wx.lib.pubsub import Publisher

[marc]

Hi all;

I can see this has been discussed before in previous emails, but after
reading them, I still cannot resolve this issue.
I am trying to use pyinstaller to build a Windows executable - where
code makes use of :

wx.lib.pubsub import Publisher

... allowing the model to notify the controller that a change has
occurred.

However, when the executable is run, I get a "ImportError: cannot
import name Publisher" error.
I've tried using all the different imports mentioned on various
threads, most work from Python, but fail to import once run from a
Windows executable built with pyinstaller

Could someone please let me know - currently, what's the best work
around for this issue? I'd really like to get this resolved.

Many thanks for your help,
Marc

While I'm not proud of this (it's a complete hack), the following seems to work for me.  This is with the pubsub included with wxpython 2.8.11 and later, and you must import in your application like this:

    from wx.lib.pubsub import setuparg1

    from wx.lib.pubsub import pub as Publisher

I can only verify that this works with the arg1 protocol; it probably will with kwargs as well, but I have not verified.

Anyway, here are the two hooks:

hook-wx.lib.pubsub.core.py:

------------------------- cut here  ----

import os

import sys

def hook(mod):

   pth = str(mod.__path__[0])

   if os.path.isdir(pth):

      # if the user imported setuparg1, this is detected by the hook-wx.lib.pubsub.setuparg1.py hook.  That

      # hook sets sys.wxpubsub to "arg1", and we set the appropriate path here.

      protocol = getattr(sys,'wxpubsub','kwargs')

      print "wx.lib.pubsub: Adding %s protocol path"%protocol

      mod.__path__.append(os.path.normpath(os.path.join(pth, protocol)))

     

   return mod

------------------------- cut here  ----

And this for hook-wx.lib.pubsub.setuparg1.py:

------------------------- cut here  ----

import os

import sys

# if the user imports setuparg1, we just set an attribute in sys that allows us to later find out

# about this.

sys.wxpubsub = "arg1"

------------------------- cut here  ---- 

I told you it was a hack! :O  Maybe the pyinstaller folks who know what they are doing can look at this and determine the correct solution.

I'm using:
XP Pro SP3
Python V 2.7.3

wx.version returns '2.8.12.1 (msw-ansi)'

I have tried both stable pyinstaller and development one from yesterday (possible version: 2145d84)

When I switched from importing Publisher to 

I've even tried including this hook below:

import os

def hook(mod):

    pth = str(mod.__path__[0])

    if os.path.isdir(pth):

        mod.__path__.append(os.path.normpath(os.path.join(pth, 'kwargs')))

After changing the publisher import:

from wx.lib.pubsub import setupkwargs

from wx.lib.pubsub import setuparg1

from wx.lib.pubsub import pub as Publisher
(I have tried every combination of the first two, with both, without  one or the other, and with only import Publisher..)

With one or the other I seem to get:

I very much appreciate the very quick reply, I tried using what you have and it still didn't work and gave me the same error. I'm assuming I've done something wrong.

My 'startme.spec' file is below

-----------------------------------------

# -*- mode: python -*-

a = Analysis(['C:\\Documents and Settings\\Tom\\Desktop\\ToPy v0.001\\startme.py', 

'C:\\Documents and Settings\\Tom\\Desktop\\ToPy v0.001\\irep.py', 'C:\\Documents and 

Settings\\Tom\\Desktop\\ToPy v0.001\\webpro.py'],

             pathex=['C:\\DOCUME~1\\Tom\\Desktop\\PYINST~1'],

             hiddenimports=['wx.lib.pubsub.core', 'wx.lib.pubsub.setuparg1'],

             hookspath='C:\\Documents and 

Settings\\Tom\\Desktop\\pyinstaller-pyinstaller-2145d84\\newhooks\\')

pyz = PYZ(a.pure)

exe = EXE(pyz,

          a.scripts,

          a.binaries,

          a.zipfiles,

          a.datas,

          name=os.path.join('dist', 'startme.exe'),

          debug=False,

          strip=None,

          upx=True,

          console=True )

-------------------------------------------------

and the command im running (as startme.spec is in the same folder) is simply

----------------------------

python pyinstaller.py startme.spec

-----------------------------

Am I missing something? I've got that sneaky something simple is missing feeling. I keep trying the same few things over and over again and all its doing is  making me realize first hand the definition of insanity. I don't really know or understand wx or pyinstaller enough to know where to even really start. I'm still just learning python. 

Thanks again for your help.

[Daniel Hyams]

This is probably the blind leading the blind here.

To me, your Analysis call is a little strange.  Mine looks like this:

   a = Analysis([catpath(HOMEPATH,'support','_mountzlib.py'), 

              catpath(HOMEPATH,'support','useUnicode.py'),

              catpath('..','..',srcdir,'src','main.py')],

              pathex=[srcpath])

where "catpath" is just a little function that I wrote to concatenate multiple strings into one path.  Note that I only have one of my own py files in there, and that's it.  No hiddenimports, and no hookspath; I put my custom hooks just alongside pyinstallers; I'm not sure if that makes a difference or not.

