Hi Gunturi, Rohini Bharadwaja,
Thank you for posting query in Microsoft Q&A Platform.
I could see, slash(/) at the end of file name, kindly remove that and try again. Also, if possible try to use little shorter file names and see if that helps too.
Hope this helps. If not, kindly share you dataset screenshot as well to understand better.
