator is attempting to initialize OpenCL.
OpenCL initialization has been disabled by user
00:00:00 663MB WARNING | node "MayaMultiplyDivide" is already installed
00:00:00 663MB WARNING | node "MayaClamp" is already installed
00:00:00 663MB WARNING | node "MayaGammaCorrect" is already installed
00:00:00 663MB WARNING | node "MayaCondition" is already installed
00:00:00 663MB WARNING | node "MayaReverse" is already installed

 

I've tried the following so far:

 

- Adding "MAYA_DISABLE_OPENCL=1" into the Maya.env file 

- Clean uninstall/reinstall of Maya 2018 

- rolling back to previous version of graphics driver

- updated latest version of graphics driver

-updated drivers for Wacom Cintiq which is being used as the main display 

 

Like Craigp I also don't have another driver listed to try disabling it in the device manager.

 

The GPU I'm using is GeForce GTX 1080. Version 451.48.

 

Thanks very much. 

 

J
