Hello Bouchra,
Thanks for your message and for sharing the context.
To properly investigate the error “One or more layers do not have a name”, we’ll need to look directly at your model file. Could you please send it to me at y.menjour@graiphic.io if the file is not too large?
If the file exceeds email size limits, feel free to upload it using a service like WeTransfer and share the download link with us.
Once we receive the model, we’ll analyze the issue and get back to you with a concrete solution.
Looking forward to helping you!
