Unable to import Preprocesing python - python

I am using spyder Anaconda. I am unable to import
from preprocessing import parse_annotation,BatchGenerator
I tried to install preprocssing using,
pip install preprocessing
got following error,

what is the best way to solve some Python packages that could not installed by conda

Recently I am facing a embrassing problem is that some Python packages must install using pip. I have read the pip and conda difference:
What is the difference between pip and conda?
I think many people facing the same problem that when you choose conda, then some package could not using conda install, when you use pip install the pacakge, it could not imported into the local project because the project only could import pakcage installed by conda install command. For example I want to use eyeD3 to read the mp3 meta data, but the package could not installed by conda, I installed the package using pip but could not import in the PyCharm IDE. What is the best way to solve this conflict? Am I missing something? Or I have to switch to pip? is it possible to make conda could install package from pip? Any suggestion is welcome, I want to fetch a guidline. I have tried install package like this in the macOS Big Sur:
/usr/local/anaconda3/envs/pydolphin ⌚ 22:20:21

still could not import this pakacage in the PyCharm IDE. I could found the package from the env:
/usr/local/anaconda3/envs/pydolphin/lib/python3.9/site-packages/eyed3

pytorch,opencv installation problem in python2 having cv library installed in python3

i needed opencv libarary for the code so i installed opencv using python3
pip3 install opencv-python
but the code requires and compatible with python 2
so i tried to install the library using just pip instead of pip3
when i tried to install opencv using pip it is saying

You are troubleshooting with your versions. You say your code is not workable for python3 so you tried to run it on python2. It seems that your pip is linking against your python 3.6 Version instead of python 2.X. The best way to handle these problems are virtual environments:
Python 3.X: https://docs.python.org/3/library/venv.html
Python 2.X: https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/
Inside an activated Environment the command python and pip are linked to the version of the environment.

ModuleNotFoundError on virtual env Jupyter lab

I have created a virtual env and installed Jupyter notebood and jupyter lab
after import pandas I get ModuleNotFoundError: No module named 'pandas'
doing the same operation with jupyter notebook does not give me an error, which run in the same venv
I installed pandas into the venv, but got the same error
importing the native python modules works fine
inserting !pip install pandas in an empty cell above returns
Requirement already satisfied: pandas in /home/curwin/jupyterlab/venv/lib/python3.8/site-packages (1.1.3)

I have install a kernel inside the venv with
ipython kernel install --user --name=.venv
and running notebooks from this kernel solved the problem

Importing matplotlib gives error even though installed

I was hoping someone could help me out.
System is MacOS Catalina.
Python 3.8
IDE: VS
I installed matplotlib using pip install matplotlib which I saw stuck in under python2.7. I uninstalled matplotlib and reinstalled it using pip3 install matplotlib and received the following message:

Requirement already satisfied: setuptools in /usr/local/lib/python3.7/site-packages (from kiwisolver>=1.0.1->matplotlib) (46.0.0)
However, when I try to run my .py file with 'import matplotlib' it gives this error:
import matplotlib as mpl
ModuleNotFoundError: No module named 'matplotlib'
I've tried searching different sources for the solution but I am now stuck.
You are mostly running your python script with the command python your_file.py, try running as python3 your_file.py in your terminal. pip3 installs packages under python3, not the default python2.
This is because I believe your mac terminal uses python 2.x by default, therefore the command python uses python 2.x version and python3 uses 3.x version that is available to execute the files. So if you want to install any packages under python 2.x you use pip as the command and to install packages under python 3.x you use pip3 as the command

Enable jupyter widgets

Button(description='Click Me!', style=ButtonStyle())
The text :
Button(description='Click Me!', style=ButtonStyle())
is rendered instead of a UI button
Is another library required ?
From http://ipywidgets.readthedocs.io/en/latest/user_install.html :
Question: When I display a widget or interact, I just see some text,
such as IntSlider(value=0) or interactive(children=(IntSlider(value=0,
description='x', max=1), Output()),
_dom_classes=('widget-interact',)). What is wrong?
Answer: A text representation of the widget is printed if the widget
control is not available. It may mean the widget JavaScript is still
loading. If the message persists in the Jupyter Notebook or
JupyterLab, it likely means that the widgets JavaScript library is
either not installed or not enabled. See the installation instructions
above for setup instructions.
Page refresh fixed issue for me. I think installs referred to in my question were still required.
In my case I had to run again the cells in the jupyter notebook. In the tab Widgets, selecting Save Notebook Widgets State should render the widgets everytime you open the notebook again, without having to re run it.
