I am running Windows 7 Professional
I have installed Python 3.6
My version was verified by pip --version to give the following:
pip 9.0.1 from C:\ProgramData\Miniconda3\lib\site-packages (python 3.6)
Using PIP I have installed NumPy and SciPy by the following:
pip install numpy
pip install scipy
I can verify the instalation using pip list to show:
cffi (1.9.1)
conda (4.2.13)
cryptography (1
idna (2.2)
menuinst (1.4.4
numpy (1.12.1+m
pip (9.0.1)
pyasn1 (0.1.9)
pycosat (0.6.1)
pycparser (2.17
pyOpenSSL (16.2
pywin32 (220)
requests (2.12.
scipy (0.19.0)
setuptools (27.
six (1.10.0)
wheel (0.29.0)
In the command prompt I can type python, and then import scipy like so:
C:\Users\james.hayek\Desktop>python
Python 3.6.0 |Continuum Analytics, Inc.| (default, Dec 23 2016, 11:57:41) [MSC v
.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import scipy
>>>
It would appear as if everything has installed correctly. However, when I start IDLE and type import scipy I get the following error:
>>> import scipy
Traceback (most recent call last):
File "<pyshell#8>", line 1, in <module>
import scipy
ModuleNotFoundError: No module named 'scipy'
>>>
Any idea's how I can call/import SciPy in IDLE?
Your Miniconda package has made its own Python SDK default. You need to run your IDLE and add Miniconda's site-packages directory to your regular PYTHONPATH:
import sys
print(sys.path) # to verify that Miniconda is not in this PYTHONPATH
sys.path.append('C:\ProgramData\Miniconda3\lib\site-packages')
To check your path you can equally go to File -> Path Browser

Im runnig a windows 10 machine, and im getting started on playing with virtual enviorments. I want to run a small fastapi application
I created a venv like this:
python -m venv venv
I then activated the venv, and installed my two dependencies:
(venv) PS C:\Users\Ask\python_Projects\garse_dockerAPI\app> pip install fastapi
and
(venv) PS C:\Users\Ask\python_Projects\garse_dockerAPI\app> pip install unicorn
Which seemed to work fine, running pip list also seems to indicate that i have what I need:
(venv) PS C:\Users\Ask\python_Projects\garse_dockerAPI\app> pip list
Package Version
----------------- ---------
beautifulsoup4 4.9.3
certifi 2020.6.20

chardet 3.0.4
crypto 1.4.1
cryptography 3.1.1
cycler 0.10.0
fastapi 0.63.0
idna 2.10
myModule 1.0.0
Naked 0.1.31
pip 21.0.1
pycparser 2.20
pycrypto 2.6.1

soupsieve 2.0.1
starlette 0.13.6
typing-extensions 3.7.4.3
unicorn 1.0.2
urllib3 1.25.10
wheel 0.35.1
But when I run my program it fails with the inmport of the fastapI:
(venv) PS C:\Users\Ask\python_Projects\garse_dockerAPI\app> python .\main.py
Traceback (most recent call last):
File "C:\Users\Ask\python_Projects\garse_dockerAPI\app\main.py", line 3, in <module>
from fastapi import FastAPI
Also, running python my terminal doesnt wanna do it either:
(venv) PS C:\Users\Ask\python_Projects\garse_dockerAPI\app> python
Python 3.9.0 (tags/v3.9.0:9cf6752, Oct 5 2020, 15:34:40) [MSC v.1927 64 bit (AMD64)] on win32

>>> import fastapi
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'fastapi'
What's going on? why do i not have the dependencies i need?
EDIT:
In order to find the installation on my machine, I ran 'where python' in my normal terminal:
C:\Users\Ask>where python
C:\Users\Ask\AppData\Local\Programs\Python\Python39\python.exe
C:\Users\Ask\AppData\Local\Microsoft\WindowsApps\python.exe
Which give sme two different paths. I dont really know what to do with this information?
running where pip:
C:\Users\Ask>where pip
C:\Users\Ask\AppData\Local\Programs\Python\Python39\Scripts\pip.exe
When I run it in my venv, the commands output nothing at all:
(venv) PS C:\Users\Ask\python_Projects\garse_dockerAPI\app> where pip
(venv) PS C:\Users\Ask\python_Projects\garse_dockerAPI\app> where python
(venv) PS C:\Users\Ask\python_Projects\garse_dockerAPI\app>
I definitely recommend using python3 -m pip instead of pure pip. It might save you some headache. The reason: when I used pip to install new packages in a venv virtual environment, they ended up in my OS environment! But just using python3 -m pip did the trick.
To make sure that the packages are called from your virtual environment, you can use python3 -m PACKAGE_NAME instead of PACKAGE_NAME. For example, flower didn't work in my virtual environment, but python3 -m flower works with no problem.
You can directly ask python where it is executed from! Try this:
>>> import sys
>>> print(sys.executable)
/PATH/TO/VENV/bin/python
>>> print(sys.version)

I am trying to use DBUS as the main loop of PyQt5.
System-wide
I installed, system-wide (with apt, LinuxMint 19, amd64), the following dependencies:
python3-pyqt5 Version: 5.10.1+dfsg-1ubuntu2

So it seems the system version is used. Ok.
What am I missing ? Is there a pip package for the dbus mainloop ? Thanks.
edit: So far, I can work with the default
from dbus.mainloop.glib import DBusGMainLoop
DBusGMainLoop(set_as_default=True)
But if Gtk is now a dependency, that isn't satisfactory.
So far, I can work with the default glib mainloop:
EDIT: this won't work on other platforms than Linux (tested with MacOS).
from dbus.mainloop.glib import DBusGMainLoop
DBusGMainLoop(set_as_default=True)
glib is decoupled from Gtk, so it's alright I guess.
I have problems doing import of packages I installed via pip3 in a MinGW environment. The module is not found but it is installed.

I do not understand MinGW but it looks like that Python3 is the default here.
So python is Version 3.7.3 by default.
All PyPi packages I installed with pip3 are able to load via python -m or directly inside the python interpreter shell.
I'm wondering about the following importError which I can't get ride off. I have a local virtualenv (venv) in which I've installed multiple modules:
(venv) stam#stam:~$ pip list --local

cvxopt (1.1.9)
cycler (0.10.0)

You are using pip version 8.1.2, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
(venv) stam#stam:~$
now starting a python interpreter and trying to import cvxopt (note it is in the list above) gives me a importError. Why is this? I'm using the right python version, I work on the venv so everything should work out of the box.
(venv) stam#stam:~$ python

I'm a bit lost and don't know how exactly I can resolve this issue. It seems the right python version is started, at least the one I've attached to the virtualenv.
Additional outps asked for in the comments
(venv) stam#stam:~$ which python
/usr/bin/python
(venv) stam#stam:~$ which pip
/usr/local/bin/pip
Based on the output from which it seems clear that your python and pip belong to two different instances. So all libraries you install will be installed for some other python instance.
The acute fix is to force pip to run through your specified interpreter:
python -m pip list --local
python -m pip install cvxopt
