【问题描述】：
我正在尝试使用 Pandas 库中的 read_csv 将数据框导入 Python。数据文件 (annual_precip.csv) 的顶部如下所示：
Average annual precipitation and land area ,,
,mm/year,thousand km^2
country,precip,area
Afghanistan,327,652.2
Albania,1485,27.4
Algeria,89,2381.7
American Samoa,,0.2
这是我的代码：
from pandas import read_csv
read_csv('annual_precip.csv', index_col = [0], skiprows = 2)
这会产生以下错误：
Traceback (most recent call last):`
File "<ipython-input-894-742b462476f6>", line 1, in <module>
rain =read_csv('exploratory_computing_with_python/notebook5/annual_precip.csv', skiprows = 2, index_col = [0])`
File "/Users/jakoberickson/anaconda/lib/python2.7/site-packages/pandas/io/parsers.py", line 465, in parser_f
return _read(filepath_or_buffer, kwds)`
File "/Users/jakoberickson/anaconda/lib/python2.7/site-packages/pandas/io/parsers.py", line 241, in _read
parser = TextFileReader(filepath_or_buffer, **kwds)`

File "pandas/parser.pyx", line 512, in pandas.parser.TextReader.__cinit__ (pandas/parser.c:4804)`
ValueError: No columns to parse from file`
当我跳过 1 或 0 行但我的列名称不正确时，我没有收到任何错误。如果这有什么不同，我正在优胜美地的 Anaconda 包中运行 Spyder 2.3.4。
