Hi, everybody, I have a problem when I execute this command: `java -jar xxxxx.jar` The problem is: ```auto Warning: Versions of org.bytedeco:javacpp:1.5.3 and org.bytedeco:cuda:10.1-7.6-1.5.2 do not match. 2020-10-14 15:27:03,165 - [WARN] o.n.l.f.Nd4jBackend - Skipped [JCublasBackend] backend (unavailable): java.lang.UnsatisfiedLinkError: /data/yuhao/.javacpp/cache/cuda-10.1-7.6-1.5.2-linux-x86_64.jar/org/bytedeco/cuda/linux-x86_64/libjnicublas.so: libcublas.so.10: cannot open shared object file: No such file or directory Exception in thread "main" java.lang.ExceptionInInitializerError at org.deeplearning4j.models.embeddings.loader.WordVectorSerializer.readWord2VecModel(WordVectorSerializer.java:2392) at org.deeplearning4j.models.embeddings.loader.WordVectorSerializer.readWord2VecModel(WordVectorSerializer.java:2372) at org.deeplearning4j.models.embeddings.loader.WordVectorSerializer.readWord2VecModel(WordVectorSerializer.java:2341) at com.sohu.modelupdate.CalculateCurrentModelPerformance.main(CalculateCurrentModelPerformance.java:43) Caused by: java.lang.RuntimeException: org.nd4j.linalg.factory.Nd4jBackend$NoAvailableBackendException: Please ensure that you have an nd4j backend on your classpath.

> [@dgqypl](#): > > `on: 10.1 ` @saudet ^ any ideas? It looks like a pretty normal configuration for cuda. ---

Well, the error message is pretty clear. If `libcublas.so.10` isn’t anywhere on your machine, reinstall CUDA. ---

Thanks @saudet so just a cuda install issue. I guess the redist artifacts are also valid here? ---

reference to this page: [https://deeplearning4j.konduit.ai/config/backends/config-cudnn](https://deeplearning4j.konduit.ai/config/backends/config-cudnn), it works!
