ご相談事項

現在、参考書に習いpythonでpandasを利用しており、以下のCSV読み込み時にエラーが出ます。
修正すべき箇所がどこかご指摘いただけないでしょうか。

コード

import urllib.request as req
import pandas as pd

#ファイルDL
url = "https://github.com/pandas-dev/pandas/blob/master/pandas/tests/data/iris.csv"
savefile = "iris.csv"
req.urlretrieve(url, savefile)
print("DL copmlete")

savefile

#ファイルの内容表示
csv = pd.read_csv(savefile, encoding="utf-8")
csv
