503: SyntaxWarning: invalid escape sequence '\.'

[Georicl]

When I use braker an error has been encountered.
open errors/GeneMark-ET.stderr\

/ME4012_Vol0002/Ahome_Dir/waiyong/genome_build/Genemark/gmetp_linux_64/bin/gmes/ProtHint/bin/prothint.py:503: SyntaxWarning: invalid escape sequence '\.'
  systemCall('sed \"s/\.//\" ' + args.proteins + ' | sed \"s/|/_/g\" > ' +

so I open prothint.py
line 503 systemCall('sed \"s/\.//\" ' + args.proteins + ' | sed \"s/|/_/g\" > ' +
But when I rewrote it as systemCall('sed \"s/\\.//\" ' + args.proteins + ' | sed \"s/|/_/g\" > ' +
or systemCall(r'sed \"s/\.//\" ' + args.proteins + ' | sed \"s/|/_/g\" > ' +
It fails to run them all and shows no display at error and shows termination at the same place in GeneMark-ET.stdout\

# check before the run
# hard_mask is in the 'auto' mode. hard_mask was set to: 100
# creat directories
# commit input data
# prepare input data report

error, input sequence size is too small data/training.fna: 50000

The species I'm studying is oryzias curvinotus.Can you answer my current difficulties, thank you very much!
env：
Python 3.12.7
braker2 3.0.8
geneMark-ETP

@Georicl I encountered this issue before. In my experience, Python 3.12 caused the problem, so you should try downgrading to Python 3.11 or lower. I set my Python version to 3.11.9, and the error disappeared.

thank u gays!I'm going to try this way, I searched before for a possible error reporting bug in python 3.12.*, but this was supposedly waring in the previous version, just changed to error in this same one, I thought it was all stopping the process itself because of the error. @xo2003

Now I'm having a classic problem with my GeneMark reporting an error
error, input sequence size is too small data/training.fna: 50000
so I watch ./GeneMark-ET/data/dna.fna

How do I fix this error?
My input command is：

nohup perl braker/BRAKER-3.0.8/scripts/braker.pl --species=zj --genome=/ptah/to/genome.nextpolish.FINAL_rm29.fasta --bam=/path/to/1.bam --threads=20  &
