Caused by: java.lang.ClassNotFoundException: org.tensorflow.ndarray.NdArray

The maven project that I have works fine if run it as Java Application. It does not raise error if I build it eclipse. This a FiJi plugin. As a result, if I copy paste jar file into "FiJi/plugins" or use "install plugins" I still do not have any problem. However, when I choose the plugin, it raises the following error.

In brief, I have models (tensorflow) trained using Python. Then, I load the models in tensorflow/java (0.3.1) . As I wrote above I do not have any problem (if I run the project as Java Application) loading the models and predicting images using tensorflow/java.

I am using windows, but I have the same problem if I run it on Linux as well.

Reproduisez l’échec en installant le JAR construit avec Maven dans Fiji et en sélectionnant le plugin ; la trace de pile entre dans org.scijava.plugin.PluginInfo.createInstance et signale que org.tensorflow.ndarray.NdArray n’est pas disponible. Inspectez les dépendances empaquetées du plugin et le classpath, puis vérifiez que le plugin démarre correctement dans Fiji sur les plateformes concernées.
