I am getting the below error while running a sample python program from java.

return (PyInstance) this.interpreter.eval(className + "(" + opts + ")");
}
public static void main(String gargs[]) {
InterpreterExample ie = new InterpreterExample();
ie.execfile("hello.py");
PyInstance hello = ie.createClass("Hello", "None");
hello.invoke("run");
}
}
Not sure why it is conflicting with sikuli classes while running the sample java program.
Note: Python program works perfectly fine when they are executed directly. Problem raises only when the same program is called in java.
Could someone give a direction as to what is the approach to fix this?

cf Learning how to use Jython - ResourceWarning error
Jython currently only works with Python 2, you can't use Python 3 with it (for now), hence the error.

Open date setting in Kivy/Android app with jnius

I'm trying to translate this Java code
startActivity(new Intent(android.provider.Settings.ACTION_DATE_SETTINGS));
to Kivy, so I can open the Android date settings dialog. So far, I tried with
from jnius import autoclass
from jnius import cast
from jnius import autoclass
from jnius import cast
PythonActivity = autoclass('org.renpy.android.PythonActivity')
intent = autoclass("android.provider.Settings")
currentActivity = cast('android.app.Activity', PythonActivity.mActivity)
currentActivity.startActivity(intent.ACTION_DATE_SETTINGS)
but I'm getting
Traceback (most recent call last):
File "main.py", line 282, in read_queue

File "jnius/jnius_export_class.pxi", line 900, in jnius.jnius.JavaMultipleMethod.__call__ (jnius/jnius.c:27749)
JavaException: No methods matching your arguments
I tried several alternatives with setAction and setData but none works so far

How to call a python file using Tensorflow library in C++ environment?

When I tried to call a python file using Tensorflow library in C++ environment, I got a problem like this. I have no idea how to solve it.
This is my C++ code.
#include <Python.h>
#include <iostream>
int main(int argc, wchar_t** argv)
{
const char* picpath ="/home/senius/Pictures/zys.jpg";
Py_Initialize();
//PySys_SetArgv(argc, argv);
//PyRun_SimpleString("import sys\nprint sys.argv");
if ( !Py_IsInitialized() ) {
return -1;
}
PyRun_SimpleString("import sys");
PyRun_SimpleString("sys.path.append('/home/senius/Python/Ctensor/')");
PyObject* pMod = NULL;
PyObject* pFunc = NULL;
PyObject* pParm = NULL;
PyObject* pRetVal = NULL;
int iRetVal = -999;
const char* modulName="classify"; //这个是被调用的py文件模块名字
pMod = PyImport_ImportModule(modulName);
if(!pMod)
{
std::cout<<"Import module failed!";
PyErr_Print();
return -1;
}
const char* funcName="evaluate"; //这是此py文件模块中被调用的函数名字
pFunc = PyObject_GetAttrString(pMod, funcName);
if(!pFunc)
{
std::cout<<"Import function failed!";
return -2;
}
pParm = PyTuple_New(1);
PyTuple_SetItem(pParm, 0, Py_BuildValue("s",picpath));//传入的参数，是图片的路径
pRetVal = PyEval_CallObject(pFunc, pParm);//这里开始执行py脚本
PyArg_Parse(pRetVal, "i", &iRetVal);//py脚本返回值给iRetVal
//PyErr_Print();
std::cout<<iRetVal;
return iRetVal;
}
This is my python code.
from PIL import Image
import numpy as np
import sys
import tensorflow as tf
def evaluate(pic):
if not hasattr(sys, 'argv'):
sys.argv = ['']
image = Image.open(pic)
image = image.resize([256, 256])
image_array = np.array(image)
max_index = np.argmax([1, 2, 32])
return max_index
Once I import Tensorflow in python code, there will be a error. If I don't import Tensorflow, error disappears.
Error information is as followed.

AttributeError: module 'sys' has no attribute 'argv'

You import the tensorflow module - and during that import it attempts to use sys.argv (as you can see from your stack trade) and then sometime later in some function, you have
if not hasattr(sys, 'argv'):
sys.argv = ['']`
which is the workaround to this error - but it can never be called because the import failed.
The fix is to move this to before you import the tensorflow module

How to use Pygtk in a C/C++ application?

I would like to integrate a simple Pygtk window in a C/C++ application (The reason being a previously designed GUI in pyGtk is to be integrated into a bigger GTK+ (in C) application)
I get Segmentation fault error
Here what i did :
=====> In python (tmp.py):
#!/usr/bin/python
#from gi.repository import Gtk, Gio
win=Gtk.Window()
win.connect("delete-event",Gtk.main_quit)
win.show_all()
Gtk.main()
======> In C/C++ (simple.cpp):
i want to just execute that little window
#include <Python.h>
int main(int argc, char *argv[])
{
Py_SetProgramName(argv[0]); /* optional but recommended */
Py_Initialize();
FILE *fp = fopen ("tmp.py", "r+");
PyObject *mainModule = PyImport_AddModule("__main__");
PyObject * subModules = PyList_New(0);
PyList_Append(subModules, PyString_FromString("Gtk"));
PyList_Append(subModules, PyString_FromString("Gio"));
PyObject *Gtkstuff = PyImport_ImportModuleEx("gi.repository",NULL,NULL,subModules);
PyObject *GtkMod =PyObject_GetAttr(Gtkstuff,PyString_FromString("Gtk"));
PyObject *GioMod =PyObject_GetAttr(Gtkstuff,PyString_FromString("Gio"));
PyModule_AddObject(mainModule, "Gtk", GtkMod);
PyModule_AddObject(mainModule, "Gio", GioMod);
PyRun_SimpleFile(fp,"tmp.py");
Py_Finalize();
return 0;
}
The way how i compile is :
g++ $(python-config --cflags) -o simple $(python-config --ldflags) ./simple.cpp
The output :
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/usr/lib64/python2.7/site-packages/gi/importer.py", line 68, in load_module

if not initialized:
NameError: global name 'initialized' is not defined

This works perfectly, the rest of the code doesn't make sense to me, since you can do all the initialization in the python script.
#include <Python.h>
int main(int argc, char *argv[])
{
Py_SetProgramName(argv[0]); /* optional but recommended */
Py_Initialize();
FILE *fp = fopen("tmp.py", "r");
if (fp == NULL)
return 2;
PyRun_SimpleFile(fp, "tmp.py");
Py_Finalize();
fclose(fp);
return 0;
}

Cannot compile simple PyCuda OSX application

I've followed the PyCuda instructions here: http://wiki.tiker.net/PyCuda/Installation/Mac
I'm trying to compile the following code:
import pycuda.autoinit
import pycuda.driver as drv
import numpy
from pycuda.compiler import SourceModule
mod = SourceModule("""
__global__ void multiply_them(float *dest, float *a, float *b)
{
const int i = threadIdx.x;
dest[i] = a[i] * b[i];
}
""")
multiply_them = mod.get_function("multiply_them")
a = numpy.random.randn(400).astype(numpy.float32)
b = numpy.random.randn(400).astype(numpy.float32)
dest = numpy.zeros_like(a)
multiply_them(
drv.Out(dest), drv.In(a), drv.In(b),
block=(400,1,1), grid=(1,1))
print dest-a*b
And I'm receiving the following error:

I've searched google and found the following threads, but they don't help solve the issue; http://lists.tiker.net/pipermail/pycuda/2011-June/003244.html ...
TIA!

So the problem is that I hadn't installed a minor update from the nvidia control panel. After that and updating my bash_profile it works. Heh.
