how to run on ppc64le platform?

[liaocs2008]

I tried to build this project on ppc64le platform but unfortunately got following error:

java.lang.ExceptionInInitializerError
at TensorFlowNetSpec$$anonfun$1.apply$mcV$sp(TensorFlowNetSpec.scala:15)
at TensorFlowNetSpec$$anonfun$1.apply(TensorFlowNetSpec.scala:14)

The line 15 of "TensorFlowNetSpec" is to create an object from class GraphDef, which looks like coming from tensorflow package.

Do you think this would be the problem of javacpp-presets, i.e., not supporting ppc64le? Any help will be appreciated. Thanks!

Currently, ppc64le is not supported. If you get TensorFlow to build with JavaCPP on ppc64le, you can follow these instructions to create JARs: https://github.com/amplab/SparkNet/blob/master/doc/creating-jars.md

All right.

In fact, I already got jar packages (opencv, tensorflow and caffe) from javacpp-presets. This is due to recent updates from JavaCPP. But there is another problem as following:

[info] Converting NDArray to Tensor and back
[info] - should preserve its value *** FAILED ***
[info] java.lang.Exception: The shape of t does not match the shape of array. t has shape Array() and array has shape Array(1000000)

To pass test, that line is commented in file TensorFlowNetSpec.scala. So finally a jar file can be generated. I run test on cifar dataset but following error pops out:

I0630 05:14:20.276917 161220 net.cpp:106] Creating Layer conv1

Do you have any idea what is wrong here? Anyway, do you have plan to support ppc64le in future?
