Numenta-htm.java-示例-Ubuntu-Eclipse-NetworkAPIDemo-NoClassDefFoundError：no / uib / cipr / matrix / sparse / FlexCompRowMatrix

Question

我在嘗試參考htm.java-examples運行NetworkAPIDemo示例時遇到問題，如果嘗試運行代碼， 則會收到錯誤消息：

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

如果我將依賴項添加到POM文件中：

com.googlecode.matrix-toolkits-java.mtj.1.0.2

我得到錯誤：

我同時遇到了openjdk1.8和oracle_jdk1.8的問題。

com.googlecode.matrix-toolkits-java.mtj.1.0.2可以在.m2文件夾中找到（我在Eclipse中使用Maven）。

我嘗試在兩台計算機上運行它，但它可以在其中一台計算機上運行，​​但是同一代碼在另一台計算機上不起作用。 我沒有理會Cortico的示例，因此外部庫應該不會造成任何問題。 在POM文件中，我僅指定依賴項

org.numenta.htm.java.0.6.13

如果添加外部庫（可以在libs文件夾中找到），則會收到錯誤消息：

Exception in thread "main" java.lang.NoSuchMethodError: org.numenta.nupic.Parameters.set(Lorg/numenta/nupic/Parameters$KEY;Ljava/lang/Object;)V
    at Intro2.NetworkDemoHarness.getParameters(NetworkDemoHarness.java:211)

    at Intro2.NetworkAPIDemo.<init>(NetworkAPIDemo.java:62)
    at Intro2.NetworkAPIDemo.main(NetworkAPIDemo.java:242)

我不是從源代碼構建項目，而是僅在POM.xml文件中指定了依賴項。 可以在.m2文件夾中找到org.numenta.htm.java.0.6.12。 我嘗試使用htm.java的0.6.13版本，但遇到了相同的問題。

POM.xml包括：

• 指定Java 1.8的Maven編譯器

• 指定htm.java依賴項

我正在使用Java的Ubuntu 16.04：

java version "1.8.0_131"
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)

運行：

mvn clean install

成功，有兩個警告和一個錯誤：

[WARNING] Using platform encoding (UTF-8 actually) to copy filtered resources, i.e. build is platform dependent!
[ERROR] error reading /home/szi/.m2/repository/algorithmfoundry/algorithmfoundry-shade-culled/1.3/algorithmfoundry-shade-culled-1.3.jar; invalid LOC header (bad signature)

運行：

mvn -e exec:java -Dexec.mainClass="/home/szi/Documents/Eclipse/Java/HTM/src/main/java/Intro2/NetworkAPIDemo.java"

有人可以給我關於什么是錯的建議嗎？ 我從github倉庫中復制粘貼了代碼，沒有進行任何修改。

感謝您的任何幫助！

Answer 1

問題解決了！

如果有人遇到相同的問題，則應將庫algorithmfoundry-shade-culled-1.3.jar添加到您的項目中。
