[BUG] dpdata support cp2k v2023.1
PolyuWeldingSpock opened this issue · 4 comments
Summary
dpdata cannot convert AIMD output into format deepmd needed. I run AIMD for 100 steps with cp2k 2023.1. Then I tried to use dpdata with commands:
import dpdata
dp = dpdata.LabeledSystem(cp2kmd_dir, cp2k_output_name=cp2kmd_output_name, fmt="cp2k/aimd_output")
print(dp)
Data Summary
Labeled System
-------------------
Frame Numbers : 0
Atom Numbers : 0
Including Virials : No
Element List :

Then I also tried to use cp2kdata. I have mentioned in robinzyb/cp2kdata#15.
I will upload my file for your need (https://1drv.ms/u/s!AtO91yh6_pLhg7BB7OnE5Cl8p7Cwbw?e=02Z6dW). I also want to know which file need to be revised to support newer version of cp2k such as dpdata/cp2k/output.py or some other files? I would like to revise the codes. Thank you.
I have the same issue. Turn out it is because the start line of coords are change from Atom Kind Element
to Atom Kind Element
(double space to single space), and a blank line is also removed from output.

@njzjz I think I confused this issue with another one. The fix works for cp2k/output
but not cp2k/aimd_output
. Anyway, I just fix the AIMD parse issue in cp2kdata
project: https://github.com/link89/cp2kdata/commits/fix-2023-support
Maybe you can consider to deprecate cp2k/aimd_output
and use cp2kdata/md
instead in dpdata
.
cp2k/output
and cp2k/aimd_output
are different impelementation. Fixing the one doesn't fix the other. In addition,cp2k/aimd_output
requires outputing forces into the cp2k stdout
, which is not the common practice of CP2K MD Users. I will in general recommend the style used in fmt=cp2kdata/md
where it parses -pos-
,-frc-
,ener
files generated by CP2K by default.
