CodePudding user response：

Use the subset argument to work on the whole dataframe:

df.dropna(subset=['string_tweet'], inplace=True)

CodePudding user response：

I guess, that the pictured nan are of type numpy.ndarray try to convert your column before droping the NaN.

df['string_tweet']=df['string_tweet'].astype(float)
