I am always getting this while running RNN . Any help would be great at this point

I vaguely remember that there are issues when using Spring Boot due to the way it does class loading.
How exactly are you running this?

Thanks @treo for your response.
Exactly its through spring boot.
curl -XGET “calling URL”

I mean, is it running as a single uber jar? If yes, try opening the jar with something like 7zip, and take a look inside to see if everything is in the right place. In particular if you’ll find more jar files inside, there may be problems with loading.

Yes its a uber jar, as its one small application of text generation using LSTM. The list of jars are in the below response.
In case if you know that a particular jar/jars are the problematic ones from the below list, you may let me know @treo , and i will give it a shot , removing those and checking again

The problem isn’t the jars itself, but how spring boot packages and then loads things.
The only thing I can suggest is that you look into an alternative way to package the application.
See: [The Executable Jar Format](https://docs.spring.io/spring-boot/docs/current/reference/html/executable-jar.html#appendix.executable-jar.alternatives)

Will give it a try. Will run a normal java jar and then try. Thanks @treo for a way out !
