dataset = pd.read_csv("dataset.csv").fillna(" ")[:100] dataset['Id']=0 dataset['i']=0 dataset['j']=0 #... entries=dataset[dataset['Id']==0] print type(entries) # Prints <class 'pandas.core.frame.DataFrame'> entries=entries.sort_values(['i','j','ColumnA','ColumnB']) What might be the possible reason of the following error message at the last line?:
AttributeError: 'DataFrame' object has no attribute 'sort_values' 2 Answers
Hello sort_values is new in version 0.17.0, so check your version of pandas. In the previous versions you should use sort.
entries=entries.sort(['i','j','ColumnA','ColumnB']) Check pandas version, In new versions uses sort_values in place of sort.
