Hi,
I find that ReadExcel seems strange, that is, sometimes it could not really read the data from excel.
For example, here are only two operators, one SetRole after ReadExcel:
<operator activated="true" class="read_excel" compatibility="5.0.11" expanded="true" height="60" name="Read Excel" width="90" x="45" y="30">
<parameter key="excel_file" value="C:\data\rm_into\GSPC Time Series Training Data.xls"/>
<list key="annotations"/>
<list key="data_set_meta_data_information"/>
</operator>
<operator activated="true" class="set_role" compatibility="5.0.11" expanded="true" height="76" name="Set Role" width="90" x="179" y="30">
<parameter key="name" value="close"/>
<parameter key="target_role" value="label"/>
</operator>
Then, it reports an error:
the attribute "close" is missing in the input example set. BUT, there does exist an attribute named "close" in the example set input by ReadExcel.
I also find that the out of ReadExcel shows that there is really none example set(i.e.,
number of examples = 0, and 0 attributes). If I delete SetRole, left ReadExcel only, the res will correctly shows the example set. What is wrong after I simply add another operator SetRole?
Thank you.
Sincerely yours,
gfyang
