* Fix: Clear and print progress when tqdm is not available.
This relates two printing sequence:
(1) Print one decimal place after printing two decimal places
0.74/100 -> 0.8/100 (1 less character)
(2) Print 100/100 after printing decimal progress
99.74/100 -> 100/100 (2 less characters)
99.8/100 -> 100/100 (1 less character)
So clear the line first, and print progress, showing for a moment, and then repeat, finally a newline. :)
