本文介绍在本地开发环境中正常运行的Nd4j在服务器部署时遇到的异常，主要表现为 UnsatisfiedLinkError，通过降低Nd4j版本并提供合适的依赖，解决因版本不匹配导致的缺失依赖问题。

Nd4j 运行异常解决方案

使用Nd4j版本

      <dependency>
          <groupId>org.nd4j</groupId>
          <artifactId>nd4j-native</artifactId>
          <version>1.0.0-M1.1</version>
      </dependency>

本地开发环境运行正常，但部署到服务器环境运行异常
