python - Pandas How to filter a Series

I have a Series like this after doing groupby('name') and used mean() function on other column

name
383      3.000000
663      1.000000
726      1.000000
737      9.000000
833      8.166667

Could anyone please show me how to filter out the rows with 1.000000 mean values? Thank you and I greatly appreciate your help.

In [5]:

import pandas as pd

test = {
383:    3.000000,
663:    1.000000,
726:    1.000000,
737:    9.000000,
833:    8.166667
}

s = pd.Series(test)
s = s[s != 1]
s
Out[0]:
383    3.000000
737    9.000000
833    8.166667
