• How to reproduce the issue ? (This is for errors. Please share the command line and the detailed log here.)
When we run training with yolov3 training tutorial notebook as i posted the link below

After stating the training , i tried to run the tensorboard monitoring with below command
tensorboard --logdir yolov3_init_test:training_home/yolo_v3/experiment_dir_unpruned/ --host 0.0.0.0 --port 8080

The directly is the parent directory of where the weights folder is there

But when i run the command i can able to access the tensorboard webpage
But i saw error in the terminal so i didn’t get any details in the page

The error is

Can you support on this

Is there expected result from the tensorboard webpage?
Do you mean it is find in tensorboard webpage but see an error in the terminal?
