I am trying to finish a proper
Probekins
install. (Thank you, Michael Haberler, whom I hope my webstigation is properly attributing.)
My qualifications are that "I have a great project that cannot be done without it," but beyond that, I'm not a professional compiler, git-wiz, or py-hack.
I have two problems remaining--after punting and downloading alan_3301's did-it-for-you compilations from here . (Thank you, Alan!) (I didn't have much hope for these until Another Kind Reader observed that they would probably work since, necessarily, most of us have installed LinuxCNC cum EMC2 from the same Ubu ISO, and the lion's share work.)
My two remaining problems are:
1. stlvis.py's complaint about "'module' object has no attribute 'tricontourf'", related to an outdated matplotlib package in Ubuntu10.04.
2. my failure to recreate Alan's compile step with the 'comp' command necessary to execute 'sudo comp --install probekins' (which led to the punt).
Alan's probe2stl.py, stlcorr.py work for me, and generally the instructions for configuring LinuxCNC to install and use probekins from here also work. I have successfully created an STL from a set of probe points from an uneven surface, but I would like to visualize it with stlvis.py before turning it loose on the machine.
My obstacles relating to the two problems are:
2. I can't do the 'comp' because my LinuxCNC install does not have a 'comp' command (although it's mentioned here ). 'sudo which comp' returns nil.
1. I can't do an "easy_install" of a new matplotlib, because my LinuxCNC install does not report a package named 'easy_install' being available.
Re: 2, following alan_3301's Original Fine Thread here , informed me that I needed to:
$ sudo comp --install probekins
after fetching the probekins components from here . But my system has no 'comp'.
Re: 1, interestingly stlvis.py was not on the list of fetchable items from that location when I visited, but I later found it, along with another reference voronoi.py here . [Hint: click the link on the Probekins page and not in these forum posts, which may point to older versions by the time you read this?]
Looking at the stlvis.py code, as Alan did, I can see the 'pp' referenced in the error arises from matplotlib, but instructions from Probekins say to sudo apt-get easy_install.
My system:
$ uname -a
Linux santomaso 2.6.32-122-rtai #rtai SMP Tue Jul 27 12:44:07 CDT 2010 i686 GNU/Linux
says:
$ sudo apt-get install easy_install
E: Couldn't find package easy_install
That might be from a missing apt-source, but... help?
Thank you.

the comp utility is part of the package named: linuxcnc-dev
(sudo apt-get install linuxcnc-dev)
google says easy_install is in the package named: python-setuptools
(sudo apt-get install python-setuptools)

Thanks, dgarrett, I'd pretty much googled all around it.
$ sudo easy_install matplotlib
is proceeding, but taking its sweet time.
$ sudo comp --install probekins
is complaining: "Unrecognized file type for mode install: 'probekins'"
although I ran it in the same dir with probekins.c and probekins.h.

If in doubt with linux, run commandname --help or -h
There is no file called probekins, so comp cannot compile and install it.
You want to compile the .c file, so the command is sudo comp --install probekins.c
I have just compiled it and it builds fine

Thanks, ArcEye.
I am very sorry all; I have no explanation for misreading the instruction:
$ sudo comp --install probekins.c
I did type it in, over and over, expecting a different result, if that helps. (Didn't think so.)
Typing it, as-directed, resulted in SUCCESS! (To later readers, comp reported a couple of "warnings" about "mixed declarations and code" and about an undefined "__divdi3", but the desired module is in fact created anyway. NOTE: don't look for it in the same directory with probekins.c; on success it's put into /usr/realtime-2.6.32-122-rtai/modules/linuxcnc/.)
One DOWN. One to go.
I fear now to report that stlvis.py does not yet work, although the easy_install worked and finished with no errors. Before performing that step, I ran:
$ sudo dpkg --get-selections | grep matplotlib # to identify installed matplotlib packages
$ sudo apt-get remove <packages_found>
The easy_install seemed to "choose" a version of matplotlib (1.3.1, and as the error has changed, I wonder if it chose the one necessary for stlvis.py. However, before I could investigate that, it had me wreck my 'easy_install' installation...
I did as directed:
$ sudo easy_install -U distribute
and now
$ sudo easy_install matplotlib
dumps:
In fact, so does a simple:
$ sudo easy_install
I'll apt-get remove/install the python-setuptools package to see if I can get past this. (I did not recall seeing a reference to "-U distribute" in earlier tries, but as the world now knows, I don't always read carefully...)

