JSmile + python + MAC setup problem

Post by 3d93 » Wed Oct 26, 2016 9:40 am

Dear Genie & Smile Community,

I am a newbie in programming with Smile and it would be great if you could help me a little bit to start.

For my academia research project I am trying to setup the following configuration: JSmile + Python on Mac .
By following the instructions I successfully installed prerequisites (jpype).

Currently, I am having difficulties to import JSmile library in a python program .

Here is my testing py code that constantly returns the “ImportError: No module named jsmile” error message:
… from jsmile import SMILEException
ImportError: No module named jsmile …
Here is a small test program that I am using:

Code: Select all

#this part seems to work

import jpype 
jvmPath = jpype.getDefaultJVMPath() 
jvmArg = "-Xint"
jpype.startJVM(jvmPath,jvmArg)

# it seems that the following part is not working... here is the physical location of the 
#library at computer... I tried also to put only  “jsmile_macosx_x64” as a relative path
# to be concatenated to the absolute path without success.

from jpype import *  
import os.path  
jarpath = os.path.join('/Users/my_user_name/jsmile_macosx_x64/')

# tried to use some function from the JSmile library to test the code

from jsmile import SMILEException
net = jpype.JClass("smile.Network")

shutdownJVM()
I am probably doing something wrong but cannot figure out what.
Any help would be great. Thank you.

With kind regards,
Tom

The code below worked for me on Windows last time we were asked about using jSMILE with JPype. Let me know if you encounter any problems.

Code: Select all

import jpype  
jvmCP = "-Djava.class.path=FULL PATH (NOT ONLY DIR) OF YOUR smile.jar"
jvmLP = "-Djava.library.path=DIRECTORY CONTAINING libjsmile.jnilib"
jpype.startJVM(jpype.getDefaultJVMPath(),jvmCP,jvmLP)
jpype.java.lang.System.out.println("JVM started")
smile = jpype.JPackage("smile")
net = smile.Network()
print net.getName()

Dear shooltz,

thank you for your help and prompt response.
I think you helped me a lot.

Now my program responds with the following code:

Code: Select all

JVM started
Unnamed
[Finished in 0.3s]
I assume that is the right response and now I can continue to build my BN :-).
Thank you ...
Tom

Yes, the default string returned by the Network.getName() is "Unnamed".
