SNAP

Hello everyone,

<br><br>

I'm trying to run processes from the Sentinel 1 toolbox of SNAP in the Terrascope VM, but I keep getting this or similar errors: `RuntimeError: Executing processing graph org.jblas.NativeBlas.dgemm(CCIIID[DII[DIID[DII)V`. A corresponding forum thread [1] suggests there is a problem with the SNAP version or the package libgfortran3, so I updated SNAP to 8.0.5 and tried installing available libgfortran packages (`sudo yum install -y libgfortran.x86_64 libgfortran-static.x86_64 libgfortran4.x86_64 libgfortran5.x86_64`), but it didn't help.

<br><br>

This is the case for trying to run a coherence process via the SNAP GUI, and also for running SNAP via the gpt tool of the Python pyroSAR package.

<br><br>

I'm wondering if anyone has experience with the S1tbx on the VM, or if this error ever occurred before? If not, it would be greatly appreciated if someone would take the time to try and reproduce my error. I put my workflow here [2]. When I load this graph into the graph tool of SNAP, it doesn't run and throws an error for the coherence process (see error message above). Does it do that on other machines as well?

<br><br>

Thank you in advance and best regards,

<br><br>

Jonathan

P.S.: I tried to structure this via html tags, ignore if it didn't work..
