Hi,
I’m trying to implement ParallelInference.
But i got a crash from my JVM.
My model :
I start some thread and I replace implementation :
by :
ParallelInference model = pil;
if (isChiffre) {
model = pic;
}
with :
pic = new ParallelInference.Builder(chiffreModel).build();
Some idea about this bug ? How can I tune my JVM correctly ?
Cheers.
Can you share the error report file (C:\project\hs_err_pid5256.log)? It should contain some more information

is there an other way to get result from model ?
return Nd4j.getBlasWrapper().iamax(resultFiltered) + "";
you can just use Nd4j.argmax. Not really sure why you are even using iamax in the first place.
The AVX warning is just a warning, either you set up your system to use AVX2 for a bit of a speed improvement, or if you just want to get rid of it set the environment variable as it advises you to do.
For the error log, it would have been nice if you used something like gist.github.com.
It looks like the crash happened during loading of an image, not during the actual inference. And it looks like you are running this from multiple threads too.
@saudet
Is the NativeImageLoader not threadsafe?
Ok next time i will put stack on your link 
I wanted to filter the result and take the best output. I did not manage to tune my model other than with a softmax activation, but in case the outputs were not equal to 1 or 0, iamax took all its importance. iamax is right there for cases where I don’t have only 0 and one 1 but 0.999 and 0.001 and 0 …
I’m pretty new in ML.
iamax return an int and argMax an INDArray so.
int code = ((int) 'A') + Nd4j.getBlasWrapper().iamax(resultFiltered);
don’t work with argMax.
-15:20:39.108 - INFO — Starting MultiLayerNetwork with WorkspaceModes set to [training: ENABLED; inference: ENABLED], cacheMode set to [NONE]
what is cacheMode parameter and how can i change it if it improves performance ?
I think it’s legacy and can be removed now.
You should probably still use resultFiltered.argMax().toIntVector()[0].
Thank you for the information
@arnaud22, this is the reason for your crash. You have to use the Image Loader in a thread safe way.
@treo yes it’s better with resultFiltered.argMax().toIntVector()[0] !
When we do that :
NativeImageLoader loader = new NativeImageLoader(28, 28, 1);
try (INDArray filtre = contructFiltre(elementsPossible, isChiffre);
INDArray imgAOCR = loader.asMatrix(img);
INDArray resultFiltered = model.output(imgAOCR).muli(filtre);) {
if (isChiffre) {
return resultFiltered.argMax().toIntVector()[0] + "";
} else {
return ((char) ((int) 'A') + resultFiltered.argMax().toIntVector()[0]) + "";
}
} catch (Exception e) {
// On retourne _ comme si on avait rien trouvé
LOG.warn("probleme lors de la recuperation d'un caracterate", e);
}
imgAOCR is not close, is it normal ?
Thx for all your responses !
@treo For ParallelInference problem, when I don’t use Parallel Inference object it’s work but when i use it, I have the problem, maybe NativeImageLoader is not my only problem ?
I guess that it just makes the problem noticeable earlier. First make sure that you use the loader safely.
Hi @treo,
I think the loader is now safety but now i get this error :
Some ideas ?
Thx
PS : I remove ParallelInference for this test
This is weird. In principle model access is thread safe, as the access gets serialized across threads.
Does every one of your threads use its own model? Or are all of them using the same model?
@raver119 any other ideas what might be wrong here?
I load only one model, thanx for your quick response !
It’s impossible to tell anything based on this log. I need to have code that reproduces this problem
