[Anonymous]

Hi Maya Team,

We are getting these errors in Maya when Maya 2018.2 is launching.

import mtoa
// Successfully imported python module 'mtoa'

Do you know what could it be?

Thank you very much for your time.

Hi @Anonymous and welcome to the community!

It looks like the errors are pointing to Arnold.

Are these errors stopping you from launching Maya or do they just appear as you launch?

If you can open Maya, you can try unloading the Arnold plug-in and re-loading it.

Let me know if anything changes!

Hi Sean,

the errors appear only when you launch Maya without breaks.

Hi @Anonymous

In that case, please try unloading and reloading the Arnold mtoa plug-in.

If that doesn't work, you can also try deleting your settings/preferences.

[Anonymous]

Unfortunately it is not mtoa plugin.

Hi @Anonymous

Ok, have you tried resetting your settings/preferences?

[Anonymous]

they are default. I have just installed Maya.

[sean.heasley]

Hi @Anonymous

Hmm ok.

You may want to make sure you have installed the most recent version of Arnold which can be found here!

Also, what GPU are you using and are the drivers the same as our certified hardware requirements?

You can find our certified hardware list here!

I tried to turn off all plugins. So it does one of the default plugin from
Maya.

it seems that the newest Nvidia driver for quadros has solved that problem.

We will do more tests on the PCs...

Thank you very much for your help.

Hi @Anonymous

Great! I went ahead and marked this as a solution but if the problem occurs again please let me know and we can troubleshoot further!

[Anonymous]

Yes, no problem. 😊

[Anonymous]

hmm... so unfortunately it didn't help to fix that issue. 😞

[sean.heasley]

Hi @Anonymous

So what happened? Did it work at first then stop working?

Also, when you uninstalled and reinstalled, did you perform a clean uninstall/reinstall of Maya?

[Anonymous]

yes, it is strange. once it's with error and once is not. 😕

I don't understand why.

Yes, the installations were fine.

[sean.heasley]

Hi @Anonymous

Ok, can you try uninstalling Arnold completely?

Steps to do so can be found here!

• Remove the old version by finding the MtoA group in the Windows Start menu, and selecting Uninstall, or
• Locate the Uninstall.exe file in the folder where you installed the previous version of MtoA to, and execute that yourself, or
• Use the Add/Remove programs function in Windows.

Hi Sean,

could you please give me the right path to the uninstall software - arnold? We could not find it. 😞

Thanks

[Anonymous]

Hi Sean,

unfortunately we still have some issues in with that error. We uninstalled Arnold and it is still there.

What to do next?

Thanks

[sean.heasley]

Hi @Anonymous

Hmm ok.

What are the pc specs of your machine?

Steps to find your pc specs can be found here!

Also, you said the install went fine, but did you perform a clean uninstall/reinstall of Maya?

Finally, could you try installing an older version of Maya like 2017 and see if the same issue occurs?

Here is a screenshot.

If you want more details, then where should I send them?

Thank you.
