I was trying to install Dioptas using python setup_win_32.py install.
During the installation I got the following error:
no module named scipy.linalg.dsolve.umfpack
Does anyone know how I can resolve this issue?
I am running on Windows 7 (32-bit) and have installed all the following required libraries:
python 2.7
PyQt4
numpy
scipy
pyFAI
fabio
pyqtgraph
scikit-image
pyopencl
fftw3
UMFPACK wrapper has been removed from scipy starting from version 0.14.
A replacement is available as a scikit.

Working on python 2.7(not anaconda). Operating system Windows server 2012 R2
The pypi installation mentions two fixes for this, installing Visual C++ redistributable 2015 and Universal C Runtime.
As well as a manual fix for older anaconda versions, which is for python3(I am not using anaconda version, and also my python version is 2.7 so presuming it doesn't apply in my case)
link here:
https://pypi.org/project/opencv-python/
installed both the dependencies but couldn't get it to work.
Any ideas on how I may fix this?
Since Python 2.7 is still supported, this could be the possible solution.
Installing OpenCV from prebuilt binaries:
Below Python packages are to be downloaded and installed to their default locations.
Python-2.7.x
Numpy
Matplotlib
Install all packages into their default locations. Python will be installed to C:/Python27/.
After installation, open Python IDLE. Enter import numpy and make sure Numpy is working fine.
Download latest OpenCV release and install it : Latest OpenCV-build
Goto opencv/build/python/2.7 folder.
Copy cv2.pyd to C:/Python27/lib/site-packeges.
Open Python IDLE and type following codes in Python terminal.
import cv2
print cv2.__version__
I'm trying to install open cv for a while , according TO INSTRUCTIONS the numpy library should be automatically installed with 2.7.13 but when i try to import it it gives the following error:
Numpy.core.multiarray Failed to import
It also came across the same problem. I installed "numpy" manually in C:\Python27\Lib\site-packages. You can find the latest versions of numpy here. You can download the executable file directly. Just install it at the location I previously mentioned. Hope this is helpful.
Can anyone tell me how can i setup a python working environment with numpy and scipy?
I have succesfully downloaded python but i can't install numpy,it gives me an error "unable to find vcvarsall.bat"
You can install Enthought Canopy, which is an easy way to get python with lots of useful packages (including numpy and scipy) built in.
Similar to jh314's answer, there is also Anaconda.
Download the executable installers from Christoph Gohlke's Python Extension Packages for Windows repository. Numpy is here and Scipy is here.
I'm trying to get Numpy working in Python 2.7.8, on a Ubuntu 12.0.4 operating system. I installed Python 2.7.8 as my default python, then installed the SciPy stack according to the site instructions. I double-checked that numpy installed in the /usr/lib/Python2.7 directory. When I run python the version is 2.7.8, but of course it can't find Numpy. Is there any way to fix this? Or should I just throw this computer out the window?
Edit: Apparently I have both 2.7.8 and 2.7.3 installed, both to Python2.7 directory. I have no idea how to get rid of either one...
I have used Scipy for some time. This is the first time I am using it for Signal processing!
But when I import modules like
from scipy import signal
from scipy import special
I get the error:
ImportError: DLL load failed: The specified module could not be found.
I am using Python 2.7.3 with Scipy 0.12.0 on 32-Bit Windows.
What should I do ?
This problem can be solved if instead of installing the usual numpy distribution, the numpy-MKL package is installed.
This package is available here.
Do remove the previous installation before going with the new one!
I already had numpy+mkl installed, but still I faced similar error.
Reinstalling has solved the issue:
pip uninstall numpy-1.13.1+mkl-cp35-cp35m-win_amd64.whl
pip install numpy-1.13.1+mkl-cp35-cp35m-win_amd64.whl
I installed numpy-MKL from here for Python 3.5.1, but it didn't solve the problem until I added the folder C:\Program Files\Python35\Lib\site-packages\numpy\core to system path.
Similar to the OP, I already had the Intel MKL libraries installed on my system. I was unable to load scipy.linalg with the same error message. I uninstalled the old version of numpy and scipy (which I installed before installing the Intel compilers and math libraries). Then ran pip install scipy, and magically I could now import scipy.linalg without the error.
I'm not entirely sure what caused it, and why it was unable to find the library it needed. But it somehow fixed the problem for me on Python 3.7.1 with Anaconda.
I had an issue importing sklearn because of my Scipy installation.
I fixed this by going to here and downloading the right version of numpy for my computer. Then I did the same for Scipy by going here and downloading the MKL version for my computer.
Once I did that, everything worked!
To check the supported tags for wheel version for your system you can run the following command in the command prompt: pip debug --verbose.
You can install the .whl files for numpy and scipy by doing: pip install {filename}.whl
I had this issue on 3.6 and reinstalling didn't work,downloading the wheel didn't work. I found a solution that did work:
go to "site-packages/scipy" folder and open __init__.py file for editting.
At the very bottom add this line of code:
from . import signal
from . import special
from . import linalg
from . import <insert missing submodule here>
this is the only solution that has worked for me and it should work for any one
