AttributeError related to multiprocessing when using extract_features from tsfresh - python

I have a data frame which contains multivariate time series data. It has columns: fundId (each entity), periodId(time stamp), v1, v2, v3 ...
I want to extract features from those times series for each fund over time. Like: fundId v1.max, v1.min, v1.median, ..., v2.max, v2.min, v2.median, ...
I encountered an AttributeError when use function extract_features from library tsfresh. I'm new to Python but I think it might related to multiprocessing.
The trackback shows:

SyntaxError: invalid syntax
I tried to add parenthesis. I tried to add underscore to the strings. It still did not work.

I was running a script to get data from excel for over a year using the Xlwings range command like so...
list=Range('A1:D10').value
Suddenly, it stopper working. I had changed nothing in the code nor the system, other than maybe installing another network card.
This is the error when trying to use the Range assignment now.

I created a small program that uses numba on a method containing a 2D array (list of lists). This program runs just fine on Spyder, but when I try to run the exact same program on a remote Ubuntu server, I get a long error saying "unsupported nested memory-managed object" (listed below the program code).
The code:
from numba import jit
#jit(nopython=True)
def test():
num1 = 10
num2 = 5
array = [ [ 1 for i in range(num1) ] for j in range(num2) ]
#array = [2 for i in range(num1) ]
sum = 0
for i in range(0,num1):
for j in range(0,num2):
sum = sum + array[i][j]
print(sum)
test()
The error:

I have seen elsewhere that numba doesn't like 2D arrays and lists of lists because of memory. Is there a way to make it work on the remote server, since it works on Spyder? What is it that Spyder does differently to make it work?

this is my error. I don't know what's my error is. And I really do not know what to do right now. I am using PyTorch-lightning with tensorboard. I do not where this error comes from, I can provide more details if you ask. I delete several error information because StackOverflow doesn't allow me to post so much code.

I'm trying to compile a simple standalone python application using Nuitka. I was able to do this using just the standard library.
I'm now looking to bring in some extra dependancies but I am now receiving errors from Nuitka I'm unable to interpret.
I've tried to import numpy into the project which looks like:
Structure:
npg
__init__.py
__main__.py
Pipfile
Pipfile.lock
Here's the __main__.py
import numpy as np
def main():
print('hello Nuitka')
print('hello numpy', np.__version__)
if __name__ == '__main__':
main()
I then run python -m nuitka npg/__main__.py --standalone and get the error:
