I’ve written a jupyter notebook that processes Sentinel-2 data.
The notebook is here: https://github.com/ec-everest/e-learning-modules/blob/master/src/main/resources/e-learning/01%20Access%20Sentinel-1%20product%20information%20and%20metadata.ipynb
I’ve started a new VM and I run the code:
product = snappy.ProductIO.readProduct(s2prd)
width = product.getSceneRasterWidth()
height = product.getSceneRasterHeight()
name = product.getName()
description = product.getDescription()
band_names = product.getBandNames()
RuntimeError Traceback (most recent call last)
<ipython-input-23-94bf144a695c> in <module>()
----> 1 product = snappy.ProductIO.readProduct(s2prd)
3 width = product.getSceneRasterWidth()
4 height = product.getSceneRasterHeight()
5 name = product.getName()
RuntimeError: java.io.IOException: Invalid OpenJpeg executables
I’m running Linux.
Any help to understand what’s wrong here is really appreciated
Did you have a look at these threads?
Maybe they help you already.
Yes of course
The other threads are about Windows, we’re running Linux.
I was hoping somebody had a hint about the problem and I wonder if it’s not a conflict with OTB.
@marpet how does snappy/snap look for the OpenJpeg executables on Linux?
For info, under ~fbrito/.snap/auxdata/ I only have a folder called rgb_profiles
you should have more folders there, at least one called openjpeg containing the openjpeg executables. Have you tried to re-install snap? Perhaps something went wrong during the installation…
@marpet I believe the design of putting binaries in the user home is not the best approach.
How can we do a clean installation without writing dependencies in the user home?
Yes, this is probably not the best idea you’re right. But there is no way around at the moment.
@obarrilero Thanks! in fact we are repackaging SNAP and will apply a post-install of .snap
