How can I show my information on the progress bar？

[xmy0916]

The default process bar like this,
Epoch 1: 4%|▎ | 40/1095 [00:03<01:37, 10.84it/s, loss=4.501, v_num=10]

If i want to display acc metric on process bar like this,
Epoch 1: 4%|▎ | 40/1095 [00:03<01:37, 10.84it/s, loss=4.501, v_num=10, acc=0.99]

What should I do？ thx~
