Error writing hdf5 file

DocMusher

Hi, Please could someone explain why I receive an error writing an xls file into a hdf5 file. Is there another way to create hdf5 files in RM or external.
Thanks
Sven

Hi Sven,

The Write HDF5 operator requires a full file path, i.e. "/Users/username/Desktop/breast cancer.hdf5"

You can use the Folder symbol on the right side of the hdf5 file parameter to select the target folder.

But since Version 9.7 the regular Store operator also writes in the hdf5 file format inside of your RapidMiner repositories.

Greetings,
Jonas

Hi,

you have to append ?raw=true to the url to receive the actual binary from github.

Hi Jonas, using your approach I got the following message (see attachment)
In my original approach I downloaded the excel file and imported it in RM, next I used the write HDF5 which generated in an error message (see second attachment).

Thanks for any feedback
Sven
