Hi Sam, it was a bug. I filed https://github.com/yt-project/yt/issues/2578 to track it and there's a corresponding fix here: https://github.com/yt-project/yt/pull/2579. If you cannot apply that patch locally to the yt installation on that machine (e.g. it's a cluster administered by someone else), I'm afraid you'll have to install a development version of yt and pull that change.

Hello,

I've run into a problem when trying to initialize a simulation object with a start time and finish time. My code is:

import yt from yt.units import Myr

simulation = yt.simulation("DD0005/output_0005", 'Enzo') simulation.get_time_series(initial_time= 284.098 * Myr, final_time= 284.292 * Myr, redshift_data=False)

Trying to run this script results in the following error:

Traceback (most recent call last):   File "mini_test.py", line 5, in <module>     simulation.get_time_series(initial_time= 284.098 * Myr, final_time= 284.292 * Myr, redshift_data=False)   File "/opt/apps/pkgs/cpython/3.7.1/intel64/intel_2019.2/lib/python3.7/site-packages/yt/frontends/enzo/simulation_handling.py", line 292, in get_time_series     my_initial_time.convert_to_units("s") UnboundLocalError: local variable 'my_initial_time' referenced before assignment

Any help on this issue would be much appreciated.

Many thanks, Sam Patrick _______________________________________________ yt-users mailing list -- yt-users@python.org To unsubscribe send an email to yt-users-leave@python.org https://mail.python.org/mailman3/lists/yt-users.python.org/ Member address: xarthisius.kk@gmail.com