Also, are you seeing a print statement during the build that says "wx.lib.pubsub: adding arg1 protocol path"?  If not, then the hooks that I gave you are not getting called.

Also, are you trying to use the arg1 protocol or the kwargs protocol in your application?

Right after analizing my files I get:

9296 INFO: Hidden import 'wx.lib.pubsub.core' has been found otherwise

9296 INFO: Hidden import 'wx.lib.pubsub.setuparg1' has been found otherwise

9296 INFO: Hidden import 'encodings' has been found otherwise

9296 INFO: Looking for run-time hooks

So I think they are being loaded without requiring it. I tried to edit my file and hosed it so I reran the pyinstaller from the command line with no options. On the bright side I got a different error, I think I'm slowly making progress. :) Now it says I'm missing mechanize. However that is in include from the second file.

This was after moving your files to the hooks directory, I think that did the trick as far as this little hickup goes. Now I need to resolve that one, Hopefully I'll have some time later on. 

Thanks so much for your help! If you are the blind leader, you have at least traveled the road enough times to remember the path :)

Look at this ticket.

http://www.pyinstaller.org/ticket/312

We have travelled that path as well but rewrote our code to get rid of pubsub.

Once wxpython 3.0 will be released we might look at it again.

What are you using instead of wx, if I may ask.

Could anyone please summarize how should be the proper fix in
PyInstaller?

[Daniel Hyams]

I think that the fix that I have a couple of posts up (a modification to wx.lib.pubsub.core hook, and the addition of a "setuparg1" hook) works.  However, it is a horrible kludge, because it sets a variable in the sys module...in effect setting a global flag if the importing of setuparg1 is done at any point.  I thought that there might be a better way in pyinstaller of recording that the setuparg1 module had been imported.

basically the procedure is:

  1) watch for the import wx.lib.pubsub.setuparg1, setting a flag if it is.

  2) when wx.lib.pubsub.core is later imported, add the appropriate path (either arg1 or kwargs) depending on the flag above.

If I get some time (hard to come by right now), I will add test cases to pyinstaller and test this out on toy cases.  I know that my application is working just fine using wxpython's pubsub, but my fear is that I've forgotten some other tweak that I made, because it has been a while since I did it.

Sorry I'm at work now and its taken me awhile to get some spare time. I literally just added his files from above with my other hook files and then ran from command:

python pyinstaller.py "path/to/files/1" "path/to/files/2" "path/to/files/3"

So I'm thinking for this the fix is Daniels hook files. =)

Now I am still having issues with other parts that I don't have the time to tend to currently, but when I do I'll let you know if its working as a whole or not.

[Daniel Hyams]

I've just verified that those two hooks above work, at least with the arg1 variation of pubsub.  I'll test with the kwarg variation, and then put up a pull request.

We are still using wx but we got rid of pubsub for the moment.

[Tom Tijerina]

Sorry it took me awhile for an update Daniel.

I just downloaded a new copy, and I believe I fixed the mechanize issue, now I'm running back into publisher issues.

To eliminate a few of the other libraries I used I did a quick google on a simple wx pubsub demonstration. I came up with this site: http://www.blog.pythonlibrary.org/2010/06/27/wxpython-and-pubsub-a-simple-tutorial/  I have tested his code, it behaves exactly the same way as mine. If you have wx installed and figure something out please let me know. :)

Below is a table of import to errors encountered trying to run the onefile exe from both the test and from my script. I hope somehow it can help.

Tom:

I'm afraid that the download from github might not be working like I thought it does; you might just be redownloading the "develop" branch from github, which does not have the wx.lib.pubsub fixes merged in yet.  To verify, see if a hook with "setuparg1" in the name exists in PyInstaller/hooks.

[Tom Tijerina]

Daniel, 

I just got it from the github, I didn't find that file from what I got in git, or in what I had downloaded from development zip. I'm not sure if I'm looking in the correct place. The only file with that name that I can find is in C:\Python27\Lib\site-packages\wx-2.8-msw-ansi\wx\lib\pubsub however I did check and I found this in the log:

12312 INFO: Hidden import 'wx.lib.pubsub.core' has been found otherwise

12312 INFO: Analyzing hidden import 'wx.lib.pubsub.setuparg1'

12359 INFO: Hidden import 'encodings' has been found otherwise

Wouldn't that mean that it did find it, versus complaining that it couldn't find it?

-Tom

[Daniel Hyams]

I'm guessing that you didn't get the correction version (not your fault, but just the way it goes).  I'm pretty confident that it is working, since I can put together a test case that demonstrates a before/after.  So don't worry about it....perhaps wait until the merge of my pull request, and then try.

[Tom Tijerina]

Just let me know when. :)

Thanks

[Tom Tijerina]

I went and manually put the hook files back in. I'm still having issues with the wx library, I'm not sure if this is related or not.
