NameError: name 'resample' is not defined

我正在尝试使用 python 中的重采样方法,但出现以下错误:

---------------------------------------------------------------------------
NameError Traceback (most recent call last)
<ipython-input-22-9ff5896e97a3> in <module>
----> 1 df_no_default_downsampled=resample(df_no_deafult,replace=False,n_samples=1000,random_state=42)
      2 df_default_downsampled=resample(df_deafult,replace=False,n_samples=1000,random_state=42)

NameError: name 'resample' is not defined

看来你需要DataFrame.sample:

df_no_default_sampled=df_no_deafult.sample(replace=False,n=1000,random_state=42)
