Im trying to do dpgen example for al in init process.

I am able to do till first principle simulations. all the FPMD are successful, but dpgen is unable to collect the data.
following is the error.

Traceback (most recent call last):

If anyone faced the above problem, please help.
Thank you.

Do you have solved this problem? I have meet the same problem.

I have met this probelm too. Do you know what is the reason for that?
I have kept 'md_nsteps' in param.json and 'NSW' in INCAR in agreement as the tourial tells me. However, there is still this problem.
I dont know what "find no valid OUTCAR" means.