No luck on re-apt-getting python-setuptools: easy_install still seems broken by "distribute" whatever that is.
Hoping to "back out" of the "distribute" install without using "easy_install" (but not knowing how to go about it for removal anyway), I scrolled back up to where it had been installed:
$ sudo easy_install -U distribute
appears to have replaced a previous version (<0.6.28) with 0.7.3 (and broken easy_install itself)
which I'd like to back out of (and must use something besides easy_install to do), but
$ sudo dpkg --get-selections | grep "distri"
returns nil.
Thank you.

Hi
I don't know anything about easy_install, but I cannot see where you are getting your instructions from.
The steps in the wiki are
This is to remove the old copy of python-matplotlib, install something which will fetch more recent python libraries and then install a more recent version of python-matplotlib
Nothing about easy_install -U distribute
Distribute itself appaears to be a fork of the setuptools project, so appears to be a replacement for easy_install not an adjunct to it
I can only suggest that you remove what you added and start again.
The trouble with using 2 different package managers on one system is that apt is unaware of what easy_install has done and vice versa, so you need to remove each package with the manager that installed it,
until you are back at your start point again.
It is quite easy to screw up everything, when dependencies were required for one package but are also required by another one the manager is unaware of, or conflict with an existing package.
Good Luck

ArcEye,
Thank you for sane advice.
Sparing you a dreary read:
I'd like to try the matplotlib version previous to 1.3.1 and install it manuallly if possible.
It was easy_install itself which instructed the step:
$ sudo easy_install -U distribute
having refused to do
$ sudo easy_install matplotlib
without it.
I've now done:
$ sudo apt-get remove python-setuptools # no more easy_install
$ sudo apt-get remove matplotlib # reports not present anyway
$ which easy_install
/usr/local/bin/easy_install # huh?!
Turns out there are still two (easy_install[-2.6]) "easy_installs" in /usr/local/bin/, both scripts, and both failing with errors about missing entrypoints. Dff'ing them brings up info about my little friend 'distribute'. (Turns out distribute's not evil; it's in easy_install from the get-go, but somehow the version freaked.)
$ sudo rm /usr/local/bin/easy_install* # I don't think I should have to do this, but w/o it, but they are not overwritten by apt-get install...
Weirder and weirder however.
$ sudo apt-get install python-setuptools # as before, but
$ which easy_install
/usr/bin/easy_install # what? What?!
$ diff /usr/bin/easy_install* # still shows 'distribute' is a key component
But THIS easy_install works.
$ easy_install
and provides this reference, for any future reader who has not succumbed on this quest:
peak.telecommunity.com/EasyInstall.html
as well as the information that the default directory for installs is:
/usr/local/lib/python2.6/dist-packages/
Now ready for The Acid Test:
$ sudo easy_install matplotlib # same as before, sifts through a number of sites and picks "Best match: matplotlib 1.3.1"
$ ~/linuxcnc/kinematics/stlvis.py
$ ./stlvis.py
Disappointment: "No module named matplotlib.pyplot."
However, I still have the list of sites easy_install contacted before picking v1.3.1 in the console:
I visited the first one (and the one which offered 1.3.1) and found a list of all the versions.
I'd like to try the version previous to 1.3.1 and install it mamnuallly if possible.

You don't need to, as this page clearly shows, pyplot is in 1.3.1 and an integral part of it.

I would suspect that your paths are not right and the lib is not being found.

Thank you for that. I was dreading it even as I contemplated it.
I read it as having to do with Python configuration which I'll look into.
