Manual muti-line tqdm showing incorrect status

[garrettreid]

I'm having issues with using tqdm in manual mode with multiple progress bars. One bar (the inner loop/position=1) behaves correctly. The other (outer loop/position=0) behaves incorrectly. While my code should be stepping by 10% each time, I instead see 0%, 10%, 30%, 60%, 100%.

Here's the code, reduced as much as I can. It's just two loops. This implementation could work with iterable-based tqdm, but my end goal can't.

#!/usr/bin/env python
from time import sleep
from tqdm import tqdm

# Upper bar, outer loop
bar1 = tqdm(total=10, position=0, miniters=1)

for i in range(10):
    bar1.update(i)

    # Lower bar, inner loop
    bar2 = tqdm(total=10, position=1, miniters=1)
    for j in range(10):
        bar2.update(j)
        sleep(0.1)
    bar2.close()
bar1.close()

My system information:

import tqdm, sys
print(tqdm.__version__, sys.version, sys.platform)

Whoops. As things things were probably destined to go with a first github issue: I'm using the code wrong :)

tqdm.update() takes a value by which to increase the progress bar, not a total value to update to. After changing my code from bar1.update(i) to bar1.update(1) (and the equivalent for bar2), everything is working as expected.
