Oh, this does not look nice. Does anybody have experience with Mayavi on Windows? Eric? ---

Is this on Windows? That looks like a Unix directory structure to me. In any case, it looks like a bug with Anaconda to me. It will probably be tough to debug. If you can make an mne-python issue, we can try to isolate it to some minimal example that only uses Mayavi. Then the Anaconda folks can fix it hopefully. In the meantime, do you know if your packages are up to date? You can normally do e.g. `conda update mayavi` but it looks like you're on a site install, so you'll have to ask your IT folks (and maybe see if they can replicate it, too). Eric ---

My bad, Eric, it's Linux. ---

Hi, This is on Linux. Sure, should I post the error on github? I'm quite new to python so I don't know how to check if my packages are up to date. I'm using the python package installed on the cluster at the Martinos center. I'll check with the IT folks, thanks! Best, Gladia ---

Yeah go ahead and make an issue, we'll try to isolate the problem there. Eric
