(resolved) the tqdm progress bar in the Jupiter notebook does not update and display in one line, but scrolls down to output

reason

Last time I used tqdm When , Its execution is not over yet , You interrupt .

terms of settlement

Of course, the roughest is for this notebook Conduct shutdown After ather , Destroy all objects （ Note the difference between restarting the server ）.

A more standard solution ： Use... In the way you create objects tqdm, And when the iteration breaks close() Method to manually destroy the unfinished progress bar , Such as ：

from tqdm import tqdm
# establish tqdm object 
t = tqdm(range(0,1000000))
# iteration 
for i in t:
	print(i)

Then play half way , You don't want to end , Press the interrupt button , In this case, you can use the following code :

t.close()

It shows , The execution position when you interrupt .
