java - 引起：java.net.UnknownHostException：deeplearning4j 的 blob.deeplearning4j.org 问题

问题描述

我想运行，dl4jexamples/modelimport/ImportDeepMoji.java但它会引发异常

引起：java.net.UnknownHostException：blob.deeplearning4j.org

我该如何解决这个问题？

这是完整的错误日志

解决方案

现在使用系统属性https://deeplearning4j.org/api/latest/org/deeplearning4j/config/DL4JSystemProperties.html#DL4J_RESOURCES_BASE_URL_PROPERTY。

对于后代，该值为：-Dorg.deeplearning4j.resources.baseurl=$YOUR_CUSTOM_URL

在 IDE 或命令行中运行项目时。

当前版本在这里：https ://github.com/eclipse/deeplearning4j/blob/da4bf0209b5e2dab36f811603a381ac71f99fe66/deeplearning4j/deeplearning4j-common/src/main/java/org/deeplearning4j/common/resources/DL4JResources.java

您应该能够将值设置为： https ://dl4jdata.blob.core.windows.net/

所以命令行上的系统属性将是：-Dorg.deeplearning4j.resources.baseurl= https://dl4jdata.blob.core.windows.net/

如果您对此有疑问并且这不起作用，请在https://github.com/eclipse/deeplearning4j提出问题
