A problem with enhance sampling

[Tgernew]

DPGEN version 0.11.0
Deepmd-kit version v2.1.1
I use the similar input with the examples and here is my model_devi input,

    {   "sys_idx": [0],"trj_freq": 10,"_idx": "00",

        "template":{ "lmp": "lmp/input.lammps", "plm": "lmp/plumed.dat" },

        "rev_mat":{ "lmp": {"V_NSTEPS": [20000], "V_TEMP": [300], "V_PRES": [1]},

                    "plm": {"V_TEMP":  [300], "V_STRIDE": [10]}

                  }
    },

but something went wrong during the model_devi process, the model_devi.log gives the error:

I'm sure both lammps and plumed were installed along with DPGEN, I'm wonder what can I do to fix this error? should I reinstalled DPGEN?

I think this problem is related to DeePMD-kit when loading Plumed plugins. Maybe you can find what's wrong by going into the folders where it runs.

Thanks alot, the problem has been solved. a previously installed plumed caused an error while it's running.
