Hello,

I am using tqdm version 4.11.2 and pandas version 0.19.2.
When I try the minimal example

import pandas as pd
from tqdm import tqdm

tqdm.pandas()
df = pd.DataFrame({1:[1], 2:[2], 3:[3]})
foo = df.progress_apply(lambda x: x+1)

the output is

4it [00:00, 2616.13it/s]

instead of a progressbar counting up to 4.

Am I missing something? I took a short peek at the code, but total seems to be set correctly, so I am not sure what exactly is going on.

#299 seems to be a similar issue, but focuses on a different problem, I think.
