Using pyheif in Windows: Missing _libheif_cffi module - python

I'm trying to use pyheif in Windows. For that, I've tried following this solution, provided Yienschwen.
It worked so far as I was able to run pip install pyheif without any problem.
However, now, I'm trying to import pyheif, and I get the following error:
I can't find that file anywhere on the internet...

Using PIP3 to install Pyautogui package but still getting this error - No module named 'pyautogui' (Python)

I am using a windows system and I have no idea why after I use the command "pip3 install pyautogui" it installs successfully however when I click the play button in VS code it gives me an error in the terminal -
ERROR
import pyautogui
ModuleNotFoundError: No module named 'pyautogui'
I am a pure beginner to Python so I have no idea what might be causing this issue. My code is below:
CODE
import pyautogui
screenWidth, screenHeight = pyautogui.size()
print(screenWidth)
print(screenHeight)
Any idea what I can do to solve this? I have checked similar questions but the answers were targeted more towards Linux users.
sometimes pip can have problems with certain libraries.
to get around this, you should download the .whl or tar.gz file and install it directly from there.
this is the .tar.gz file for pyautogui: https://files.pythonhosted.org/packages/f0/76/7a0ec1013bc3559b7438f6773cba05ffaec600b8989be2d621a144e39b50/PyAutoGUI-0.9.53.tar.gz
download it and put it in your project directory.
then, just pip install {THE FILE NAME}.
for me that fixed it.

Windows - PyAudio and PortAudio do not work even after they were installed

I'm trying to make a voice-chat program, trying to use PyAudio since it is one of the more popular modules to work with when you try to make a voice chat program, plus more sources if I'll need help. Tried to download PyAudio with PipWin, tried to run it and it gave me the error message:
import _portaudio as pa
ModuleNotFoundError: No module named '_portaudio'
Now I downloaded the PortAudio tgz file from the download website and extracted it, but I cant seem to see how to make it work out with pyAudio. Also tried to use conda to install PyAudio but I can't seem to find where it put the file in, even when I search in the Anaconda3 folder.
I use Windows.
Did anyone have the same problem and if so how did you solve it?

Trying to import GitHub module

I'm trying to import https://github.com/chrisconlan/algorithmic-trading-with-python in my code. I've never imported anything from GitHub before and have looked at various other questions that have been asked on Stack Overflow regarding this problem but it just doesn't work. When I try to run the 'portfolio.py' code for example I keep getting a ModuleNotFound error for 'pypm'. What exactly is the correct way to import such a module or the whole GitHub directory?
I'm working with Visual Studio Code on Windows.
You will need to pip install the module. In your case the command you would need to run is python -m pip install -U git+https://github.com/chrisconlan/algorithmic-trading-with-python. Once you have done that you need to find the name of the module. You can do this with pip list. Find the name of the module you just installed.
Then you just stick import <module name> at the top of your code with the rest of your imports.
What i used to do in this is to clone the repository on the folder where are installed the python's packages. This is useful when you do not want to use the pip cmd tool, keeping the pip's cache memory under control.

Downloaded package ImportError

I have recently installed python 2.17.14 to use a package which I installed in the command prompt with:
python -m pip install packageName
However, whenever I try to use it with a script provided by the package authors, I get Import Errors:
ImportError: cannot import X from YX
ImportError: attempted relative import with no known parent package.
I don't know what I'm doing wrong, as I am really new to Python. Does anyone have any ideas?
The package is called neurodesign and I downloaded the try out script from the official website "neuropowertools.org"
Best,
Max
In case anyone (who is also new to python^^) fails ridiculously at this task as well: I had to manually install all the modules used within this package for it to work as they weren't installed automatically.

How do I install the Pygraphics module

I am trying to download the Pygraphics module using Python 2.7.6 and have been heretofore unsuccessful. Below I detail the steps I have taken so far. Any help with this would be most appreciated.
First, I tried the typical install using pip
sudo pip install Pygraphics
When I try to import the module, I receive an error saying ImportError: No module named Pygraphics.
To test whether the module was installed I ran the following code: print sorted(["%s==%s" % (i.key, i.version) for i in pip.get_installed_distributions()]) which showed me all of my installed distributions.
This code returned the following list of all the distributions and clearly showed that Pygraphics is installed:
['altgraph==0.10.2', 'bdist-mpkg==0.5.0', 'bonjour-py==0.3', 'brewer2mpl==1.4', 'certifi==14.05.14', 'datetime==4.0.1', 'flask==0.10.1', 'ggplot==0.6.5', 'ipython==2.0.0-dev', 'itsdangerous==0.24', 'jdcal==1.0', 'jinja2==2.7.3', 'macholib==1.5.1', 'markupsafe==0.23', 'matplotlib==1.4.x', 'mock==1.0.1', 'modulegraph==0.10.4', 'nose==1.3.4', 'numpy==1.9.0.dev-297f54b', 'openpyxl==2.1.2', 'pandas==0.14.1', 'pandasql==0.6.1', 'patsy==0.3.0', 'pika==0.9.14', 'py2app==0.7.3', 'pygments==1.6', 'pygraphics==2.1']
After this, I tried using the GUI installer located on the following Pygrahpics install website. While going through the installer, I received an error message saying "PyGraphics requires System Python 2.7 to install" despite the fact that I have downloaded Python 2.7.6.
At this point I don't know what to do and was hoping someone who may have had a similar issue might be able to help me out.
Thank you for your time.
It looks like you've successfully install PyGraphics. Now import picture :)
