Facing ImportError: cannot import name 'ModelParameters' (Python)

I am using the module ydata_synthetic (github link) for generating synthetic timeseries datasets. After installing the package, I ran the following commands:
from os import path
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
from ydata_synthetic.synthesizers import ModelParameters
from ydata_synthetic.preprocessing.timeseries import processed_stock
from ydata_synthetic.synthesizers.timeseries import TimeGAN
I am receiving the following error:
ImportError Traceback (most recent call last)
<ipython-input-11-9f2f25e511c0> in <module>
4 import matplotlib.pyplot as plt
5
----> 6 from ydata_synthetic.synthesizers import ModelParameters
7 from ydata_synthetic.preprocessing.timeseries import processed_stock
8 from ydata_synthetic.synthesizers.timeseries import TimeGAN
ImportError: cannot import name 'ModelParameters'
How can I solve this error?

Please make sure, that the virtual environment, where you installed the package is the same one where you try to execute your code. In case of venv or anaconda, you need to explicitly activate it in the console/terminal, then use pip to install your package and then also use that activated environment to execute your python script. If you are using an IDE, you need to set your IDE python interpreter to that specific new environment you created and installed the packe in.

Unexpected solution I found:
Use Python 3.7 (not 3.6, or 3.8+).
It seems like much of the code requires features that were new to 3.7 (eg namedtuple with default values), but the codebase has not yet been adjusted to run with python 3.8 or later.

How to install sklearn package in Jupyter Notebook in pycharm

I was receiving the following error. I have installed the package in the pycharm. Now the module is available in main.py file but the module is not available in jupyter notebook that I am using in pycharm.
When I run the cell I still get the following error in jupyter notebook but not in main.py file.
Please help me out!

No module named hyppo._utils when importing models

My issue is when trying to import the DCSBM model:
Code:
import matplotlib as mpl
import matplotlib.pyplot as plt
import numpy as np
import seaborn as sns
import hyppo
from hyppo.time_series import _utils as _utils

from graspy.models import SBMEstimator
from graspy.models.sbm import _block_to_full, _get_block_indices
from graspy.simulations import er_np, sbm

NOTE: If your import is failing due to a missing package, you can
manually install dependencies using either !pip or !apt.

"Open Examples" button below.
I think hyppo._utils doesn't exist and has been replaced by hyppo.time_series and inside that folder there exists the required _utils package.
How do we fix this?
I was just trying to run the tutorial: https://docs.neurodata.io/notebooks/pedigo/graspologic/2020/09/24/latent_model_tutorial.html
Run on Google colab
This line
from hyppo.time_series import _utils as _utils was added from me trying to fix the issue, but doesn't work.

Looks like you're using an old version of the package - it's called "graspologic" now. If you pip install graspologic, from graspologic.models import DCSBMEstimator should work fine. Just replace everything in that code that says "graspy" with "graspologic".
we're happy to answer questions on github issues as well! (I'm one of the people who contributes to the package)

No module named 'lib.mouse' - python

I installed the library Mouse in a virtual environment through the conda prompt, and while importing the lib.mouse library, results in an error.

I am assuming you copy your code from https://github.com/dev-labs-bg/football-stats
In the repo, there is a folder called lib. You need to copy that too. It's not part of opencv library, it's a python module from that repo.

How to get matplotlib working in Python3 on OS X?

I am trying to do Google's deep learning course on Udemy. For assignment one I need to verify that the following modules are working on my machine, but can't get matplotlib.pyplot working. The python code I must get to compile is the following:
# These are all the modules we'll be using later. Make sure you can import them
# before proceeding further.
from __future__ import print_function
import matplotlib.pyplot as plt
import numpy as np
import os
import sys
import tarfile
from IPython.display import display, Image
from scipy import ndimage
from sklearn.linear_model import LogisticRegression
from six.moves.urllib.request import urlretrieve
from six.moves import cPickle as pickle
# Config the matplotlib backend as plotting inline in IPython
%matplotlib inline
When I compile and run this like so:
python3.6 nn_assignment_1.py
I get the following error:
Traceback (most recent call last):
File "nn_assignment_1.py", line 9, in <module>
from IPython import display, Image
ImportError: cannot import name 'Image'
Any ideas how to get matplotlib working for python 3 here? I have been banging my head against the keyboard for hours trying to figure this out.
