Fbprophet快速入门示例 - KeyError：＆＃39; ds＆＃39;

Question

按照快速入门示例＆amp;在尝试使模型适合时遇到问题：

m.fit(df);

终端显示：

Traceback (most recent call last):
File "/home/cartier/miniconda2/envs/prophet/lib/python3.6/site-packages/pandas/indexes/base.py", line 2134, in get_loc
return self._engine.get_loc(key)

File "pandas/src/hashtable_class_helper.pxi", line 740, in pandas.hashtable.PyObjectHashTable.get_item (pandas/hashtable.c:13696)
KeyError: 'ds'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "prophexample.py", line 10, in <module>

当我打印头部，尾部或整个df时，它很好：

          ds          y
0  2007-12-10  9.590761
1  2007-12-11  8.519590
2  2007-12-12  8.183677
3  2007-12-13  8.072467
4  2007-12-14  7.893572

这是因为我没有使用笔记本电脑，还是我错过了其他东西？感谢

发现csv文件没有所有日期。日期从2008年7月13日至7月31日期间跳过。一旦我用一些随机y值输入缺失的日期就可以了。也许有一个设置/命令来忽略错过的日期...
