Can't Get NetworkX to run in Spyder

[Chris]

Hi,

I am trying to run NetworkX in Spyder but am unable to get the module networkx recognised.

I downloaded NetworkX from  http://pypi.python.org/pypi/networkx and installed NetworkX via pip using "pip install networkx". It appeared to complete OK. When I repeat the command I get

Last login: Wed Mar 18 20:07:35 on ttys000

Fl1cker:~ cbhe$ pip install networkx

Requirement already satisfied (use --upgrade to upgrade): networkx in /Library/Python/2.7/site-packages/networkx-1.9.1-py2.7.egg

Requirement already satisfied (use --upgrade to upgrade): decorator>=3.4.0 in /Library/Python/2.7/site-packages/decorator-3.4.0-py2.7.egg (from networkx)

Fl1cker:~ cbhe$ 

which suggests to me that it is installed.

However when I try to import network in Spyder using "import networkx as nx" I get

runfile('Z:/Users/cbhe/scripts/netw0.py', wdir='Z:/Users/cbhe/scripts')

Traceback (most recent call last):

  File "<ipython-input-2-5455c9a69031>", line 1, in <module>

    runfile('Z:/Users/cbhe/scripts/netw0.py', wdir='Z:/Users/cbhe/scripts')

  File "C:\Python27\lib\site-packages\spyderlib\widgets\externalshell\sitecustomize.py", line 601, in runfile

    execfile(filename, namespace)

  File "C:\Python27\lib\site-packages\spyderlib\widgets\externalshell\sitecustomize.py", line 66, in execfile

    exec(compile(scripttext, filename, 'exec'), glob, loc)

  File "Z:/Users/cbhe/scripts/netw0.py", line 1, in <module>

    import networkx as nx

ImportError: No module named networkx

I can only think that it is a Python Path issue, but I have tried numerous paths that all produce the same result.

Any suggestions would be really welcome as I am being held up by this problem.

Some information is needed I think.

1) Your pip install lines look they where done on a Unix* machine, but
the traceback looks like it comes from a Windows machine.
Could you explain your layout some?

2) What version of Spyder and how was it installed?

3) Can you open a Python interpreter and import networkx?

Adrian,

Thanks for the quick reply.

I am running OS X 10.10.2 and have a Parallels 10.1.4 Windows 7 virtual machine. I can run Spyder 2.3.2 in both OS X and Windows 7.

Both the Windows and OS X Spyder were installed from downloaded installers. I can execute Python code on both instances.

NetworkX was installed via the OS X command line using pip and I have tried to access it in both the OS X and Windows Spyder, but get the same message.

I opened a python interpreter via the command line command. The attached screenshot shows the result; which I interpret to show that networkx was imported.

I hope this helps in understanding my problem.

Chris

Yes, I think. For now and to keep the moving parts to a minimum lets
stay in one OS. Since the chances that a Windows VM can see libraries
installed on OS X would seem to be slim to none, lets stick with OS X.

FYI another way to see if pip has installed something is to do:

pip freeze

which can return a lot of information. So in this case on OS X:

pip freeze | grep -i networkx

The screenshot shows that networkx has been installed in OS X.

What happens if you run Spyder in OS X and in either the Python or
IPython console do?:

import networkx as nx

Adrian,

Sorry about the delay, I’ve been on the road (again).

So I did the pip freeze and it returned

Last login: Fri Mar 20 20:31:24 on ttys000

Fl1cker:~ cbhe$ pip freeze | grep -i networkx

networkx==1.9.1

Fl1cker:~ cbhe$ exit

logout

[Process completed]

The result when I open Spyder in OS X and  run “import networkx as nx” in the IPython and Python consoles is shown in the two attached screenshots.

To me this suggests a path issue but ????

But you are not doing import networkx as nx, you are doing
runfile(some_script).

In the consoles at the prompt type import networkx as nx and see if that
works?

Also could you just cut and paste the commands and the tracebacks into
the email instead of using screenshots. It just makes it easier to
follow, less context shifts. Thanks.

Hmmm.

I know you said you installed Spyder using an installer previously, so
which one was that exactly?

