DPGEN with cp2k2022.1[BUG]

[cxliangUT]

Summary

Errors using DPGEN (DPMD+lammps+cp2k) in iteration step 08

DPGEN Version and Platform

DPGEN-0.11.0

Job submission and computing cluster configuration

DPGEN framework in local computer (everything is local, DPMD, lammps as well as CP2K)

Expected Behavior

The DPGEN normally runs

Actual Behavior

the program stops at iteration 00 step 08. The error message shows as:

Steps to Reproduce

just try DPGEN (DPMD-kit2.1.5+lammps+cp2k2022.1)

Interesting Findings
the cases we are working on is nothing but the methane cases in example.
we find that the problem comes from the dpdata in dpgen, when the dpdata reads the output file from cp2k, it will miss the coordinate of the first hydrogen atom. Then, the frames, number of atoms ,etc are obtained from the coordinates file, which gives the wrong information. We find that dpdata is accurate to read in the forces.

@robinzyb How about submitting a PR to migrate to the format in your cp2kdata package?

@robinzyb How about submitting a PR to migrate to the format in your cp2kdata package?

any suggestion? Specifically, I used a different format name, "cp2kdata/xx," instead of the original "cp2k/aimd." A simple solution is to replace the format name.

A simple solution is to replace the format name.

This looks good to me.
