Snappy error config installation

andverh · December 28, 2017, 7:44am

Hi All!
I try install snappy how described here: https://senbox.atlassian.net/wiki/spaces/SNAP/pages/50855941/Configure+Python+to+use+the+SNAP-Python+snappy+interface
When i run: snappy-conf <python-exe> <snappy-dir>, i get error: …

Closing the console will result in termination of the running program.

My PC config :
Win 10
Anaconda2 + python2.7
SNAP 6.0-PREVIEW5

My snappyutil.log: snappyutil.log (1,4 КБ)
snappy.ini: snappy.ini (216 Байт)

What should I change to properly configure it?

sorry to ask you that but did you type < python-exe > and so on or are they just placeholders in your example?

andverh · December 29, 2017, 2:24am

Of course, these are just placeholders, I did so:

ABraun · December 29, 2017, 7:57am

This is how it worked for me: Snappy.ini not found: make new one?

It is a bit different so maybe it helps you.

Falcon-Baikal · January 21, 2018, 6:38am

How do you solve the problem in the end???

andverh · January 22, 2018, 5:54am

Unfortunately, it was not possible to solve this problem. I even tried SNAP version 6.0.

marpet · January 31, 2018, 5:36pm

This error means that some library could not be loaded.
It is in a different scenario also mentioned on Stackoverflow
Maybe the error is that you have somehow mixed 32Bit and 64Bit. Maybe your anaconda is 32Bit and SNAP 64Bit? Could this be a reason?

mengdahl · January 31, 2018, 6:24pm

I switched this forum to read-only (except for admins) since SNAP 6.0 official is out. Perhaps this thread should be moved into an active forum?

andverh · February 9, 2018, 6:48am

It seems I was able to solve the problem in windows 10.

I did the following:

1). Install Microsoft Visual Studio 11.0
I have a variable VS110COMNTOOLS

2). Install jdk-9.0.4 and jre-9.0.4

3). set JAVA_HOME=c:\Program Files\Java\jdk-9.0.4
set JDK_HOME=JAVA_HOME
set PATH=PATH;c:\Program Files\Java\jdk-9.0.4\bin

I checked that it works:
java --version

4). Download apache-maven-3.5.2-bin.zip.
Unpack and move in c:\Program Files\

  set PATH=%PATH%;c:\Program Files\apache-maven-3.5.2\bin

 I checked that it works:
 mvn -v

5). Download jpy-master in C:\Users\andre\Downloads\

cd C:\Users\andre\Downloads\jpy-master
python setup.py --maven build

I checked that it works:

6). cd c:\Program Files\snap\bin\

7). snappy-conf c:\ProgramData\Anaconda2\python.exe c:\Users\andre\.snap\snap-python\snappy

8). python
import snappy
from snappy import ProductIO

It Works!!!

Hi

Thanks for this explanation.
I wonder having Visual Studio is necessary for a windows installation of Snappy? Why?

marpet · February 12, 2019, 12:06pm

There is a native part behind. It is called jpy. It is written in C.

It provides the bridge between python and java.

Sinooshka · February 12, 2019, 12:41pm

Thank you very much Marco,
Sounds very promising!
I was almost crying when I though I had to install VS.
If you don’t mind I will report issues on the installation of t “jpy” on my Windows and Linux here.

Sinooshka · February 12, 2019, 2:49pm

First Question :

Installing snappy (therefore jpy) on Linux Fedora 29 (64x)
Is it necessary to install a specific version of JKD (Is it OK to install the last version 11.0.2 ?)

The same question goes for installing it on windows 10 (64x)

Sinooshka · February 13, 2019, 4:54pm

Hi
I am trying to follow the procedures that you brought here.
So far I did everything accordingly except the fist step (installing Visual studio)
Instead I installed Microsoft Visual C++ (only because it is lighter than installing the whole VS monster)
But now I am stuck at step 5. It seems to me that it does not recognize the path to the compiler. Bu I also manually added the installation address to the system path. I do not have any clue where to go from here…

I would appreciate any comment on this.
Maybe I should install the whole Visual Studio package after all ?

Hello,

I have a similar issue with jpy. I have tried (unsuccessfully) many times to install SNAPPY with python 2.7.15 and 3.7.2. I use the SNAP GUI with no problem, but have never had any luck importing jpy or snappy.

Info:
MacOS 10.14.3, Mojave

java 11.0.2
Java™ SE Runtime Environment 18.9 (build 11.0.2+9-LTS)
Java HotSpot™ 64-Bit Server VM 18.9 (build 11.0.2+9-LTS, mixed mode)

After cloning the jpy repository,
git clone https://github.com/bcdev/jpy.git

and running the following line,
python setup.py --maven build jpy

I get the following warnings:

…and when running
python setup.py --maven bdist_wheel

It is successful, but with warnings:

Are you able to help? I’m happy to provide any further information as needed!

Thank you!

Hi
I am still trying to fix this issue on my windows machine. Have not so far been successful. However the recent answer of the user WALT-H in this page helped me to install correct VS build tools. I followed all the steps as Andverh suggested and I managed to have everything setup however at the end of step 5 I still can not import jpy. I installed python 2.7 and things are still the same.

yevkad · April 22, 2021, 7:15am

Not sure if this is still relevant, but I had exact same error as OP on Azure Ubuntu VM with very low (1GB) RAM. The error was solved by increasing RAM.
