numpy error when running mne.viz.plot_source_estimates

Hi,

I'm trying to visualize source estimates on my Windows laptop. I have
followed the installation instructions on the MNE webpage and am running
Python 2.7.12 and Anaconda 4.1.1, with numpy 1.9.3. When I run
mne.viz.plot_source_estimates on an stc object, I get the error:

ValueError: numpy.dtype has the wrong size, try recompiling

Am I using the right package versions?

Thank you and Best Regards,
Gladia

This can be caused by a dependency-related bug in Anaconda. Try doing
something like:

conda install numpy scipy matplotlib mayavi

If you then have problems using something like "sklearn", do:

conda install numpy scipy matplotlib scikit-learn mayavi

Basically the problem is that Mayavi needs an old version of NumPy, but
Anaconda doesn't resolve the dependencies properly, so you need to pass in
the names of all packages that compile against NumPy. See:
