Hi Sam, Can you give a little bit more detail about how exactly you ran the setup script? The easiest way to do this is to clone the yt mercurial repository, pull Ben's changes into your local copy, then do "python setup.py develop" in the root of the repository. More detail here under "installing using pip or from source": http://yt-project.org/doc/installing.html On Sun, Nov 16, 2014 at 7:23 AM Sam Geen wrote:

Any ideas?

Hey Sam, I'm unable to reproduce this over here using "setup.py install" from 7d39049. It's a little suspicious that you needed to use sudo to install things, but that might also be a red herring depending on how your python environment is set up. FWIW, here's the sequence of commands I would use: hg clone https://bitbucket.org/yt_analysis/yt cd yt hg pull -r 7d39049 https://bitbucket.org/cosmosquark/yt hg up 7d39049 python setup.py develop Depending on how you've set up your python installation, that last command might need a "sudo" so it can put the egg-info file for the installation into your path. It might also be a good idea to clean out any old yt installations your have by repeatedly doing "pip uninstall yt". Python packaging, fun! -Nathan On Sun, Nov 16, 2014 at 11:16 AM Sam Geen wrote:

Hi Nathan,

I ran hg clone -r 7d39049 https://bitbucket.org/cosmosquark/yt then inside the yt folder sudo python setup.py install

I'll try your suggestion of cloning the main repo first instead.

Cheers,

Hi Sam. Just to add.. I have quickly rebuilt YT on my laptop... following Nathans instructions myself, my newly remade YT build imports fine. Sounds like it might be a build issue (uninstalling YT and rebuilding it from scratch) should do the trick (and yes, you may need sudo access for the python setup.py develop since python wants to (by default) build these packages within /usr/lib/python2.7/dist-packages ).

Thanks, will try that out! And yeah, I'm using the default python install directory on my laptop, hence the sudo (I should start using virtualenv, etc, I guess) Sam

Thomas Robitaille entered that movie for the 2014 scipy John Hunter plotting contest, and won! http://stsdas.stsci.edu/download/mdroe/plotting/entry6/index.html One nice piece of the plotting contest is that the source code had to be available, so you can see he blends the two volume renderings together: http://stsdas.stsci.edu/download/mdroe/plotting/_downloads/scipy_2014_entry....

I believe this email thread has more information on dealing with multivariate volume rendering:

http://lists.spacepope.org/htdig.cgi/yt-users-spacepope.org/2013-August/0140...

These emails are in reference to yt 2.x, but 3.0 shouldn't be substantially different. The gist of the solution is that you can do two volume renders for two different fields, then combine them in the end to a single image. Stella Offner created a good example of this in a movie which is featured on our webpage (5th one down):

I hope this helps!

Hi--I've got a question I'm hoping someone can help me with. I'm trying to do a volume rendering including 2 different fields whose scales differ by ~8 orders of magnitude. I'd like to be able to specify isocontours for specific values for each of the fields. I've been able to achieve this with just one field, but how can I do it for multiple fields?

Thanks.

Daniel
