Hi Ariel, Ah, sorry it threw the error! If you are on Ubuntu, try: sudo apt-get install uuid-dev And let us know if that fixes it. You should be able to simply rerun the script after this. -Matt On Aug 4, 2012 9:05 PM, "Ariel Werle" <ariel.werle(a)gmail.com> wrote:

YT installation
by Sherwood Richers Aug. 4, 2012

Aug. 4, 2012

Hello, I tried installing YT on my (Ubuntu 12.04 x86_64) laptop and got the following error messages when the install script tried updating. I also tried starting python and executing "import hashlib" and got the same messages. Does anybody know the cause of this or what I can do to fix the errors? (I don't know if it's of any relevance, but there were also a bunch of warnings in the attached install log). Thanks a ton. -Sherwood Installing Forthon-0.8.5 (arguments: 'Forthon-0.8.5') Doing yt … [View More]

Re: [yt-users] Quiver normalization
by Massimo Gaspari Aug. 2, 2012

Aug. 2, 2012

Thank you JC, the plot looks better. So, on any png image produced by YT, if I set "inches", the arrow unit length is always exactly one inch? Or is there any kind of device rescaling (e.g., using different resolutions)?

Quiver normalization
by Massimo Gaspari Aug. 1, 2012

Aug. 1, 2012

Hi guys, how can I set a given normalization for the velocity field superposed to a slice? p.modify["velocity"](factor=13) I am a bit puzzled by the "scale" keyword. E.g., I want to set 1000 km/s as the normalization for all the slices of a simulation. Thanks, Max
