datamind in brainvisa 4.3

[guillaume]

Hello,

I see that the datamind toolbox is "available" by default in the stable version of brainvisa4.3...
...but have the following error when trying to launch it:

Traceback (most recent call last): File "/home/me/BVs/brainvisa-4.3.0/bin/real-bin/datamind", line 70, in <module> import datamind.gui.MainGui File "/home/me/BVs/brainvisa-4.3.0/python/datamind/gui/MainGui.py", line 46, in <module> from qt3gui.MainGui import * File "/home/me/BVs/brainvisa-4.3.0/python/datamind/gui/MainGui.py", line 34, in <module> ImportError: libqassistantclient.so.1: cannot open shared object file: No such file or directory

So I suspect a missing lib such as pyqt-dev or similar.
I just wonder if it is plausible to make datamind running with acceptable effort or is it still quite complicated?

cheers,
gui

Hi Guillaume,
In your case datamind is trying to load Qt3/PyQt3, which it should not, it should use Qt4/PyQt4, so something is going wrong.
Try to edit the source <brainvisa>/python/datamind/gui/MainGui.py and print if USE_QT4 is correctly set to True, and if the modules importation is OK.

Hi Denis,

in fact the problem seems to be the import of datamind.config.
In the IPyhton shell I can import datamind but not datamind.config, does it make sense for you?

Hi Guillaume,
That's right, the config.py file seems to me missing in the package, I have to investigate why.
You can recreate it, it should be in

Code: Select all

<brainvisa>/python/datamind/config.py

and contains a single line:

Code: Select all

MAJOR_QT_VERSION = 4

Good Denis,

then I had to modify <brainvisa>/python/datamind/gui/MainGui.py like following:
from datamind.config import MAJOR_QT_VERSIONi ==> from datamind.config import MAJOR_QT_VERSION
i.e. just suppress the 'i' and now I have an error that corresponds to a library for R which is missing, but this is related to my install of R.

I will continue the fight on monday...

Strange, I don't know where that "i" comes from...

For datamind, R needs a bunch of modules. Edouard used to have a list somewhere, but I don't know if it is up to date.
Try looking in ftp://ftp.cea.fr/pub/dsv/anatomist/unreleased/
There is a file "datamind_for_bv.tgz" there, which may contain it.

Denis, in fact I think the "i" was a mistake I personally made, it is not there in another install of bv4.3.0 I have on my laptop, sorry for that.

Thank you for the link to the modules for R, I already have it from an old post on the forum and I'm currently trying to install them all.
I've never been so close to use datamind, I'll tell you if it works.

Hi Denis,
I've never been so close...
... but it still doesnt work.
Now I'm facing issues in the install of R packages so maybe shoul I contact Edouard...

I've installed the precompiled version of R from the ftp, such that the gui of datamind appears properly however, at the start of datamind I have the following error:

Code: Select all

Error in dyn.load(file, DLLpath = DLLpath, ...) : unable to load shared library '/home/guillaume/BVs/datamind_for_bv/tmp_install_R/r/lib/R/library/e1071/libs/e1071.so': libstdc++.so.6: wrong ELF class: ELFCLASS64 
Error : package/namespace load failed for 'e1071' 

while a "locate" shows me several libstdc++.so.6, including the one in brainvisa... so it may just be a path to set properly...

But after that when I try to plot a variable to test (plot1D in plot) I get the following exception:

Code: Select all

I would just add a BIG WARNING when trying to install the pre-compiled R from the FTP:
There is a cute "rm -rf ${SRC_R}" in the r/setup.sh that is likely to produce some trouble when trying to install it in /usr/local as suggested in the readme.txt... as I did...
I suggest to comment it!

Hi Guillaume,
Hm, yes you'd probably rather contact Edouard. The precompiled R and script on the ftp site are probably largely outdated. Actually I don't think datamind is really maintained currently.
