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

But when I run my program it fails with the inmport of the fastapI:

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:

>>> 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)
'3.10.5 (main, Jun 6 2022, 18:49:26) [GCC 12.1.0]'

Following this post I created an environment for pypy2.7: conda create -c conda-forge -n pypy2.7 pypy2.7. In the new environment I can now do
$ python -c "import sys; print(sys.executable)"
/usr/bin/python
and
$ pypy -c "import sys; print(sys.executable)"
/home/julian/miniconda2/envs/pypy2.7/bin/pypy
So there is no python in the environment, therefore the system's python gets used, but there is pypy im the environment, which is exactly what we want. Obviously if I try to

According to the post mentioned earlier, I should now be able to conda install numpy, however this will do:
conda install numpy

Notice the python conda-forge/linux-64::python-3.9.2-hffdb5ce_0_cpython, so instead of installing numpy to pypy, it installs a new python3.9.
And sure enough after the numpy installation I get
$ python -c "import sys; print(sys.executable)"
/home/julian/miniconda2/envs/pypy2.7/bin/python
and numpy is still not installed for pypy.
How do I get conda install to work on pypy instead of python?
All of this is happening on the WSL (Ubuntu 18.04).
conda does not support pypy2.7
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 tried to install pip from PyPi

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 want to start with I am new to the python language and am learning on my own. My issue is that I am installing the modules that I'm trying to use. The installs are successful but do not exist when I try to import them. I am using Visual Studio Code, Python 3.6, and Anaconda on Windows 10.
I am trying to use pyttsx3, SpeechRecognition and pocketsphinx.
$pip list
This gives me a very large list but does not contain either of my installed modules.
$python -m pip list
Gives me smaller output with them.

I am fine with this being something small on my part due to my lack of knowledge with this language, but I have done a full days worth of research trying to solve this myself.
Edit:
$pip --version
pip 9.0.1 from C:\Users\Keiro\Anaconda3\lib\site-packages (python 3.6)
You have two versions of pip perhaps two different installations of python as well. One with Anaconda and other one by main site.
Stick to one version and if you install in that use that environment in Visual Studio(Or VS Code)
You have installed those in anaconda which the standard installtion of Python wont recognize..
Open Python prompt from Anaconda Navigator >> Choose the environment (Select base for default) >> Open with Terminal [Or Open with Python]
>>python
>>import pyttsx3
In Visual Studio code set the same environment
Ctrl+Shift+P >> Select Python interpreter
Choose the anaconda location.
Volla. Now it should work
I had the same problem and found the answer in an old forum.
Write "pip3" instead of "pip".
So the code is:
pip3 install pyttsx3
(Source: bash: pip: command not found)
I'm wondering about the following importError which I can't get ride off. I have a local virtualenv (venv) in which I've installed multiple modules:
(venv) stam#stam:~$ pip list --local
cryptography (1.5.2)
cvxopt (1.1.9)
cycler (0.10.0)
Cython (0.25.1)
matplotlib (1.5.3)
more-itertools (2.2)
ndg-httpsclient (0.4.2)
numpy (1.11.2)
pandas (0.19.0)
paramiko (1.15.2)
Pillow (2.8.1)
pip (8.1.2)
psycopg2 (2.6)
python-apt (0.9.3.12)
python-dateutil (2.5.3)
python-debian (0.1.27)
scipy (0.18.1)
setuptools (28.6.1)
simplejson (3.8.2)
urllib3 (1.9.1)
wheel (0.24.0)
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
Python 2.7.9 (default, Aug 13 2016, 16:41:35)

>>> import cvxopt
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named cvxopt
>>>
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
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

>>> 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
