问题描述
这是文件：
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

<dependency>
<groupId>org.nd4j</groupId>
<artifactId>nd4j-native-platform</artifactId>
<version>1.0.0-beta7</version>
</dependency>
</dependencies>
</project>
我正在尝试添加deeplearning4j
我得到的错误是（我在IntelliJ中工作）
<project" has a red underline saying "For artifact {org.example:neural:null:jar}: The version cannot be empty.
<artifactId>nd4j-native-platform</artifactId> <version>1.0.0-beta7</version>" is red,saying "Dependency 'org.nd4j:nd4j-native-platform:1.0.0-beta7' not found
感谢您的帮助。
解决方法
我建议使用intellij的Maven原型并自定义该模板或模板项目： https://github.com/eclipse/deeplearning4j-examples/tree/master/mvn-project-template 我知道在stackoverflow上不允许只有链接的答案，所以我总结一下：

您可以使用dl4j快速入门来告诉您更多信息。实际上，您应该尝试从现有项目开始，并尽可能导入为Maven项目。如果不是，请在intellij中创建一个原型原型的新Maven项目并对其进行自定义。通常我们使用Java快速入门。
,您没有pom.xml的版本
更改此：
<groupId>org.example</groupId>
<artifactId>neural</artifactId>
对此：
<groupId>org.example</groupId>
<artifactId>neural</artifactId>
<version>1.0.0</version>
