On Windows10, IntelliJ, Java 1.8, working through tensorflow-keras-import-examples and get above error. I’ve double checked the pom uses 1.0.0-beta7
@craig88 the dependencies look right in the examples. Could you paste a full stack trace? I suspect there’s another cause here.
How are you running it? Intellij?
Running IntelliJ on Windows, whenever I build/rebuild get this:
C:\DL4J\tensorflow-keras-import-examples\src\main\java\org\deeplearning4j\modelimportexamples\tf\advanced\tfgraphrunnerinjava\TFGraphRunnerExample.java:49:13
java: cannot find symbol
symbol: class GraphRunner
location: class org.deeplearning4j.modelimportexamples.tf.advanced.tfgraphrunnerinjava.TFGraphRunnerExample
@craig88 I’m still not seeing that. The whole example set compiles just fine. That class specifically comes from the nd4j-tensorflow module. Maybe just try running from normal maven command line? It seems like your IDE configuration is broken.
I installed the exact JDK version listed in the Quickstart:
mvn -v

@craig88 appreciated. Could you try the updated examples? I Just pushed an update to the examples that migrates it to the latest version. Thanks!
