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

解决方案：

提示：尝试降低版本

例如：

      <dependency>
          <groupId>org.nd4j</groupId>
          <artifactId>nd4j-native</artifactId>
          <version>1.0.0-beta7</version>
      </dependency>

直到运行成功，免去升级系统lib库的烦恼
