dropping infinite values from datafram>me m>s in pandas?
... use the dropna:
df.replace([np.inf, -np.inf], np.nan).dropna(subset=["col1", "col2"], how="all")
For example:
In [11]: df = pd.DataFram>me m>([1, 2, np.inf, -np.inf])
In [12]: df.replace([np.inf, -np.inf], np.nan)
Out[12]:
0
0 1
1 2
2 NaN
3 NaN
The sam>me m> m>me m>thod would work for a Series.
