That looks like a stacktrace out of a JVM crash file. Put that file on [gist.github.com](http://gist.github.com) and link that gist here. Whatever you are doing seems to result in a JVM crash while reading your HDF5 file. ---

Well, I’m not a compiler, so I’m not going to read all that code. I asked for the jvm crash file, it should be called something like `hs_err_pid.log` where `` is some number. ---

So you are using it in emulated x64 mode. I wonder if something about that may be the issue, as it is very unusual to see a segmentation fault at that particular place. @agibsonccc what do you think? ---

@treo I think this might be a data type overflow when hdf5 is reading the file. @Vamshi could you please DM me your model? I’d like to look at this. There’s only so much I can do but I can at least inspect what’s going on with the model file. ---

I recently saw a similar error importing a model on my Mac (failed on both an Intel and Silicon one) with error at: # V [libjvm.dylib+0x584935] jni\_SetLongField+0xc5 The error went away when I removed BatchNormalization from the first layer of model. I can try to regenerate and upload model if that would be helpful ---

@bjohnson yes that would be amazing thank you! ---

@treo @agibsonccc I am getting the same java runtime error as the one posted here by Vamshi. Were you able to find out what the problem is and how to resolve it? ---

@Vamshi could you find out what the problem was? I am experiencing a similar issue. ---

@nas-sh same question: do you have something I can see to reproduce this? ---

@agibsonccc you should be able to reproduce the error by importing our h5 file [here](https://github.com/sequoiarose/race/blob/smoke/race-earth/src/main/python/smoke-segmentation/smoke_segmentation_512.h5). Would you like to see the model in python also? On Java side, I use the following to import the h5 model which leads to the error in the native code: KerasModelImport.importKerasModelAndWeights(h5ModelPath, false);
