The frame.append method is deprecated and will be removed from pandas in a future version. Use panda

实例： 

train_pd = train_pd.append(data_pd_tmp.loc[:int((1-test_size)*data_pd_tmp.shape[0]), ['data', 'label']], ignore_index=True)
val_pd = val_pd.append(data_pd_tmp.loc[int((1-test_size)*data_pd_tmp.shape[0]):, ['data', 'label']], ignore_index=True)

改为： 

train_pd = pd.concat([train_pd,data_pd_tmp.loc[:int((1 - test_size) * data_pd_tmp.shape[0]), ['data', 'label']]],ignore_index=True)
val_pd = pd.concat([val_pd,data_pd_tmp.loc[int((1 - test_size) * data_pd_tmp.shape[0]):, ['data', 'label']]],ignore_index=True)
