[yt-users] Deprecation Woes

[Sam Skillman]

Hi Munier,

I think this should work:
In [1]: pf.domain_width.in_cgs()
Out[1]: YTArray([  2.80516144e+26,   2.80516144e+26,   2.80516144e+26]) cm

If you want just the number for some reason, you can do
pf.domain_width.in_cgs().d:
In [2]: pf.domain_width.in_cgs().d
Out[2]: array([  2.80516144e+26,   2.80516144e+26,   2.80516144e+26])

I would suggest looking at the documentation on the new units system:
http://yt-project.org/doc/analyzing/units/index.html#units

Sorry to hear that the upgrade to 3.0 brought unexpected consequences. We
tried to be as clear as possible about what changed, but I understand it
can be difficult to follow everything. You might find this page useful
going forward:
