Anylogic, parameter variation experiment pipeline source error

I am trying to create a parameter variation based on a single python script run using the pipeline jar. I manually added a variable called 'pyCommunicator ' of the type other 'PyCommunicator' with initial value new 'PyCommunicator()'.
In the 'initial experiment set' block of the properties section, I import the python file via 'pyCommunicator.run("import GA");'
However, when I try to run the parameter variation I get the error code "PyCommunicator.java:669' indicating that the source code is not present. It also states '669 is not a valid line number in com.anylogic.libraries.pypeline.PyCommunicator'
When I add the jar file at the 'Change Attached Source' option the error does not change. The jar file is in the same folder as the anylogic and python files. I am not sure why the error occurs now. Has anybody experienced this issue before?
This is what it shows if you click on the error:

Python(on Win10): Path issue replacing "\" with "/"

Preface: I am a beginner to Python
Problem statement: I am writing a script wherein I will be launching an application (Gotit.exe) sitting at particular path lets say D:\Some Folder\SomeMore Folder\AgainFolder\myPythonFolder\Gotit.exe. I have kept the python-script also in myPythonFolder.
I am accessing the folder path via os.path.dirname(os.path.realpath(__file__)) and selecting particular application by appending it with \Gotit.exe but when passing the same appended string stored in a variable i.e. GotitexePath to os.system(GotitexePath) its throwing error as,
'D:\Some ' is not recognized as an internal or external command,
operable program or batch file.**
Kindly help me out to solve the said issue
I am using python 3.8.2 on Win10 Machine

The error is pointing to Some Folder name. Since there is a space in path you provide, the system doesn't know whether it is a part of folder name or it is a next argument to the command.
You need to escape the blank space. There are multiple ways to to it. For example wrap the path with double quotes:
"D:\Some Folder\SomeMore Folder\AgainFolder\myPythonFolder\Gotit.exe"
For more ways see this post

os.system("\"%s\"" % GotitexePath)
A the previous replies say, you need to add additional quotation marks around the path for the windows command line.

ValueError: need more than 0 values to unpack (Python 2)

I am trying to replicate another researcher's findings by using the Python file that he added as a supplement to his paper. It is the first time I am diving into Python, so the error might be extremely simple to fix, yet after two days I haven't still. For context, in the Readme file there's the following instruction:
"To run the script, make sure Python2 is installed. Put all files into one folder designated as “cf_dir”.
In the script I get an error at the following lines:
if __name__ == '__main__':
cf_dir, cf_file, cf_phys_file = sys.argv[1:4]
os.chdir(cf_dir)
cf = pd.read_csv(cf_file)
cf_phys = pd.read_csv(cf_phys_file)
ValueError: need more than 0 values to unpack
The "cf_file" and "cf_phys_file" are two major components of all files that are in the one folder named "cf_dir". The "cf_phys_file" relates only to two survey question's (Q22 and Q23), and the "cf_file" includes all other questions 1-21. Now it seems that the code is meant to retrieve those two files from the directory? Only for the "cf_phys_file" the columns 1:4 are needed. The current working directory is already set at the right location.
The path where I located "cf_dir" is as follows:
C:\Users\Marc-Marijn Ossel\Documents\RSM\Thesis\Data\Suitable for ML\Data en Artikelen\Per task Suitability for Machine Learning score readme\cf_dir
Alternative option in readme file,
In the readme file there's this option, but also here I cannot understand how to direct the path to the right location:
"Run the following command in an open terminal (substituting for file names
below): python cfProcessor_AEAPnP.py cf_dir cf_file cf_phys_file task_file jobTaskRatingFile
jobDataFile OESfile
This should generate the data and plots as necessary."
When I run that in "Command Prompt", I get the following error, and I am not sure how to set the working directory correctly.
- python: can't open file 'cfProcessor_AEAPnP.py': [Errno 2] No such file or directory
Thanks for the reading, and I hope there's someone who could help me!
Best regards & stay safe out there during Corona!!

cf_dir, cf_file, cf_phys_file = sys.argv[1:4]
means, the python file expects few arguments when called.
In order to run
python cfProcessor_AEAPnP.py cf_dir cf_file cf_phys_file task_file jobTaskRatingFile jobDataFile OESfile
the command prompt should be in that folder.
So, open command prompt and type
cd path_to_the_folder_where_ur_python_file_is_located
Now, you would have reached the path of the python file.
Also, make sure you give full path in double quotes for the arguments.

Subversion Hook Script WIndows, Python, pysvn

I'm trying to create a hook script for subversion on windows, I have a bat file that calls my python script but getting the log/comments seems to be beyond me.
I have pysvn installed and can get the transaction like this:
repos_path = sys.argv[1]
transaction_name = sys.argv[2]
transaction = pysvn.Transaction( repos_path, transaction_name)
I can also list what has changed:
transaction.changed(0)
What I cannot figure out is how to get the log/comment for the transaction. I realize that in pysvn there is a command similar to:
transaction.propget(propname,path)
But cannot for the life of me get it to return anything. I assume propname should be "svn:log", for path I have tried the fiel name, the repo path, null but all get are errors.
AT the end of the day I need to validate the comment, there will be matching against external data that will evolve, hence why I want to do it in python rather than the bat file, plus it may move to a linux server later.
AM I missing something obvious? How do I get the log/comment as a string?
Thanks, Chris.

After a great deal of trial and error and better searching after a day of frustration I found that I need to use the revision property, not a straight property, for a given transaction this will return the user submitted comment:
transaction.revpropget("svn:log")
There are other useful properties, this will return a list of all revision properties:
transaction.revproplist()
for example:
{'svn:log': 'qqqqqqq', 'svn:txn-client-compat-version': '1.9.7', 'svn:txn-user-agent': 'SVN/1.9.7 (x64-microsoft-windows) TortoiseSVN-1.9.7.27907', 'svn:author': 'harry', 'svn:date': '2017-12-14T16:13:52.361605Z'}

Python 3 FTPLIB, NoneType Errors, and Uploads/Downloads

In my script I want to be able, in the end, to be able to download all files in a directory and all sub-directories... So I am trying FTPLIB. I'm trying to call dir of my ftp server and put it into a variable, but I get NONETYPE?! I can connect to the server and when I call directory = session.dir() It displays a kind of matrix style output in the console with files, read/write perms, dates, etc.... But when I then try to print Directory all I seem to get is "None". My initial idea was to for each item in the directory download them to my computer, but I can't seem to get a list of the directory!
directory = session.dir()
print(str(directory))
Sorry for the long and probably trivial explanation, but I have become a little bit too frustrated.
Any help would be very much appreciated!

First, read this. http://docs.python.org/library/ftplib.html#ftplib.FTP.nlst
Then, try this:
directory = session.nlst()
print(directory)
Note.
You don't need to do print(str(...)). The print function gets the string representation for you.

In the official docs, the very first example shows how to do what you need: use .retrlines('LIST') to read the output of LIST command.
Another way is to use .nlst().
