Error with dp train for liquid water cp2k trajectory

[deepakojha1]

Dear Developers/Users,
I used a small 100 frames trajectory of 216 liquid water cp2k trajectory with cp2k2data to obtain deepmd/npy format data. However when proceed with the training (dp train input.json) my calculations crash immediately. I used a input.json from the examples and modified it marginally to provide data path in my home folder. I am sharing the error message below:
