Re: Java heap space error

[Andreas Forster]

Hi Jerry,

It seems that your JVM ran out of memory. The JVM does not take all your memory if you do not explicitly specify it. Did you pass the JVM options -Xmx2g  (see doc) to let it use 2 gigabytes of memory? If yes can you increase it even more e.g. -Xmx4g?

Hope this will fix the issue.

Best regards

Andreas

If it helps, this is what the visualizer looks like when I try to run it. When I ran one of the landmark files, it seemed to work, but the model tab is empty and trying to reload it or double click it does nothing.

Hi there,

I downloaded the Probabilistic Fitting tutorial, and added the model2017-1_face12_nomouth.h5 file into the data folder. I then ran the tutorial, but in all parts that require getting the shapeModel, I get the following error message:

java.lang.OutOfMemoryError: Java heap space

For example, I ran the following code line by line: 

import java.io.File

import scalismo.io.StatismoIO
import scalismo.statisticalmodel.StatisticalMeshModel

val modelLocation: String = "data/model2017-1_face12_nomouth.h5"
val shapeModel: StatisticalMeshModel = StatismoIO.readStatismoMeshModel(new File(modelLocation), "/shape").get

Every line worked successfully, included the modelLocation initialization, except for the last one. The shapeModel line produced the error I described above, and I believe at one point I got an error associated with no shape model being found. 

Do you have any explanation for this? Any help would be greatly appreciated!

Hi Jerry,

do you use 64bit JVM? And does your machine have enough (2gb) free memory when you start the tutorial?

Best regards

Hi Andreas,

I tried that using the command java -Xmx2g -jar scalismoLab-faces.jar but it gave the error "Could not reserve enough space for 2097152KB object heap" and I also went to my Java control panel and the runtime environment settings and changed the Runtime parameters to -Xmx4g, -Xmx2g, -Xmx512m, as well as with -Xms for all but I still got the error. Would you know why this is the case or a solution? Maybe I need to change permissions somewhere?

Note: It works if I do java -Xmx1g -jar scalismoLab-faces.jar and works for the most part, so it's just setting the allowable memory that's giving me the issue.

Thank you,

Jerry
