How to remove the Validation in CaffeOnSpark？

hello，everyone I'm a newer for CaffeOnSpark. Now,i want to remove the Validation in CaffeOnSpark. I have encountered some problems

1、When I remove the test_iter and test_interval in the solve.prototxt .i get this erroe ：

###################################################################### INFO CaffeProcessor: Start augmeentation for train in CaffeProcessor StartThreads #

A fatal error has been detected by the Java Runtime Environment:

#

SIGSEGV (0xb) at pc=0x00007f34569bbad6, pid=1325[thread 139861169395456 also had an error], tid=0x00007f3489fec700

JRE version: Java(TM) SE Runtime Environment (8.0_121-b13) (build 1.8.0_121-b13)

Java VM: Java HotSpot(TM) 64-Bit Server VM (25.121-b13 mixed mode linux-amd64 compressed oops)

Problematic frame:

C [libcaffedistri.so+0x45ad6] CaffeNet::getValidationOutputBlobNames()+0x26

#######################################################################

what should I do to remove the validation in CaffeOnSpark？

2、when i adjust the number of the test_iter and test_interval in the solve.txt, the net receive the different number of input (Mat data ) . i want to know how does these parameters affect the number of iterations?

Thanks!

1) test_iter and test_interval set both to zero. 2) not sure about this.

thank you for your answer. what should I do with the train.prototxt ？ remove the test layer ?

thank you

[junshi15]

don't touch train.prototxt. your validation path will not run if you set both test_iter and test_interval to zero.

thank you , above problem has been solved but, I found some other questions this Queue is used to send data to Caffe，I have modified the code to send R-FCN data,but the picture and label mismatch（picture came 2 later than the label） then ,i find this code: `val Free: ArrayBlockingQueue[T] = new ArrayBlockingQueue[T] (2)

val Full: ArrayBlockingQueue[T] = new ArrayBlockingQueue[T] (2)`

i find the delayed length will be increase if i expand size of ArrayBlockingQueue[T] () (if the size is 3,the picture will be delayed 3)

thank you

You lost sync between labels and images. The QueuePair structure bundles them. The String is the label and the FloatBlob is for the image. Did you not do that in your modified code?

thank you, we've solved the problem. Thank you very much
