Eclipse Plugin + Jython - Unhandled event loop exception - python

Just in case anybody else tries to use Jython inside a self-build eclipse-plug-in. I suffered 2 days on the following error, which occured as soon as I try to import my python scripts via interpreter.exec("from myScript import *\n");:
!ENTRY org.eclipse.ui 4 0 2015-12-11 11:22:53.549

AttributeError: 'NoneType' object has no attribute 'endswith'

It is needed to set the property python.home to some value. It looks like it does not even matter which value .. it just is not ok to leave it empty.
Setting the property e.g. can be done in the java-code:
String jythonJarPath = "target/lib/jython-standalone-2.7.0.jar";
String pythonLibPath = SilecsUtils.findInBundle(jythonJarPath);
Properties sysProps = System.getProperties();
sysProps.setProperty("python.path", pythonLibPath + "/Lib");
sysProps.setProperty("python.home", ".");

Numpy is Not a Generic Class

I am trying to learn Python and following along some modules. I am using Anaconda Powershell Prompt and using Python 3.7 from there. I am trying to follow along via the code below.
Everything works until I get to the line
from wrf import getvar
When I do that line I receive this
>>> from wrf import getvar

TypeError: <class 'numpy.typing._dtype_like._SupportsDType'> is not a generic class
Looks like the last few lines return an error but as a beginner I have zero clue what this means.
This looks like a similar error to <class 'numpy.typing._dtype_like._SupportsDType'> is not a generic class when importing the plotly.express library - an incompatibility between wrf-python and numpy.
Try upgrading those libraries to the latest versions.

Checkov error: AttributeError: type object 'Lark' has no attribute '_load_from_dict

I'm having some issues running checkov, I'm not familiar with python libraries, anyone can give me some hints?
This is working fine in some machines but not in this one in particular...

AttributeError: type object 'Lark' has no attribute '_load_from_dict'
After upgrading python from 3.6 to 3.8 and reinstalling checkov it worked just fine.

Simple code for create a thread in Python 2.7

I'm new to Python and I'm trying to do a simple thread as follows.
import threading
def func(x):
print x
t1 = threading.Thread(target=func,args=("Hello",));
t1.start();
Then I got following error:

can someone help me to understand this error?
/Users/treinetic-macbook/Desktop/threading.py is being imported because it's on your path somewhere. This is most likely not correct, try renaming that file and removing any threading.pyc file in your local dir.

have been fighting with this without progress for 2 days now.. if somebody could givme somekind of insight or advice i would be more than happy!
Found the solution, it was problem in the data parsed to the tool, not the tool itself.
