Pandas Read_csv Error Oserror



次のコードを実行します。

import os import pandas as pd import requests PATH = 'F: / Machine Learning / Python-Machine-Learning-Blueprints (python Machine Learning Practice Guidelines) / Chapter 01 / iris /' r=requests.get('https://archive.ics.uci.edu/ml/machine-learning-databases/iris/iris.data') with open(PATH+'iris.data','w') as f: f.write(r.text) df=pd.read_csv(PATH+'iris.data', names=['sepal length', 'sepal width', 'petal length', 'petal width', 'class'])

与えられた結果：

パス、ファイル名はそのままです。エラー1048で、Cエンジンのデフォルトを使用してread_csv pandas（）メソッドを呼び出すことがわかった場合、ファイルパスに中国名が含まれていると、Cエンジンを使用すると文句が表示されます。エンジンはPythonに変更され、この問題を解決できます。

解決策：エンジンがPythonであることを指定します



df=pd.read_csv(path, names=['sepal length', 'sepal width', 'petal length', 'petal width', 'class'], engine = 'python') # engine as specified Python
