Ferroelectric workflow job gets fizzled after static calculation

[bisha...@gmail.com]

Dear all,

I am having some trouble with polarization calculation using atomate. The workflow starts and then gets fizzled after a single static calculation for polar and non-polar structures. Both the structures are already relaxed and have non-zero band gap. I have previously computed polarization manually for this structure.

2019-04-23 17:09:15,600 INFO atomate.vasp.firetasks.glue_tasks The gap is: 2.0357999999999996. Min gap: 0.01. Max gap: None

2019-04-23 17:15:23,349 INFO atomate.vasp.firetasks.glue_tasks The gap is: 1.9252000000000002. Min gap: 0.01. Max gap: None

I get the following error:

My input is as shown below:

polar = Structure.from_file('POLAR.vasp')  

nonpolar = Structure.from_file('NONPOLAR.vasp')  

wf  =   get_wf_ferroelectric(polar_structure=polar, nonpolar_structure=nonpolar, vasp_cmd="vasp_std", db_file=None,vasp_input_set_polar="MPStaticSet",        vasp_input_set_nonpolar="MPStaticSet",relax=False, vasp_relax_input_set_polar=None, vasp_relax_input_set_nonpolar=None, nimages=5, hse=False, add_analysis_task=False, wfid=None,tags=None)

lpad.add_wf(wf)

Hi Bishal,

To help diagnose this error, could you please let us know: are the VASP files from this workflow gzipped upon completion?

Thank you,

Hi Bishal,

I've never seen this error and it looks like an encoding problem of some sort which may be system dependent.

If your output files are gzipped, can you try rerunning after setting {'gzip_output': False} in RunVaspCustodian here?

Best,

Tess

Hi Tess,

Your suggestion worked. I am not getting that error anymore.

Thanks
