Jpy Python-Java bridge version


Perfect, this is what I was looking for!

Thanks Andreas,
Best regards,


I have installed snap-python, but I am getting this error “nest is not a win32 valid application” in examples as follows:


I correctly installed and configured snappy as:

cd /snappy
cd install

is C:\Users\toshiba.snap\snap-python

I verified the installation folder of the snappy in my python-package installer


However, when I try to run the test on an example :

from snappy import ProductIO
p = ProductIO.readProduct(‘snappy/testdata/MER_FRS_L1B_SUBSET.dim’)

I get the following error:

File “c:\Users\toshiba.snap\snap-python\snappy\examples\”, line 4, in
from snappy import Product
File “C:\Python27\lib\site-packages\”, line 63, in
File “C:\Python27\lib\site-packages\snappy\”, line 315, in preload_jvm_dll
return ctypes.CDLL(jvm_dll_file, mode=ctypes.RTLD_GLOBAL)
File “C:\Python27\lib\”, line 365, in init
self._handle = _dlopen(self._name, mode)
WindowsError: [Error 193] %1 nest pas une application Win32 valide


nest is not part of snappy nor SNAP
Is it maybe an additional python package you have installed or some other application?

Do you have the old Nest application installed? But actually this should not interfere with SNAP/snappy.

I don’t know where this error comes from


EDIT: The replies are not below the actual thread above, so to preface:

I am following this thread and perform python ./ -j -p after following the instructions here.

However, without the options -j -p it works just fine.

I am trying to follow these instructions to install jpy (for SNAP), but am getting the following error:

RuntimeError: can't find any Python shared library

The specs are:

  • Mac OS High Sierra / Unix (10.12.6)
  • python 3.6.3

A similar error occurs when I run $ ./snappy-conf <python-exe> per the confluence page.

Assume there are new comments/instructions, but having trouble finding them.
