Can't parse "center" error immediately upon starting training

[dave-mitchell]

Expected behavior

Describe, in some detail, what you are trying to do and what the output is that you expect from the program.
I expect the model to begin training and building previews and models using my data_src/ and data_dst/ image data in my workspace.

Actual behavior

Describe, in some detail, what the program does instead. Be sure to include any error message or screenshots.
After running extract frames, detect faces, sort, enhance, and then Xseg, I'm getting the following error when I start the training.
I'm using a Colab notebook, fwiw. I edited my warp.py file as instructed by /gaurang1123 in issue 5403 but that didn't fix the issue.

Steps to reproduce

Describe, in some detail, the steps you tried that resulted in the behavior described above.
The code to reproduce the issue is in the colab notebook for the project. Specifically the cell that's triggering the error is:

`#@title Training
Model = "SAEHD" #@param ["SAEHD", "AMP", "Quick96", "XSeg"]
Backup_every_hour = True #@param {type:"boolean"}
Silent_Start = True #@param {type:"boolean"}

%cd "/content"

#Mount Google Drive as folder
from google.colab import drive
drive.mount('/content/drive')

import psutil, os, time

p = psutil.Process(os.getpid())
uptime = time.time() - p.create_time()

if (Backup_every_hour):
if not os.path.exists('workspace.zip'):
print("Creating workspace archive ...")
!zip -0 -r -q workspace.zip workspace
print("Archive created!")
else:
print("Archive exist!")

if (Backup_every_hour):
print("Time to end session: "+str(round((43200-uptime)/3600))+" hours")

print("Time to backup: "+str(round((39600-uptime)/3600))+" hours")
backup_time = str(round(39600-uptime))
backup_cmd = " --execute-program "+backup_time+" "import os; os.system('zip -0 -r -q workspace.zip workspace'); os.system('cp /content/workspace.zip /content/drive/My\ Drive/'); print('Backed up!') ""
else:
print("Session expires in less than an hour.")
backup_cmd = ""

cmd = "DeepFaceLab/main.py train --training-data-src-dir workspace/data_src/aligned --training-data-dst-dir workspace/data_dst/aligned --pretraining-data-dir pretrain --model-dir workspace/model --model "+Model

if Model == "Quick96":
cmd+= " --pretrained-model-dir pretrain_Q96"

if Silent_Start:
cmd+= " --silent-start"

if (backup_cmd != ""):
train_cmd = (cmd+backup_cmd)
else:
train_cmd = (cmd)

!python $train_cmd`
