ImportError: No module named radiomics

[devareddy]

While am trying to run example under bin directory from Jupyter & command prompt am experiencing
"ImportError: No module named radiomics".
Any help in fixing this is appreciated.

Thanks in advance

@devareddy, did you install the package using python setup.py install?
Additionally, if you have 2 versions of python installed, you need to be careful on which version python is installed and which python version jupyter is running.

Thanks JoostJM.
Yes i did install using python setup.py install.
Last two lines after running above command:
"Using /usr/local/lib/python2.7/dist-packages"
"Finished processing dependencies for pyradiomics==1.1.0.post5.dev0+g79a84e9"
Am running Jupyter using Python 2.
Am i missing some thing?

@devareddy, Did you start jupyter/cmd before you installed the package? If that is the case, you'll need to restart cmd/jupyter (for jupyter, also restart the cmd window), as the install updates the python easy-install path (which python uses to find the package).

If you want to manually check if pyradiomics is installed, go to your python directory, and go to the Lib/site-packages folders. There should be a pyradiomics folder in there, containing the radiomics folder and a data folder.

@JoostJM, Thanks for the help.Am able run the example for command line but not from jupyter .
But it is giving an error while running > python helloRadiomics.py
Error loading C extensions, switching to python calculation:
Traceback (most recent call last):
File "/home/user/radiomics/pyradiomics/radiomics/init.py", line 140, in
from radiomics import _cmatrices as cMatrices
ImportError: cannot import name _cmatrices
Can you help in fixing this issue?
Thanks in advance.

@devareddy This means that PyRadiomics is loading, but has trouble finding the C compiled extensions.
It is a bug we come across more often, and is caused by the fact that as jupyter is running from within the bin folder with python 2.7, it finds the source code radiomics folder, and not the installed folder. For the python files, this makes no difference. However, the C extensions are only present in the installed folder when you run python setup.py install.

You can fix this bug by running python setup.py develop, which generates an in-source build (i.e. compiles the C extensions and copies them to the radiomics folder in the git repo.
