@rkazants can you please review and tell me what can I improve and why am I failing this case?

[chiruu12]

@fchollet hello sir can I get a little help on this one?

[nikolasavic3]

The formating test is failing. You might have trailing whitespace somewhere. did you run bash shell\format.sh locally in the root dir of your keras fork?

[chiruu12]

No sir i haven't

[nikolasavic3]

Can you do it? It will automatically rearrange your code so it passes the formatting test. Do you need any help with anything?

[chiruu12]

No sir, thanks. Could you please review my code once? I've implemented the logic, but I feel like it might not be fully utilizing OpenVINO's capabilities. Your feedback would be greatly appreciated.

@nikolasavic3 Sir, why am I getting this error?
