Installation on Ubuntu with Canopy

[rvalenzuelar]

I followed the installation instructions:

$ python setup.py build
$ sudo python setup.py install

...but then I get:

Traceback (most recent call last):
  File "setup.py", line 180, in <module>
    setup_package()
  File "setup.py", line 162, in setup_package
    from numpy.distutils.core import setup
ImportError: No module named numpy.distutils.core

I'm using Ubuntu 14.04 LTS.

Could you please type: which python

And send the output

Thanks.

@rvalenzuelar Do you have the Canopy version of NumPy installed? Py-ART needs this package for installation and at run-time. You can check if NumPy is available and what version is installed by executing the following in a terminal window.

python -c "import numpy; print(numpy.__version__)"

[rvalenzuelar]

After typing that command I get:

1.8.1

[jjhelmus]

How about

python -c "from numpy.distutils.core import setup"

Does that give the same ImportError or does it succeed?

Also is this Python 2 or 3, python --version should give you the full version.

[rvalenzuelar]

The output of the command is similar:

Traceback (most recent call last):
File "string", line 1, in <module>
ImportError: No module named disutils.core

And the version is:

Python 2.7.6 -- 32 bit

[jjhelmus]

Make sure you have a t in distutils, from the error it looks like it was left out. I don't typically run on 32-bit Python, let me create a VM and try to reproduce the error.

[rvalenzuelar]

Sorry, you are right. I run the same command with the t and I get no error message.

[jjhelmus]

Wait, does the error message get printed after the sudo python setup.py install command? If so the issue is that the superuser has a different Python environment. Try removing the sudo, which should work if you have write access to the site-packages directory somewhere in /home/raul/Enthought/Canopy_32bit/User. If that does not work python setup.py install --user to do a user install into /home/raul/.local/ .

Ok, I tried:

$ python setup.py install

and I got:

I have nose installed in Canopy, so I run the nosetests from outside the source directory :

~/Github$ nosetests --exe pyart/

and I get:

The tests cannot be run from the source directory (there is an outstanding bug report to fix this). If you change to a new directory (cd ~ will work), you should be able to run the tests with the same command.

Ok, I tried:

~$ nosetests --exe pyart

and I get:

I have wxPython 2.8.10.1-7 installed :/

[jjhelmus]

Do you have an X server running on this machine and if logging in remotely do you have X forwarded (ssh -XY)? If neither of those are true try using a non-interactive backend for matplotlib for the time being. This is controlled by the ~/.matplotlib/matplotlibrc file on the line:

# the default backend; one of GTK GTKAgg GTKCairo GTK3Agg GTK3Cairo
# CocoaAgg MacOSX Qt4Agg TkAgg WX WXAgg Agg Cairo GDK PS PDF SVG
# Template
# You can also deploy your own backend outside of matplotlib by
# referring to the module name (which must be in the PYTHONPATH) as
# 'module://my_backend'
backend      : Agg

Changing the backend to Agg should allow the tests to complete. For interactive work you will want to set this to an interactive backend. There any many choice, usually trying a few and seeing which ones work is best.

[rvalenzuelar]

Thanks @jjhelmus , now it passed the test.

Just for reference, I found the matplotlibrc in:

~/Enthought/Canopy_32bit/User/lib/python2.7/site-packages/matplotlib/mpl-data/matplotlibrc
