我尝试仅在python中读取sas文件头：
df = pd.read_sas(sas_file, chunksize=0)
对于日期我收到错误的文件不起作用：
/anaconda/lib/python3.5/site-packages/pandas/io/sas/sasreader.py in read_sas(filepath_or_buffer, format, index, encoding, chunksize, iterator)
59 return reader
60
---> 61 return reader.read()
/anaconda/lib/python3.5/site-packages/pandas/io/sas/sas7bdat.py in read(self, nrows)
587 p.read(nrows)
588
--> 589 rslt = self._chunk_to_dataframe()
590 if self.index is not None:
591 rslt = rslt.set_index(self.index)
/anaconda/lib/python3.5/site-packages/pandas/io/sas/sas7bdat.py in _chunk_to_dataframe(self)
632 if self.convert_dates and (self.column_formats[j] == "MMDDYY"):
633 epoch = pd.datetime(1960, 1, 1)
--> 634 rslt[name] = epoch + pd.to_timedelta(rslt[name], unit='d')
635 jb += 1
636 elif self.column_types[j] == b's':
/anaconda/lib/python3.5/site-packages/pandas/core/ops.py in wrapper(left, right, name, na_op)
649 lvalues = lvalues.values
650
--> 651 return left._constructor(wrap_results(na_op(lvalues, rvalues)),
652 index=left.index, name=left.name,
653 dtype=dtype)
/anaconda/lib/python3.5/site-packages/pandas/core/ops.py in <lambda>(x, y)
479
480 # pass thru on the na_op
--> 481 self.na_op = lambda x, y: getattr(x, self.name)(y)
482 return lvalues, rvalues
483
TypeError: ufunc add cannot use operands with types dtype('O') and dtype('<m8[ns]')
根据我的理解，它无法使用datetime转换列。 任何帮助将不胜感激。
