[yt-users] YT-3.0 - quick question - teething problems....

[John Regan]

Hi Britton,

I agree that should work but it seems my problems are deeper for some
reason.

If I do
###################################
import yt
filename = "RD0000/RD0000"

ds = yt.load(filename)
###################################
I'll get an error with:

(yt-x86_64)[regan at taito-login3 RT]$ pyyt test.py
Traceback (most recent call last):
  File "test.py", line 5, in <module>
    ds = yt.load(filename)
NameError: name 'yt' is not defined

For some reason my build isn't picking up the correct modules.

John
