No module named 'PyEmu

No module named PyEmu
PIP:
C:\Users\TEST\Desktop\New folder>pip install pyemu
Requirement already satisfied: pyemu in c:\python37\lib\site-packages (1.2.0)
Installed pyemu still showed this error

It's best to work in a virtual environment. So you can know the problem and work in a more orderly way.
You can create a virtual environment in Windows with virtualenv:
virtualenv envname -p python3
Then you must activate it:
envname\Scripts\activate
Then, install your packages in isolation. If you're still getting errors, you may need to install older versions of the package (and update this issue with your code).

"No module named 'sympy'" Error. Problem occurs after installation

I am new to Python.
I am trying to use the Sympy package.
I am running Python 3.11 in Pycharm
I am using Windows 10.
It displays:
ModuleNotFoundError: No module named 'sympy'
I ran pip install sympy, it installed it. And when I try reinstalling it, it displays:
Requirement already satisfied: sympy in c:\users\jrk\appdata\local\programs\python\python311\lib\site-packages (1.11.1)
Requirement already satisfied: mpmath>=0.19 in c:\users\jrk\appdata\local\programs\python\python311\lib\site-packages (from sympy) (1.2.1)
I tried going through this guide
https://bobbyhadz.com/blog/python-no-module-named-sympy
but it did not work.
I tried uninstalling it and reinstalling it
both with pip and mpip
it unfortunately didnt work
at the top you can see which interpreter i am using
I can see that there is a file called sympy in my downloads folder, maybe that has to be relocated, but where to?

My instructions might be a bit rusty as I don't regularly use Windows for Python but here goes:
You'll notice that the path to your Pycharm Python interpreter (c:\Users\jrk\PycharmProjects..) is different than the path reported by pip in your error messages (c:\Users\jrk\appdata..).
It's perfectly normal to have multiple versions of Python around, but you'll need to be a bit careful about which one you're invoking.
It's unclear from your description where exactly you are running the pip commands, but usually if you open built-in terminal in Pycharm, it most likely has the right virtual environment activated automatically. The command line prompt should begin with (venv) if that is the case. If you then run pip install sympy you ought to have it installed in the correct place.
If you're using a regular command prompt, you can also manually activate the virtual environment by running the activate or activate.bat file that you'll find in c:\Users\jrk\PycharmProjects\pythonProject\venv\Scripts\ folder.
Might want to also read a bit about virtual envs # https://docs.python.org/3/library/venv.html

I found the solution. I do not know why it worked. But i moved the project from the local file on my computer to the server we use in our company, and then it worked

Try Uninstalling it and reinstalling
pip uninstall sympy
pip install sympy

pip3 installs modules to location python3 can't find

I have pip3, installed via the yum install of python3-pip.
I've done a pip3 global install of some modules I need, but python3 can't find them to import. After a little investigation I see that pip3 installed the modules to /usrlib/python3.6/site-packages/pip/_vendor/
The problem is that python3 doesn't seem to know to look at pip/_vendor, it only finds modules directly installed under site-package. If I just copy the modules from .../site-package/pip/_vendor to .../site-package everything works fine.
The issue doesn't appear to be related to file permissions or ability to read the modules.
I'm wondering how I configure either pip to install directly to site-package or python3 to understand how to look in the pip/_vendor location.
I'm configuring this all with ansible and would like as module an option as possible. For instance I could manually use an argument to tell pip3 to install to the folder I want, but I don't want to hardcode the exact site-package directory if I don't have to.

I recommend starting over with pip by downloading and running get-pip.py. This will not only install the latest version of pip, but it will also install packages to a Python-readable location (the version of Python you use to run get-pip.py).
As an aside, I would avoid installing packages system-wide unless there is a specific need for them. At the very least, you should be installing them as a regular user, and even better you should be using a virtualenv.

Python not installing packages in venv, although it is activated

I have my venv activated but still pip installs packages in another folder.
(venv) C:\Users\JB\PycharmProjects\Flask_project>pip install marshmallow
Requirement already satisfied: marshmallow in c:\users\JB\documents\anaconda\lib\site-packages (3.10.0)

My guess is that you are using a command that changes the location of your instalation directory. Another thing I can assume from the problem you are having is that the packages are already installed on your venv, can you please test it ?

Okay, the problem was I had some manual packages which were imported, and was causing problem, creating another venv solved the problem.

How do I install a pip package globally instead of locally?

I am trying to install flake8 package using pip3 and it seems that it refuses to install because is already installed in one local location.
How can I force it to install globally (system level)?
pip3 install flake8
Requirement already satisfied (use --upgrade to upgrade): flake8 in ./.local/lib/python3.4/site-packages
Please note that I would prefer a generic solution (that should work on Debian, OS X maybe even Windows), one that should be used on any platform so I don't want to specify the destination myself.
For some weird reason it behaves like I already specified --user which in my case I didn't.
The only way I was able to install a package globally was to first remove it and install it again after this. Somehow it seems that pip (8.1.1) refuses to install a package globally if it exists locally.
Disclaimer: No virtual environments were used or harmed during the experiments.

Why don't you try sudo with the H flag? This should do the trick.
sudo -H pip install flake8
A regular sudo pip install flake8 will try to use your own home directory. The -H instructs it to use the system's home directory. More info at https://stackoverflow.com/a/43623102/

Maybe --force-reinstall would work, otherwise --ignore-installed should do the trick.

Where does pip installations happen in python?
I will give a windows solution which I was facing and took a while to solve.
First of all, in windows (I will be taking Windows as the OS here), if you do pip install <package_name>, it will be by default installed globally (if you have not activated a virtual enviroment).
Once you activate a virtual enviroment and you are inside it, all pip installations will be inside that virtual enviroment.
pip is installing the said packages but not I cannot use them?
For this pip might be giving you a warning that the pip executables like pip3.exe, pip.exe are not on your path variable.
For this you might add this path ( usually - C:\Users\<your_username>\AppData\Roaming\Programs\Python\ ) to your enviromental variables.
After this restart your cmd, and now try to use your installed python package. It should work now.

For windows 10:
Installing Python for all users is straight forward since when you install you have to click a checkbox for all users.
In order to install modules globally under C:\Program Files\Python310\Lib\site-packages
start CMD prompt as administrator and then install modules
python -m pip install selenium

For the Windows case:
Are you using virtualenv? If yes, deactivate the virtualenv. If you are not using a venv, the package should have already be installed on system level (system-wide). In that case, try to upgrade the package.
pip install flake8 --upgrade

I actually don‘t see your issue. Globally is any package which is in your python3 path‘s site package folder.
If you want to use it just locally then you must configure a virtualenv and reinstall the packages with an activated virtual environment.
