#@title Select YOLOv5 ???? logger {run: ‘auto’}
logger = ‘Comet’ #@param [‘Comet’, ‘ClearML’, ‘TensorBoard’]

if logger == ‘Comet’:
%pip install -q comet_ml
import comet_ml; comet_ml.init()
elif logger == ‘ClearML’:
%pip install -q clearml
import clearml; clearml.browser_login()
elif logger == ‘TensorBoard’:
%load_ext tensorboard
%tensorboard –logdir runs/train

I refer this code from ultralyric YOLOV5 and after I run this code then show output as below

COMET WARNING: Failed to check backend version at URL: ‘https://www.comet.com/clientlib/isAlive/ver’
