[Jepp-users] python_modules

[V. B. <var...@gm...>]

Dear Mike Johnson!

It's me again.
I'd like to use modules in my python code. But I think jep cannot handle 
properly.

For example:

>>>from  sklearn  import  linear_model
>>>clf  =  linear_model.LinearRegression()
>>>clf.fit  ([[0,  0],  [1,  1],  [2,  2]],  [0,  1,  2])
LinearRegression(copy_X=True, fit_intercept=True, normalize=False)
>>>clf.coef_
array([ 0.5,  0.5])

Jep seems like run forever after the first line (no error message or 
exception), but the code works if I run it from the python interpreter 
'manually'.

It doesn't work neither if I use it in this way:

import sklearn
clf  =  sklearn.linear_model.LinearRegression()
...same as above...

In this case I get the following error message:
"SEVERE: null
jep.JepException: jep.JepException: <type 'exceptions.AttributeError'>: 
'module' object has no attribute 'linear_model'
     at jep.Jep.eval(Jep.java:294)
     at Main.executeScript(Main.java:72)
     at Main.main(Main.java:36)
Caused by: jep.JepException: <type 'exceptions.AttributeError'>: 
'module' object has no attribute 'linear_model'
     at jep.Jep.eval(Native Method)
     at jep.Jep.eval(Jep.java:278)
     ... 2 more"

My only working version with modules is:

import numpy as np
beta = np.array([1, 0.1, 10])

So I need a solution in order to
- use code: 'module.submodule.subsubmodule'
- use import: 'import module.submodule' and use code: 
'submodule.subsubmodule'
If one of these solutions work, I would be happy.

Is it possible?

I'm using python 2.7.2 and jep 2.4. I know there's a newer version of 
jep but for me it was hard to configure 2.4. too, so I wouldn't install 
a newer if it's unnecessary.
(Because it was time consuming for me. I had to compile a totally new 
python interpreter with ucs4, copy the installed python packages from 
dist-packages to site-packages, set environment variables and so on.)

Yours sincerely,
