'NoneType' object attribute '__doc__' is read-only

Hi Everyone,

Installed triqs on a yet another cluster machine. ( MacOS, Darwin kernel 10.8.0 ) Running a following scipt:

from pytriqs.Base.GF_Local import *
from pytriqs.Base.Archive import *
import pytriqs.Base.Utility.MPI as MPI

Getting a following error now:

Traceback (most recent call last):
  File "MPITest.py", line 3, in 
    import pytriqs.Base.Utility.MPI as MPI
  File "/Volumes/Users/antipov/_local/lib/python2.6/site-packages/pytriqs/Base/Utility/MPI.py", line 30, in 
    from pytriqs.boost.mpi import *
  File "/Volumes/Users/antipov/_local/lib/python2.6/site-packages/pytriqs/boost/__init__.py", line 9, in 
    import mpi
AttributeError: 'NoneType' object attribute '__doc__' is read-only

The error dissapears if I just leave import pytriqs.Base.Utility.MPI as MPI line. Thus I receive the same error for any tutorial scripts, e.g. aim.py from http://ipht.cea.fr/triqs/doc/user_manual/solvers/aim.html#aim Any good ideas on that?

Hey Andrey! Can you tell me which version of python and of boost you are using? Thanks!

[aeantipov]

Hi, Michel! That is boost 1.49 and python 2.6.7 (built by apple-gcc). I compiled with intel 12.0.4. Also hdf is 1.8.8. Compiled triqs-0.8 - this problem doesn't emerge there.

[aeantipov]

Some update. The error is produced with the intel compiler

CXX="icpc" CC="icc" FC="ifort"
cmake \
-DBOOST_SOURCE_DIR=/Volumes/Users/antipov/dist/boost_1_49_0 \
-DCMAKE_INSTALL_PREFIX=/Volumes/Users/antipov/_local \
-DPYTHON_INTERPRETER="/opt/local/bin/python" \
-DBuild_Wien2k=false \
-DBuild_HubbardI=false \
${path_to_triqs}

As soon as I switch to the configuration

CXX="g++" CC="gcc" FC="/opt/local/bin/gfortran-mp-4.4" 
cmake \
-DBOOST_SOURCE_DIR=/Volumes/Users/antipov/dist/boost_1_49_0 \
-DCMAKE_INSTALL_PREFIX=/Volumes/Users/antipov/_local \
-DPYTHON_INTERPRETER="/opt/local/bin/python" \
-DBuild_Wien2k=false \
-DBuild_HubbardI=false \
-DCMAKE_COMPILER_IS_GNUCXX=1 \
${path_to_triqs}

the metioned scripts start to work.

[mferrero]

Let me understand this right. When you compile the tagged version 0.8 there is no problem?

[aeantipov]

Just made some updates to the last post - there's nothing with mkl. Yes - with the triqs downloaded from https://github.com/TRIQS/TRIQS/tarball/v0.8 I don't receive this particular problem.

[mferrero]

OK, then can you try to see if the problem appeared after the commit 3d266d7cdfd6391a02fdc68c1a0fb261d2ca5b77? We changed some things about dynamic loading there. Maybe this is where problems were introduced...

[mferrero]

One more thing: if you just type

from pytriqs.boost.mpi import *

from a pytriqs shell, do you get the error as well? Or do you need to have imported some other stuff earlier?

[aeantipov]

This works fine.

With the older version ( 3f9cfa347700f2bb93b40dd641920130b2f73a79 - the one prior to that commit ) I get

[ 56%] Building CXX object triqs/arrays/test/C++/CMakeFiles/a_x_ty_nopy.dir/a_x_ty.cpp.o

[parcollet]

Even more bizarre ... Can you try going a bit few commits earlier (git co ...). It is quite hard for us to track this down since we can not reproduce it (we don't have icc 12 here anyway). What is your mpi libs ? Can you make an ldd of the .so modules ? On the mac, we already had bizarre problems due to mixing compilers (different versions of gcc, etc...) and glibc (I worry about having libmpi using some glibc, icc some other...)

[aeantipov]

Sorry, next week I'm not here, will try to test it more. Will write down what I receive.

While I was out there was some change in hardware. Obtained a successful compilation of triqs with clang and mkl on macos x64 arch!
