The accuracy of DP Gen based on DPA-2 pre trained model is 0 for each iteration

[JiangXiaoMingSan]

According to the notebook on Bohrium:DP-Gen based on a DPA-2 pretrained model(https://bohrium.dp.tech/notebooks/62585747598)
When I marked TiTaAlCrFeNiCo according to the notebook, the accuracy of each iteration was 0, and the specific status is as follows
#stage id_stg. iter. accu. cand. fail. lvl_f_lo lvl_f_hi
Stage 0 --------------------
0 0 0 0.0000 1.0000 0.0000 0.0035 0.5000
0 1 1 0.0000 1.0000 0.0000 0.0127 0.5000
0 2 2 0.0000 1.0000 0.0000 0.0122 0.5000
0 3 3 0.0000 1.0000 0.0000 0.0139 0.5000
I reproduced the example of water in the notebook and obtained an iteration accuracy of 0, and the specific status is as follows
#stage id_stg. iter. accu. cand. fail. lvl_f_lo lvl_f_hi
Stage 0 --------------------
0 0 0 0.0000 1.0000 0.0000 0.0056 0.5000
Each iteration has downloadable lable_data, which can be found in the folder called 'prep-run-fp/output/labeled_data'.
But the accuracy of 0 confuses me. Is this a normal phenomenon?

I tested this on a TiVZrNb system, which shows the same problem, but I think it may not be normal.

It seems that you are using dpgen2. what is the ratio of candidates? or you may provide the input file.

[JiangXiaoMingSan]

If you are referring to 'contue_on_success_ratio', the setting for this is 0.8. You can refer to this notebook(https://nb.bohrium.dp.tech/detail/62585747598?utm_source=mobile_bdsem) for the remaining input files. The accuracy of the examples we tested in this notebook is also 0, and our own program was modified through this

[wanghan-iapcm]

you have V_NSTEPS == 1000 and trj_freq==200, which means you record only 5 frames along the trajectory. by default at least 200 frames will be considered as candidate. thus you see all your configurations are candidates.

[JiangXiaoMingSan]

Thank you for your answer. I have modified the parameters in input.json and obtained the accuracy. By the way, I set V_NSTEPS==10000 and trjefreq==100 during the distillation process, with only 100 frames. But the status display has accuracy, should I change it to at least 200 to avoid potential issues?
