Attn: Sam Skillman (Matthew thinks you might know a solution)<br>
<br>
I'm attempting to follow the Simple Volume Rendering recipe given in the cookbook (<a href="http://yt-project.org/doc/cookbook/simple_plots.html#Simple_Volume_Rendering" target="_blank">http://yt-project.org/doc/<u></u>cookbook/simple_plots.html#<u></u>Simple_Volume_Rendering</a>). I'm using Ramses simulation output and after consulting Matthew Turk it should be fine, using the bleeding edge version, which I am. My code that fails is:<br>
<br>
pf = load(header)<br>
dd = pf.h.all_data()<br>
mi,ma = dd.quantities['Extrema']('<u></u>Density')[0]<br>
tf = ColorTransferFunction((np.<u></u>log10(mi)+1,np.log10(ma)))<br>
tf.add_layers(5,w=0.02)<br>
center=pf.domain_center<br>
look = [0.0,0.0,-1.0]<br>
width = 1.0<br>
res = 512<br>
cam = pf.h.camera(center,look,width,<u></u>res,tf)<br>
cam.snapshot("%s_test_snap.<u></u>png" % pf, clip_ratio=8.0)<br>
#Something fails in the progressbar of all places!<br>
<br>
I get a series of "Failed to split grids."<br>
<br>
It fails at snapshot, and at the end of the traceback I find:<br>
<br>
/data2/albert/ramses/yt-x86_<u></u>64/src/yt-hg/yt/extern/<u></u>progressbar/widgets.pyc in update_js(self, pbar)<br>
344 $myPB.progressbar({{value: 0, max: {pbar.maxval:d}}});<br>
345 }}<br>
--> 346 """.format(divid=self.uuid, pbar=pbar)<br>
347<br>
348<br>
<br>
ValueError: Unknown format code 'd' for object of type 'float'<br>
<br>
Any idea how to solve this easily? Possibly a good idea to optionally remove the progressbar in the future?<span class="HOEnZb"><font color="#888888"><br>
