Title: problem about restarting from a check point
Post by: ATK-user-zuox on January 9, 2016, 06:48

Hello,recently i run a test script[Device.py] to set the

Code

DeviceLCAOCalculator( checkpoint_handler= CheckpointHandler('checkpoint-2.nc', 1*Minute),

and kille the job for restarting the jobs.i also get the [checkpoint-2.nc],but when i run the new py script[Device-restart.py], i get the  error message instantly

Code

Traceback (most recent call last):
  File "Device.py", line 495, in <module>
    device_configuration.setCalculator(DeviceLCAOCalculator(), initial_state= device_configuration)
  File "./zipdir/NL/CommonConcepts/Configurations/AtomicConfiguration.py", line 1222, in setCalculator
  File "./zipdir/NL/CommonConcepts/Calculator.py", line 58, in _supportConfiguration
  File "./zipdir/NL/CommonConcepts/Calculator.py", line 48, in _supportConfigurationType
  File "./zipdir/NL/Analysis/AnalysisUtilities.py", line 78, in checkConfiguration
NL.ComputerScienceUtilities.Exceptions.NLTypeError: The parameter, configuration, must be an instance of one of the following SurfaceConfiguration, DeviceConfiguration, NudgedElasticBand.

I have already read the Restarting stopped calculations toturial ,forum ,and the manual and i can't fix the problem in my code. Hope anyone could help! me!

The modified code i restart the job is

Code

device_configuration = nlread("checkpoint-2.nc",)[0]
device_configuration.setCalculator(DeviceLCAOCalculator(), initial_state= device_configuration)
nlprint(device_configuration)
device_configuration.update(force_restart=True)
nlsave('Device Gold.nc', device_configuration)

So this solves the problem?

Does this restart from where the simulation ended at 1 Minute ?

The jobs stopped instanly and  a another occurred :

Code

Traceback (most recent call last):
  File "Device.py", line 494, in <module>
    device_configuration = nlread("checkpoint-2.nc", DeviceConfiguration)[0]
IndexError: list index out of range

, i clear the

• and another error occurred:
  Code

  Traceback (most recent call last):[/li][/list]
    File "Device.py", line 495, in <module>
      device_configuration.setCalculator(DeviceLCAOCalculator(), initial_state= device_configuration)
  AttributeError: 'list' object has no attribute 'setCalculator'

  i will test the restarting function after running a long time .Did anyone can explain why i can't restart?

This means there are no DeviceConfigurations in the file "checkpoint-2.nc". Probably you never even got to the device part. It is probably better to start the job from scratch.
