python3.4 on raspberry pi 3 cant find cv2 module - python-3.x

I tried to install opencv2 to my raspberry pi 3 following this tutorial
pyimagesearch.com
,I made it to the end. But when I tried to run a program, it shows ImportError : no module named 'cv2' as in this picture screenshot.
The program is running well on python2.7.9, but why it pop that error in python 3.4? How can I fix this error? If anyone can help me it would be much appreciated, because I need that program to run in python3.4. Thank you

I fixed my own problem haha.. All I need is to copy cv2.so from /usr/local/lib/python3.4/dist-packages/cv2.so to /usr/lib/python3.4/cv2.so .... Tried my program after that, then it worked as good as in python2.7

Python Module not found, but it is installed?

I wanted to make an Instagram bot so I can automate my posts and whatever. My problem is, I get the following Error when I try importing the module/library named "instagrapi":
Exception has occurred: ModuleNotFoundError
No module named 'instagrapi'
File "C:\Users\Simon\Desktop\Py\bot.py", line 1, in <module>
from instagrapi import Client
the error is in line 1 of my code, which simply states "from instagrapi import Client"
Now to my question: I already installed instagrapi, but VSCode tells me I didn't. I installed Python 3.11 but it runs in 3.10 or what so ever.
If someone can help me, please do so, thanks in advance
I tried reinstalling the library and restarting vscode, but it didn't help.
I'm running out of ideas

Does anyone know how to make python go to the system default tk installation (on Linux) for the tkinter install in the make/configure process

So I have been trying to install Python3.9 with tkinter for a bit now and I have finally come up with a mediocre solution with one problem which is I can't figure out how to make python use the tk8.6-dev package on Debian to install the _tkinter module.
Edit 2 hours later: Figured out answer to first problem. Now need help finding out how to make python successfully find the tcl.h file in /usr/include/tcl8.6/tcl-private/generic/
and the tk.h file in
/usr/include/tcl8.6/tk-private/generic/.

Why am I getting ModuleNotFoundError: No module named 'dpkt'?

When I run
import dpkt
It gives
ModuleNotFoundError: No module named 'dpkt'
But I already installed dpkt.
install dpkt cmd
Does anyone know how I can fix this?
I am using window10, python3.
I had the same issue today. I found out that when I installing the dpkt module, it was getting installed onto an environment different than the one I was using in pyCharm.
I found the answer to this post very helpful to explain my issue: https://stackoverflow.com/a/52608375/2411380
I fixed my issue by using the terminal inside pyCharm to install dpkt, then it worked.
I also found a suggestion to use all packages installed in conda inside pyCharm: https://stackoverflow.com/a/49097897/2411380

Beginner having a problem with matplotlib

I am using the book Python Crash Course as a textbook. I was doing pretty well until I tried to use the Matplotlib library. The book gave the following command to install the library:
python -m pip install --user matplotlib
I entered this in the terminal window in Pycharm (the IDE I am using). It appeared to work, in that I got a series of messages indicating that files were being downloaded and installed on my computer. However when I attempted to import matplotlib.pyplot into an example piece of code I was trying to write, I got a ModuleNotFoundError: No module named 'matplotlib'
I assumed that the downloaded module went to the wrong directory, so I searched my hard drive to find a file or folder named matplotlib. I found several folders in different locations, but when I tried copying them into folders where I knew Pycharm could find it, it didn't seem to help. Can someone please clue me in to how I can use this module.
I am using windows 10 on an MS Surface 6.

PyCharm 2017.1, No module named 'kivy'

I could use (troubleshooting)help with getting Kivy imported in PyCharm. I am using:
Anaconda with Python 3 on 64-bit Windows 10 Pro
PyCharm 2017.1
Packages: NumPy, SciPy, BeautifulSoup, Pandas, Scrapy, Pattern, NetworkX, NLTK, scikit-learn, Selenium
I have installed Kivy following the instructions at https://kivy.org/docs/installation/installation-windows.html#installation
As evident from the screen shot, no errors occurred.
Still, when I run "import kivy" from PyCharm I get "ModuleNotFoundError: No module named 'kivy'".
I ran through the installation with someone on the #kivy channel and was assured that kivy is successfully installed.
When I pass import kivy; print(kivy.file) to the interpreter (opened from the CMD command line), I get returned among others:
C:\Users\Steve\Anaconda3\lib\site-packages\kivy\__init__.py
Someone on #kivy suggested I check where PyCharm looks for kivy. How do I figure that out?
I'd appreciate any suggestions to identify the problem / resolve my issue.
Indeed, the installation of Kivy went fine. The problem turned out to be that I had to select the correct (updated) interpreter in the PyCharm settings.
