dpdata cannot read OUTCAR file

[Gemstrom]

Hi, I am currently using deepmd-kit 2.2.1 and dpdata 0.2.16 installed via pypi to generate training data from VASP 5.4.4. OUTCAR. After running command:
data = dpdata.LabeledSystem('OUTCAR', fmt = 'vasp/outcar')
It gave an error message like:
Traceback (most recent call last):
File "", line 1, in
File "/envs/deepmdcpu/lib/python3.10/site-packages/dpdata/system.py", line 175, in init

I found a discussion that's similar here #275 (comment)
but a bit different. I'm not sure if the problems are similar.
Thanks in advance.

Could you provide the file?
