General Questions and Answers / Adding Tags for moment tensor potential

« on: March 6, 2023, 01:59 »

I am trying to perform this example for bilayer MoS2 using moment tensor potential. https://docs.quantumatk.com/tutorials/combining_potentials/combining_potentials.html.

I have set tags for the the two layers (layer 1 and layer 2 as shown in the example above) and used MTP potential for the tagged layers. For interaction between the layers I use LJ potential. However, I get the following error while running the script.

Traceback (most recent call last):
  File "BL-MoS2.py", line 125, in <module>
    MtpPotential.actOnlyOnTaggedRegion('Layer1')
  File "build\lib\site-packages\tremolox\potentialsets\potentialsetbase.py", line 690, in actOnlyOnTaggedRegion
  File "build\lib\site-packages\tremolox\potentials\potentials.py", line 4346, in _limitToOneTag
RuntimeError: The MTP potential does not support the usage of tags

Is there anyway to resolve this problem?

Regards,
Akhil

Hi,

I am getting this following error while plotting scatter plots comparing the energy, force and stress computed from MTP and reference method.

Traceback (most recent call last):
  File "Plot.py", line 2, in <module>
    moment_tensor_potential_training._nlplotScatter(fit_index=0)
  File "zipdir\NL\Study\MomentTensorPotential\MomentTensorPotentialTraining.py", line 1661, in _nlplotScatter

  File "zipdir\NL\GUI\Graphics\Plotter\PlotView\PlotController.py", line 287, in _constructDelegateInFrameForItem
TypeError: 'NoneType' object is not callable

Also, Could anyone let me know what are the attributes for the Moment Tensor Potential Training object.
