@Nour-Rekik could you check the git hash you downloaded using git status? That nullpointer just being the resource seems very 1 off.  
It fails here:

> <https://github.com/deeplearning4j/deeplearning4j/blob/18e6dac62e5e0219599ac445b93014ac95672e87/nd4j/nd4j-backends/nd4j-api-parent/nd4j-api/src/main/java/org/nd4j/linalg/factory/Nd4j.java#L5148>

We obtain the reference to that here:

> <https://github.com/deeplearning4j/deeplearning4j/blob/18e6dac62e5e0219599ac445b93014ac95672e87/nd4j/nd4j-backends/nd4j-api-parent/nd4j-api/src/main/java/org/nd4j/linalg/factory/Nd4j.java#L5132>

What’s odd is some of the references work which would imply that this specific reference is missing.

I’ll try to see if I can reproduce this locally. I just want to make sure this is a recent version and I"m not chasing something that’s just an old dl4j version or something.

@Nour-Rekik Sorry could you try this?

```auto
git rev-parse HEAD

```

I don’t see the hash in there. I assume this clone is from the last few days? If so that should be enough for me to look at this.

Yes sure here the output:

Ok based on that I see what commit you’re on. I can work with this. Let me take a look locally. Thanks!
