Pythonで始める機会学習の第4章の下記のサンプルコードを実行したのですが
%matplotlib inline from preamble import *
import os # The file has no headers naming the columns, so we pass header=None # and provide the column names explicitly in "names" adult_path = os.path.join(mglearn.datasets.DATA_PATH, "adult.data") data = pd.read_csv( adult_path, header=None, index_col=False, names=['age', 'workclass', 'fnlwgt', 'education', 'education-num', 'marital-status', 'occupation', 'relationship', 'race', 'gender', 'capital-gain', 'capital-loss', 'hours-per-week', 'native-country', 'income']) # For illustration purposes, we only select some of the columns data = data[['age', 'workclass', 'education', 'gender', 'hours-per-week', 'occupation', 'income']] # IPython.display allows nice output formatting within the Jupyter notebook display(data.head()) Initializing from file failed
以下のようなエラーがでてしまいます。このような場合はどうすればエラーを解決できるでしょうか??
