【问题描述】：
我正在尝试从这个 url -“https://archive.ics.uci.edu/ml/machine-learning-databases/parkinsons/parkinsons.data”读取数据到 pandas 数据框。
我用过这个技巧：
park_df = pd.read_html('https://archive.ics.uci.edu/ml/machine-learning-
databases/parkinsons/parkinsons.data', header=0, flavor='bs4')
但我收到如下所示的错误：
---------------------------------------------------------------------------
ValueError Traceback (most recent call last)
<ipython-input-18-804373f977ab> in <module>()

402 if traceback == Ellipsis:
403 _, _, traceback = sys.exc_info()
--> 404 raise exc.with_traceback(traceback)
405 else:
406 # this version of raise is a syntax error in Python 3
ValueError: No tables found
您能否建议我在这里做错了什么，还有什么更好的选择。请务必打开 url 以检查数据的外观，第 1 行的标题（包含列名）和下面的数据。
