Error in building iotivity for android on windows

Can someone help me with this error, I can't seem to identify the problem. I am also new in using Scons. I need to get through this to obtain the .aar and .apk files. I am using Iotivity for a project that allows users to share transfer images between devices of any platform without internet.

It's broken. I guess I'm the one who broke it when I tried to clean up that part of the build some years ago. The iotivity project CI system does not build android binaries on a windows host, it uses a linux builder for that, and I guess no developer did either so nothing detected the problem, which as the error message says, is that host_arch is undefined. This is not fundamental to iotivity, it's just dependency work to set up the Android NDK; once you have one set up this stuff is skipped for subsequent builds. The previous version switched on target_arch which wasn't right - the bundle to get depends on the host, not on what you're building for. I think the Android project stopped supporting 32-bit bundles a while back anyway so the simplest way to move forward is to remove the test (unless for some reason you have 32-bit Windows). That is, change this chunk starting with line 23:
else:
if host_arch in ['x86_64']:
ndk_url = ndk_url_base + '-windows-x86_64.exe'
else:
ndk_url = ndk_url_base + '-windows-x86.exe'
ndk_bundle = 'android-ndk-' + NDK_VER + '.exe'
to the simpler form:
else:
ndk_url = ndk_url_base + '-windows-x86_64.exe'
ndk_bundle = 'android-ndk-' + NDK_VER + '.exe'
(if it wasn't clear, that meant edit the file in the last line of the traceback, C:\Users\derrick\Desktop\iotivity-2.0.1.1\iotivity-2.0.1.1\extlibs\android\ndk\SConscript)

H2O h2o.importFile Error: 'Cannot determine file type. for nfs://.../model.zip', caused by water.parser.ParseDataset$H2OParse

I am trying to import a h2o model as a .zip file exporter as POJO with R. The following error is all I get:
model_file <- "/Users/bernardo/Desktop/DRF_1_AutoML_20190816_133251.zip"
m <- h2o.importFile(model_file)
Error: DistributedException from localhost/127.0.0.1:54321: 'Cannot determine file type. for nfs://Users/bernardo/Desktop/DRF_1_AutoML_20190816_133251.zip', caused by water.parser.ParseDataset$H2OParseException: Cannot determine file type. for nfs://Users/bernardo/Desktop/DRF_1_AutoML_20190816_133251.zip
I already ran file.exists(model_file) and that returns TRUE, so the file exists. Did the same with normalizePath(model_file) and same result. When I try to import it into my R session, it seems that h2o finds the file but can't import it for some reason.
Here's my R Session info:

Hope you guys can help me import my POJO model into R. Thanks!

h2o models are not zip files. Try this
# path to your file
model_file <- "/Users/bernardo/Desktop/DRF_1_AutoML_20190816_133251.zip"
# prediction based on your mojo/pojo file.
preds = h2o.mojo_predict_df(df, model_file, genmodel_jar_path = NULL, classpath = NULL, java_options = NULL, verbose = F)
If they are zipped, then unzip and run them again. More info is here http://docs.h2o.ai/h2o/latest-stable/h2o-docs/save-and-load-model.html
https://rdrr.io/cran/h2o/man/h2o.mojo_predict_df.html

Ok, I actually found the solution I needed. The trick is to convert your dataframe (df) to json format, and then use the .zip file generated with h2o to predict using the h2o.predict_json instead of h2o.mojo_predict_df. I think it's pretty straight forward and less complicated. At least it worked as I needed it to work.
library(jsonlite)
library(h2o)
json <- toJSON(df)
output <- h2o.predict_json(zip_directory, json)
NOTE: No need to unzip the zip file.
If by any chance you've used the lares package, simply use the h2o_predict_MOJO function.
Hope it helps any other people trying to achieve the same result.

JPype (Python): importing folder of jar's

i am using JPype in order to work with java classes in python.
I have a folder that contains multiple self-written .jar files.
I know how to import multiple .jar's on the long way:
...
CLASSPATH = "/path/to/jars/first.jar:/path/to/jars/second.jar"
jpype.startJVM(jpype.getDefaultJVMPath(), "-ea", "-Djava.class.path=%s" % CLASSPATH)
MYLIB= jpype.JPackage("org").mylib
MyClass = MYLIB.MyClass
myObj = MyClass()
This works fine, but i think there might be a better way.
I already tried this:
CLASSPATH = "/path/to/jars/*.jar"
and this:
CLASSPATH = "/path/to/jars/*"
In both cases following error occurs:
user#user:~/path/to/python/$ python test.py
Traceback (most recent call last):
File "test.py", line 23, in <module>
myObj = MyClass()
File "/usr/local/lib/python2.7/dist-packages/JPype1-0.6.2-py2.7-linux-x86_64.egg/jpype/_jpackage.py", line 60, in __call__
raise TypeError("Package {0} is not Callable".format(self.__name))
TypeError: Package org.mylib.MyClass is not Callable
My Question:
Is there any way to easily import a folder that contains multiple .jar's in JPype?

You can join the list of jar files with Python code without hardcoding
f'{str.join(":", ["path/to/jars/"+name for name in os.listdir("path/to/jars")])}'

Ansible: Changing permission of a directory issue

I'm running the following Ansible task to change permission of a directory and its content.

There are no subdirectories.
Also when I run the command chown -R adrt:adrt . inside the directory /opt/as2/app-server it executes without any issue.
Help me to understand what is happening here.

Help me to understand what is happening here.
You have just found a bug in Ansible which causes modules to fail when the names of files it processes contain $_ sequence.
The name is passed without escaping the $ character (or rather with an explicit conversion request os.path.expandvars(filename)) and the sequence $_ is processed as an built-in variable resolving to the path of the current process (/usr/bin/python in this case, as Ansible uses Python to run its modules).
In result the file name:
As2MetricsService$_$tt__collectStats_closure14.class
is interpreted as:
As2MetricsService/usr/bin/python$tt__collectStats_closure14.class
and the system throws an error that the file does not exist (which is true).
Until it is fixed, I guess you have to call chown with the command module

Using a Python Script in Java (Eclipse)

I've been looking to incorporate a Python Script a friend made for me into a Java application that I am trying to develop. After some trial and error I finally found out about 'Jython' and used the PythonInterpreter to try and run the script.
However, upon trying to run it, I am getting an error within the Python Script. This is odd because when I try run the script outside of Java (Eclipse IDE in this case), the script works fine and does exactly what I need it to (extract all the images from the .docx files stored in its same directory).
Can someone help me out here?
Java:
import org.python.core.PyException;
import org.python.util.PythonInterpreter;
public class SPImageExtractor
{

PythonInterpreter interp = new PythonInterpreter();
interp.execfile("C:/Documents and Settings/user/workspace/Intern Project/Proposals/Converted Proposals/Image-Extractor2.py");
}
catch(Exception e)
{
System.out.println(e.toString());
e.printStackTrace();
}
}
}

My guess is that you don't get command line arguments if the interpreter is called (well not that surprisingly, where should it get the correct values? [or what would be the correct value?]).
os.getcwd()
Return a string representing the current working directory.
Would return the working dir, but presumably that's not what you want.
Not tested, but I think os.path.dirname(os.path.realpath( __ file__)) should work presumably (Note: remove the space there; I should look at the formatting options in detail some time~)
