usingVASP-AIMD dpdata error

[WhiteCrosstheRiver]

I HAD ALREADY computed a DFT-AIMD nvt system，and got its OUTCAR for steps is NSW=500,and then I wanted using dpdata to prepare data,I always encounted this error.THANKYOUYOU!!!

@njzjz ,,,plzzz if you know some details about a Standardize data conversion process about VASP-AIMD-OUTCAR to Deepmd trained data，could you tell me？Or You really ever met this situation and get fixed well,too much thanks telling me so!!!

[njzjz]

Could you please provide OUTCAR for us to reproduce the error?

package.zip

THANKTOU TOO MUCH
THERE are INCAR POSCAR KPOINTS POTCAR as well as my OUTCAR
Basically speaking,my vasp-aimd computing procedure is alright okay ,however I don't know why I can't use dpdata to transfer.

[njzjz]

I've taken a look at OUTCAR and only find forces in the first and the last iteration.

OKKKAY,I HAVE SOLVED THIS QUESTION,THANKYOU TOO MUCH!!!!
-----------------------I change INCAR setting NWRITE=2 then it could trace every inoic step to give TOTAL-FORCE that dpdata tool needed,thankyou!!!
