I have some difficulties trying to install Scipy for Python 3.5 on a Windows 10 machine and I hope I can find some help here. So here is what I have done so far.
I have downloaded the numpy+mkl for python 3.5 and 64bit version as well as the scipy0.18.1 for the same versions, from Gohlke's website
I installed the numpy+mkl whl with:
python -m pip install numpy-1.11.2+mkl-cp35-cp35m-win_amd64.whl
all goes well.
then I install the scipy package the same way like:
python -m pip install scipy-0.18.1-cp35-cp35m-win_amd64.whl
This also completes.
However, when I try to run python afterwards I get the following error:
Fatal Python error: Py_Initialize: can't initialize sys standard streams
Traceback (most recent call last):
File "C:\Python35\Lib\site-packages\scipy\io\__init__.py" , line 97, in <module>
File "C:\Python35\Lib\site-packages\scipy\io\matlab\__init__.py", line 13 in <module>
File "C:\Python35\Lib\site-packages\scipy\io\matlab\mio.py", line 8 in <module>
ImportError: No module named 'numpy'
I also get a pop-up that Python has stopped working.
I have tried a different order in which I installed the packages, but all lead to the error mentioned when Scipy is installed.
I also installed did this on a windows 7 machine and there it works.
Does anybody have any idea what causes this issue?
I also had some issues. So I just installed Anaconda3 insted of python directly.

I just installed Python 3.9 with the Windows 64-bit installer. For some reason the all of the modules I had previously installed using pip will no longer import, unless I am running Python from the directory where they are located: C:\Users\<user>\AppData\Local\Programs\Python\Python38-32\Lib\site-packages
I tried uninstalling/reinstalling the requests module with pip and then importing requests in a shell, still not recognized.
>>> import requests
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'requests'
I imagine this is probably some environmental variable path issue. I'm new to Python, any help getting this straightened out much appreciated.
Each version of python has its own global sites package directory where it stores the packages you install.
Ex: Python 3.8 will store under %appdata%\Local\Programs\Python\Python38-32\Lib\site-packages
Python 3.9 would store it in a different location (like Python39-32)
In order to install a package for specific version of python you need to install it with python version command.
py -3.9 -m pip install requests
You can refer the official documentation here
I recently got into development with Python running on WSL (Ubuntu 18.04 LTS).
I followed the documentation from here and I'm able to run simple python scripts.
I started playing around with libraries that I installed using the pip3 command such as numpy and pandas and these work fine.
The problem arises when I try to use the statsmodels package.
I've installed it using pip3 install statsmodels
I can see the package in /home/username/.local/lib/python3.6/site-packages/statsmodels I can even see the api.py file in that directory, however, when I type import statsmodels.api as sm as recommended on the statsmodels website I get:
Console output:
username#DESKTOP-1JP4BIE:/mnt/c/users/username/dev/project/playground$ python3 statsmodels.py
Traceback (most recent call last):
File "statsmodels.py", line 5, in <module>
import statsmodels.api as sm
File "/mnt/c/username/chris/dev/project/playground/statsmodels.py", line 5, in <module>
import statsmodels.api as sm
ModuleNotFoundError: No module named 'statsmodels.api'; 'statsmodels' is not a package
I've tried uninstalling and reinstalling (did not work)
I really can't see anything that differentiates this package from the others that I've installed. Does anyone have any insights?
Thanks #Vorsprung durch Technik
The issue was that my file name was statsmodels.py.
I'll remember to be more careful when naming my python files.
I use QGIS 3.6 and Python 3.7 and I try to install a package with pip in command line tool under Windows 7 but I have the following message :
Fatal Python error: initfsencoding: unable to load the file system codec
ModuleNotFoundError: No module named 'encodings'
Current thread 0x0000188c (most recent call first):
My path and PYTHONPATH are well configured with link to QGIS' Python folders. The problem appeared recently with use of Python 3.7.
At least for Mac recent QGIS versions seem to support only Python 3.6, not 3.7, see https://qgis.org/en/site/forusers/download.html
I downloaded openCV from http://www.lfd.uci.edu/~gohlke/pythonlibs/#opencv and installed it. When I tried to run it:
import cv2
I got error message:
RuntimeError: module compiled against API version a but this version of numpy is 9
Traceback (most recent call last):
File "<input>", line 1, in <module>
File "C:\Program Files (x86)\JetBrains\PyCharm Community Edition

module = self._system_import(name, *args, **kwargs)
ImportError: numpy.core.multiarray failed to import
I guess I need to set up virtual enviroment and install different version of Numpy, but what exact version of Numpy I need to install?
You can try using the anaconda distribution for that.
I'm using it and it works great with opencv on windows.
You can download it from here:
https://www.continuum.io/downloads
Then use conda to install opencv
conda install -c conda-forge opencv
conda comes with pre installed numpy, scipy, pandas etc and makes deployment on windows painless (since it ships with the build-chain).
You need numpy version 11 or above . You can find it in the below link.

I am a complete newbie at Python. I wanted to try to see if Pyomo (a Python package for mathematical modeling) could work under IronPython because all my code for generating the data needed for Pyomo is in C#.
I installed IronPython 2.7.5, then tried as an administrator the advice found in http://blog.ironpython.net/2014/12/pip-in-ironpython-275.html#disqus_thread on how to run "pip" for IronPython. I used the exact example they gave (installing html5lib):
ipy -X:Frames -m ensure pip
ipy -X:Frames -m pip install html5lib
The first line worked, and I see in the Lib/site-packages directory a folder called pip-6.1.1-py2.7.egg with lots of python code in it.
For the second line, I received the error:
Unhandled exception:
Traceback (most recent call last):
File "C:\Program Files (x86)\IronPython 2.7\Lib\runpy.py", line 170, in run_module
File "C:\Program Files (x86)\IronPython 2.7\Lib\runpy.py", line 111, in _get_module_details
ImportError: No module named urllib; 'pip' is a package and cannot be directly executed
At this point, I'm stuck. Any help would be appreciated.
Just in case this helps, printing out the sys.version gives:
2.7.5 (IronPython 2.7.5 (2.7.5.0) on .NET 4.0.30319.34209 (32-bit))
I encountered the same problem. It seems that IronPython can't deal with more recent versions of pip. What I did was:
remove all traces from pip and setuptools from IronPython's Lib\site-packages folder
run from a commandline: ipy.exe -X:Frames -m ensurepip
this installed an old version of pip, one that IronPython understands. Verify this by checking that a folder pip-1.5.6.dist-info appears in IronPython's Lib/site-packages
Moral of the story; don't upgrade to a newer pip version when using IronPython
