clojure - leiningen无法通过maven找到deeplearning4j工件

Question

我正试图在我的clojure/leiningen学习过程中迈出下一步。

我想在我的clojure项目中导入deeplearning4j。通过一些研究，似乎可以通过maven使用leiningen来实现这一点。根据tutorial的说法，maven库来自here。

我期望工作的过程是查找库(在本例中为deeplearning4j)，并将其添加到project.clj中：

(defproject to-remove "0.1.0-SNAPSHOT"
  :description "FIXME: write description"
  :url "http://example.com/FIXME"
  :license {:name "EPL-2.0 OR GPL-2.0-or-later WITH Classpath-exception-2.0"
            :url "https://www.eclipse.org/legal/epl-2.0/"}
  :dependencies [[org.clojure/clojure "1.10.1"]
                 [org.deeplearning4j/deeplearning4j "1.0.0-beta7"]]
  :main ^:skip-aot to-remove.core
  :target-path "target/%s"
  :profiles {:uberjar {:aot :all
                       :jvm-opts ["-Dclojure.compiler.direct-linking=true"]}})

但是我得到了一个错误：

Could not find artifact org.deeplearning4j:deeplearning4j:jar:1.0.0-beta7 in central (https://repo1.maven.org/maven2/)
Could not find artifact org.deeplearning4j:deeplearning4j:jar:1.0.0-beta7 in clojars (https://repo.clojars.org/)
This could be due to a typo in :dependencies, file system permissions, or network issues.
If you are behind a proxy, try setting the 'http_proxy' environment variable.

我试图添加:repositories密钥，但也没有成功：

(defproject to-remove "0.1.0-SNAPSHOT"
  :description "FIXME: write description"
  :url "http://example.com/FIXME"
  :license {:name "EPL-2.0 OR GPL-2.0-or-later WITH Classpath-exception-2.0"
            :url "https://www.eclipse.org/legal/epl-2.0/"}
  :dependencies [[org.clojure/clojure "1.10.1"]
                 [org.deeplearning4j/deeplearning4j "1.0.0-beta7"]]
  :main ^:skip-aot to-remove.core
  :target-path "target/%s"
  :profiles {:uberjar {:aot :all
                       :jvm-opts ["-Dclojure.compiler.direct-linking=true"]}}
  :repositories [["maven-org" "https://search.maven.org/"]
                 ["maven-source" "https://mvnrepository.com/"]])

给了我这个错误：

有没有人能帮我弄明白我哪里搞错了？

谢谢！

在你的project.clj中，使用id org.deeplearning4j/deeplearning4j-core，而不是org.deeplearning4j/deeplearning4j。您可能需要查看此information on Deeplearning4J dependencies，因为您可能还需要其他一些You。
