problem for "pymatgen.io.vasp.Poscar"

[Amadeus-System]

Hi. I have found (probably) Parsing Error in the conversion process from "POSCAR" to "structure"
I wanted to convert my POSCAR file to structure object in pymatgen.
but there's something wrong in the library or my code.

Here is my situation

As you see, there is a vasp calculation directory containing POSCAR file which is standard format of the VASP.
and this code was available in january 5, 2020. in the Googlecolab environment.
But today, when I rerun the same code, the error that I did not see occurs.
I think there's something wrong in the sre_parse.py code.

I would really appreciate if you help me.

Pls provide the actual text POSCAR in the issue report. Giving an image is very difficult for me to try to reproduce the error.

Here is my code. As you can see, it is very simple code. but it doesn't work.

!pip install pymatgen==2020.11.11  # you need to install pymatgen in googlecolab using this command!
 
# my code
from pymatgen.io.vasp import Poscar
poscar = Poscar.from_file('POSCAR') # in this part, the error occurs.
crystal = poscar.structure
crystal

I can't reproduce this error. It actually works on my end. As for googlecolab, since I don't use that platform, I can't really test it out on there. As far as I can see, all the unittests indicate the code is functioning as it should and on my end, running your code works.

Really??. Oh. Thank you. maybe it is about the problem in googlecolab.
I appreciate for your kind answer
