Subject Re: backward compatibility of models saved with 1.2.0
Date Tue, 29 May 2018 00:42:20 GMT
Hello Sergio,

you are right. We are following semantic versioning and thus, every model
produced within the same major version (e.g.1.x) has to be backwards

Could you please provide a small example so we can reproduce this? We
definitely do not want our users to retrain their model if they update
MXNet. That's a serious issue and we'd love to follow up.

Best regards,
