Not able to use SMOTETomek or SMOTEENN - Import Module error

I am trying to import the following libraries:
from imblearn.combine import SMOTEENN
from imblearn.combine import SMOTETomek
Unfortunately I am getting an error that says:
ModuleNotFoundError: No module named 'scipy.special.cython_special'
I have also checked on the following link :https://imbalanced-learn.org/stable/install.html and looks like almost every dependency is installed in my environment.
I am also getting the same error while I am importing Random forest classifier
from sklearn.ensemble import RandomForestClassifier
What could be the issue here?

Scitools3 gives a module not found from import statement

According to https://pypi.org/project/scitools3/ importing the module as from scitools.std import * should work, but it gives me an error saying ModuleNotFoundError: No module named 'scitools.std'. I've looked everywhere for a solution and can't find a fix

ModuleNotFoundError: No module named 'copy_reg\r'

I am trying to execute a python code in my Windows Machine where I have imported pickle and I have loaded the file but for some reason, it is giving this error called ModuleNotFound and I don't know what does pickle has to do anything with 'copy_reg\r'
Here goes my code:
from six.moves import cPickle
def openfile(basename):
with open(os.path.join(DIR_PATTERNS, basename), 'rb') as fh:
return cPickle.load(fh)
#return open(os.path.join(DIR_PATTERNS, basename), 'rb')
HAVE_FSAs = openfile("HAVE_FSAs.pickle")
Here goes the error:
HAVE_FSAs = cPickle.load(openfile("HAVE_FSAs.pickle"))
ModuleNotFoundError: No module named 'copy_reg\r'
I have already tried import pickle as cPickle but it did not work for me. All the variables are declared so it can't be that as well and moreover, I do not understand why is it giving ModuleNotFound
python3 have copyreg, no copy_reg . so you can correct Source Code, for example, you need delete code:
import copy_reg
then, you must replace:
import copyreg

Yolo-v3 object detection with python

I'm trying to detect objects using Yolo-v3 referring this tutorial. I have already installed darknet.
When I tried to run the following code:
from darknet import Darknet
it says:
ImportError: cannot import name 'Darknet' from 'darknet' (unknown location)
so I tried:
import darknet as dn
net = dn.load_net("cfg/tiny-yolo.cfg", "tiny-yolo.weights", 0)
then it says:
"AttributeError: module 'darknet' has no attribute 'load_net'"
How I can avoid these errors?
Use it like this.
import cv2
import matplotlib.pyplot as plt
from utils import *
from darknet import Darknet
net = Darknet("cfg/tiny-yolo.cfg")
net.load_weights("tiny-yolo.weights")

Trying to import winsound

When I import winsound and then try to run the program, it returns an error message saying:
ImportError: No module named 'winsound'.
Are there any settings I need to change?
winsound only exists in Python installed under Windows. Do not attempt to import it if you are not running under Windows.
