I am trying to learn kivy and create application in it. during the design language in .kv file, I found:

Invalid property name
This ParserError was throwmn by kivy.
The.kv file:
<grid>
Label:
text = 'OOOOoooo'
I am new to kivy and and trying to make an application that I have made in tkinter
You must change to
text: "OOOOoooo"
(Use :, not =).

When I run my program from PyCharm, it runs without any problems. However, when building an exe using PyInstaller I am getting a very strange error, especially as this error message is referencing a line number that does not exist.
Here is the full error message:

The error refers to line 18 in procguides.py, but this line does not exist as you can see in the following code fragment:

Builder.load_string(style)

Also there is no reference to kivymd.button in the procguideskv.py file:

I am using the following packages/versions:
Python 3.9.5
Kivy 2.0.0
kivymd 0.104.2
pyinstaller 4.5.1
pyinstaller-hooks-contrib 2021.2
What am I missing here? What is going wrong?
Thanks in advance for your help. Much appreciated.
Can someone explain why multiprocessing works so weird with kivy?
Minimum example:
from kivy.app import App
from kivy.uix.button import Button
from multiprocessing import Process
class myApp(App):
def f(self):
print('test')
def test(self, caller):
pr = Process(target=self.f)
pr.start()
def build(self):
btn = Button(text='Go')
btn.bind(on_press=self.test)
return btn
if __name__ == '__main__':
myApp().run()
I get the following error:

I just installed Anaconda, but when I start Spyder it displays "An error occured while starting the kernel".
I tried updating everything, and unistalling/reinstalling Anaconda (inspired by what I have seen on other posts), but it doesn't work.
(It doesn't work either if I use the Jupiter or other programs).
Here is the full error message:

I would be very grateful if someone would help me.
So I met someone who was good at this and he solved my problem.
He somehow figured out that there was a problem with my environnement variables.
In the environnement variables, in the system variable PATHEXT, are stored some extensions (.COM, .EXE, .CMD,...) that can be recognized by the system. I had an alien in mine, which was not an extension (in that case, it was "C:/HOME/MinGW").
I deleted it and it worked.
This can be set via Window's configuration pannel -> modify system environnement variable. Then press on "environnement variables". On the "system variable" list, select "PATHEXT" and press "modify...".
(NB: My Windows is in French so the names are translated by myself and may not perfectly match to other languages'Windows)
I have a file global_vars.py that contains file paths saved as variables:
from pandas import Timestamp
final_vol_path = 'datasets/final_vols.csv'
final_price_path = 'datasets/final_prices.csv'
final_start_date = Timestamp('2017-01-01')
with other variables written in a similar fashion. However, the functions that I'm using to read in the data throw a FileNotFoundError when attempting to do the following in file1.py:
import scripts.global_vars as gv
read_data(gv.final_vol_path, gv.final_price_path) # throws FileNotFoundError
read_data('datasets/final_vols.csv', 'datasets/final_prices.csv') # this passes
Additionally, I've checked the file paths, and have gotten the following:
gv.final_vol_path == 'datasets/final_vols.csv' # returns True
gv.final_price_path == 'datasets/final_prices.csv' # returns True
Moreover, the pandas Timestamp object is processed without any problems.
Is there any explanation for why the FileNotFoundError is being thrown when attempting to access the file path as a variable from global_vars.py, but is not thrown when the actual string is passed in?
EDIT: The overall directory structure is as follows:
working_dir
L file1.py
L scripts
L global_vars.py
L datasets
L final_vols.csv
L final_prices.csv
EDIT 2: I added in a try-catch block to ensure the rest of the function doesn't break, not sure if that has affected the traceback, but here's what I get:

FileNotFoundError: File b'datasets/corn_price.csv' does not exist
Problem is the addition of the letter b in front of your file's path.
You get the b because you encoded to utf-8.
Try:
read_data(str(gv.final_vol_path,'utf-8'), str(gv.final_price_path, 'utf-8'))
