I have already installed pyscipopt.
I type pip install pyscipopt in command prompt.
I also can run my script using IDLE (Python 3.6 64-bit).
But when I want to run it using command prompt, I got ModuleNotFoundError. It said that "No module named 'pyscipopt'".
You probably have more than one versions in your PC. So when you run pip install,the default version will install pyscipopt instead of 3.6.
Try this:
C:\>path\to\python3.6.exe -m pip install -U pyscipopt

So, I have python 3.9.7 installed.
When I installed it, pip had also been installed.
I checked if python is installed (Windows) using "python --version".
The Problem: When I try the same with pip; "pip --version",
an error occurs saying that the program can't be executed (command prompt)
Does anyone know why?
You can try to reinstall pip. This my solve the issue. Use can either install it over command window with 'py -m ensurepip --upgrade' oder download the 'get-pip.py' file (check https://pip.pypa.io/en/stable/installation/).
Try this first
Did you added python to PATH? This is also important. Check https://datatofish.com/add-python-to-windows-path/ to do so
Make sure that the python version is the version of your intent.
Windows python installer sometimes defaults to py for newer python installations.
python --version
Then try to install for example openpyxl package, with admin access, if required
python -m pip install openpyxl
Have you already tried pip3?
pip3 install openpyxl
I am on a MAC OS 10.15.6
I am having a tough time with virtualenv for python3.
The error I keep getting
ModuleNotFoundError: No module named 'virtualenv.seed.via_app_data'
It pops up when I run the following command (among others)
python3 -m virtualenv
What I have tried
Pip installing virtualenv with sudo
Regular pip install, normal permissions
Using the pip install --user option
Trying older versions of virtualenv (20.0.23)
Trying newer version of virtualenv (20.0.31)
Any leads are appreciated.
Exactly same problem!
I uninstalled virtualenv, and now it works!
pip uninstall virtualenv
I don't know why
Maybe python now comes with a built-in version of virtualenv?
I'm on python 3.8
I am trying to update the module vpython to the most current version. I run:
pip3 install --user vpython --upgrade
in a Jupyter terminal. This gives the error:
ERROR: jupyter-server-proxy requires Python '>=3.5' but the running Python is 3.4.2
But when I run:
python3 --version
it returns:
Python 3.5.2 :: Anaconda 4.1.1 (64-bit)
Is there something going wrong with the installed Python3 kernel for Jupyter?
Change the environmental variable in your control panel just a simple conflict between python 3.4 and 3.5 this will surely solve your issue.
The issue is that you are using pip3 which is not always tied to the specified python you are trying to run. pip is a module installed with each python3 instance, so to specify it to install to a python environment, use the -m flag:
python -m pip install <module>
Where python is the python that you expect. For instance, if you want it to run against the installation that you use through python3, then you would do python3 -m pip install <module>. This makes things easy to track, since if you want to see which python you are installing to, you can use python -m pip -V. On my machine that outputs:
pip 19.3.1 from /Users/mm92400/anaconda3/lib/python3.6/site-packages/pip (python 3.6)
When I try to install Tensorflow by typing "pip3 install --upgrade tensorflow" into the C: command prompt line, I get the error: "pip3 is not recognized as an internal or external command, operable program or batch file" (See attached picture)
I have Python 3.6.5 installed on my Windows 7 laptop, so it includes "pip3" needed to install Tensorflow.
Since your computer does have Python 3.6 and it comes with pip, you could try running
python -mpip install tensorflow
If Python isn't found either, run
c:\python36\bin\python -mpip install tensorflow
The problem here is that "pip3" is not recognized as a command. In order for pip to be run from the command line, it needs to be added to your system's PATH.

I want to use module keyboard in Python 3.5.3.
pip, import and my program work fine on Windows. On my Raspberry pip install works and pip list shows keyboard.
However when I try to run
import keyboard
I get the error:
"ImportError: No module named 'keyboard'"
I even tried to use sudo import as the keyboard documentation suggests with the same result.
What am I missing?
You need to check which interpreter your pip is installing packages to.
You have both Python2 and Python3 installed on your PI, so only one of these will have access to the packages you are installing with pip.
You can check which interpreter your pip is installing packages to by running the following commands:
[root#pi] python2 -m pip list
[root#pi] python3 -m pip list
If pip is installing the packages to your Python2 installation, you will need to explicitly call the Python3 interpreter when installing the packages
[root#pi] python3 -m pip install keyboard
I'm using Python 3.7.3 on Raspberry Pi, now the import keyboard is not longer required, just comment it or remove the line; all must works fine.