Do you have more than one Python version installed on OS X?

[Chris Edwards]

Adrian,

Further to your question about more than one version of Python see the extract from my /usr/bin below:

I am not a OS X user so I getting into deep water here, but to me it
looks like there are three versions of Python installed. I say this
because of lines like this:

I do not see anything pointing at them or they pointing at anything
else, which would seem to indicate to me they are a separate instance of
Python. This would need confirmation from someone that actually
understands OS X. I would hesitate deleting everything as I pretty sure
the system probably needs Python for something. I could see uninstalling
the Spyder dmgs and then seeing what you have.

The screenshots did not come through. In any event for the VMs you will
need networkx installed in each for Spyder to pick it up.

I did a Google search on this and came away more confused then
enlightened. If it where me I would look for site-packages directories.
As to finding out what is running on the command line do:

python --version

and for the symlinks above:

python2.6 --version
python2.7 --version

There was no change in behaviour and I still can’t import NetworkX from within Spyder. I have actually successfully executed a program using NetworkX from the command line!

I think what I need to do is somehow make Spyder recognise Python 2.7.9 but feel I am in some sort of infinite loop here!

I gather from searching the web that I am not the first to have run into problems with multiple versions of Python and wonder if his has been addressed somewhere that I haven’t discovered.

Anyway thanks for the help so far.

Here you should do:

>>> help(networkx)

to see where it is actually installed

So something like:
>>> import psycopg2
>>> help(psycopg2)

Help on package psycopg2:

NAME
psycopg2 - A Python driver for PostgreSQL

FILE
/usr/lib/python2.7/site-packages/psycopg2/__init__.py
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

While you are in the Python interpreter I would also do:

>>> import sys
>>> sys.path

This will show you the PYTHONPATH the system interpreter is seeing.

This will show you the PYTHONPATH the system interpreter is seeing.

Repeat this in your Spyder Python/IPython consoles to determine what
PYTHONPATH they are seeing.

From the above it seems clear that the two paths are different. Now, how does one (hopefully easily) correct the Spyder system path??

There are questions to be answered before we get that point:

1) Where is:

/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/spyder-1.1.3-py2.7.egg'

coming from?

2) In the Spyder console path is:

'/Library/Python/2.7/site-packages/networkx-1.9.1-py2.7.egg',

So are you sure you cannot import it into the Spyder Python console?

3) What is in ?:

'/Applications/Spyder-Py2.app/Contents/Resources/lib/python2.7/site-packages'

4) Again, how exactly are you installing the system Python?

So it appears that I can’t run IPython from the OS X command line and (as before) networkx can be imported by the system Python.

Access to Networkx

Networkx is referenced in the path obtained from running

The only site-packages file is a .zip file that I assume came along with a download.

Installation of Python 2.7.9

I installed Python (hopefully correctly) by using the Launcher (icon looks like a V2 rocket) that accompanied the download.I don’t understand the relationship between the /Library and the /Applications file references but they appear to me to be the main difference between the system Python path and the Spyder Python path

I suspect these answers may not really address what you want to know but hope they help in some way.

That is not what you showed in your previous post. Go back to it and
take a look and confirm whether the paths you show are correct.

Where did you get the Python package to begin with?

I am thinking the only way to solve this is to go to square one and
start over from scratch. The only caveat is how deeply your system
depends on Python.

Source of Python package

I downloaded the Python package from

https://www.python.org/downloads/source/

Starting again from scratch

If you recommend that I do this would you be able to outline the steps required.

Summary

What I find odd is the fact that I can execute a python program that imports Networkx from the OS X Terminal, but that package is not recognised by Spyder. I can’t help wondering if the problem could be solved by adding to the Spyder system path (if that is possible).

Thanks for your patience.

Now that IPython seems to work and the paths are clearer I would hold off.

It is possible. In Spyder go to Tools-->PYTHONPATH manager and add the
system path for packages. From the looks of it, that is:

/Library/Python/2.7/site-packages/

if that does not work, you could get specific:

/Library/Python/2.7/site-packages/networkx-1.9.1-py2.7.egg
