Can not load Arnold module in maya 2018 (any phython issue?)

[prur]

Newly installed maya 2018 doesn't load Arnold properly. I've tried several different version of MtoA but no luck. Below is the log after I reinstalled MtoA 3.1.1.

One thing I noticed there is always Python engaged error comes up. As my computer had python installed before Maya, I reckon those are somehow conflicting each other.

I couldn't find any similar issues on the net. Please help me.

The cannot import name _unicode error may or may not be related to the problem loading MtoA.

What happens when you run this Python in the script editor?

import arnold

Maya bundles Python in the Maya install, so you shouldn't be getting that _unicode error.

Run this in the script editor:

import genericpath
from genericpath import *
from genericpath import _unicode

Check the environment in Maya For example, does the PATH include any older versions of MtoA? If you're on Windows, run the MEL command system("set") to get the environment.

Hi @Stephen Blair,

When I run <import arnold> nothing happens. No response.

And second script comes up below error.

import genericpath
from genericpath import *
from genericpath import _unicode


# Error: ImportError: file <maya console> line 4: cannot import name _unicode # 

My system("set")

system("set");

Can you notice what is problem? thanks for the help

[Stephen.Blair]

I would remove C:\Python27\Lib from PYTHONPATH

Then, if you still have problems, turn off autoload fro Mtoa, restart maya, and run Process Monitor when you try to import _unicode
