mpi4py import error

[nithyan...@gmail.com]

Hi,

I have been trying to install and get mpi4py running on a Linux machine. Before installing mpi4py, I checked that MPI, mpicc, etc. were installed on the machine. I installed mpi4py using pip and also using the setup.py methods under a virtual environment separately and got the same results. The installation seemed to go OK. When I opened any interpreter, python or ipython, and tried to import MPI using:
from mpi4py import MPI, I got the following fatal error:

I have tried to find more information from this group on this error. In particular, I read up the discussion here: https://groups.google.com/d/topic/mpi4py/Puv4BHqQ4qY/discussion
and the sections 3.1 and 5.1 in http://mpi4py.scipy.org/docs/mpi4py.pdf
and tried installing a python2.7-mpi interpreter. I find myself stuck with the same error upon invoking python2.7-mpi

I get the same errors if I use mpirun on a test python code from the command line as well. I do not have system administrator privileges but I could get some assistance if I have some strong leads on how to proceed and if it requires administrative privileges to fix this error.

Any help would be greatly appreciated. 

Thanks,
Nithya

Could you try to run

$ ldd /path/to/mpi4py/MPI.so

where /path/to is where mpi4py was installed?

Also, what Open MPI version are you running?

When the python2.7-mpi fails? Immediately after invoking it? Are you
able to get the python prompt?

Before anything, please try this:

$ wget https://bitbucket.org/mpi4py/mpi4py/raw/master/demo/helloworld.c
$ mpicc helloworld.c -o helloworld.exe
$ mpiexec -n 4 $./helloworld.exe

Does it produce the expected output?

Hi Lisandro,

Thanks for your reply.

Could you try to run

$ ldd /path/to/mpi4py/MPI.so

where /path/to is where mpi4py was installed?

This is the output of running ldd on MPI.so:

Also, what Open MPI version are you running?

The man page on mpicc says it is version 1.4.3. Is that the version number the right one you wanted?

able to get the python prompt?

The python2.7-mpi fails right after invoking and it does not get to the python prompt.

Hi Aron,

Yes, the base MPI does appear to be broken. Any ideas or pointers on diagnosing it would be very helpful. Or would you suggest a fresh install?

You can use hashdist to install a local mpich, Python, and mpi4py. What os are you on?

My diagnostics on you issue is that your system has both MPICH and
OpenMPI packages installed, and they are conflicting. To solve it the
proper way, you need root, or just ask your sysadmin to fix the mess.
Alternatively, you can install MPICH or OpenMPI in your home directory
(make sure you configure MPICH to use shared libraries).

[Aron Ahmadia]

Hi Nithya,

I’ve put up a sample mpi4py profile here: https://gist.github.com/ahmadia/9782416

You should be able to use it, assuming you have gcc, make, git, by following the instructions below. # are comments that aren’t used by shell.

# first, get a copy of the hashdist repository
git clone https://github.com/hashdist/hashdist
# then, get a copy of the profile you'll be using
wget https://gist.githubusercontent.com/ahmadia/9782416/raw/0e79b4003c0a444012569ff33b59d2429734c8ce/mpi4py.yaml
# alternatively, you could use: curl -O or download the file by hand
# now, use hashdist to build your profile, you can add the "-v" flag if you want to see all the details of the build
# you'll see hashdist download and build an openblas, numpy, mpich, python, and finally an mpi4py
./hashdist/bin/hit build mpi4py.yaml

# now you can start up the Python with mpi4py ready to go
./mpi4py/bin/python

You’ll find the mpicc and other tools you need in ./mpi4py/bin.

A couple warnings, this profile installs a Python, MPICH, and OpenBLAS for you. This is a bit redundant if you already have working versions of these on your system, but they are guaranteed to work, which is useful :)

Let me know if this works out for you, and if not, I’m happy to try and assist.

Cheers,
Aron

Hi Lisandro and Aron,

Before I proceed with a local copy of python and MPICH, I'd like to mention that I have virtual environments set up. Does it mean that in order to use the local copy of python, I have to set up another set of virtual environment again? Or can only the local MPICH and mpi4py be set up locally without another local python but use the already existing python?

Thanks,
Nithya

[Aron Ahmadia]

You can treat the local python build like a virtual environment. It's designed to be easily modified and support parallel environments. Hashdist can support using your system python as well but it is not as simple.

Hi Aron,

I've spoken to our group and we felt it might be better to have a clean MPI install for all the user and hence we've removed the conflicting MPICH and subsequently went ahead with an OpenMPI install.

The "hello world" program runs successfully and I've gone on to install mpi4py which also seems to be working well. Would you say that all is well now or should I test it a bit further? Since I'm new to MPI programming, any test scripts would be very useful.

In summary, we've decided to stick to a system-wide MPI and I wouldn't need to do install anything locally. Thanks for all the help. You guys have been very helpful in tracking down and fixing my MPI issues.

You can test mpi4py more aggressively by cloning the repository from https://bitbucket.org/mpi4py/mpi4py and then running:

mpiexec -n 5 python test/runalltest.py

Oops, you should test the version that you installed.  So you should download the release corresponding to whatever you installed.

I installed mpi4py v1.3.1 and found no file named runalltest.py under the test directory. I did find a file named runtests.py. But I wasn't sure what the inputs for these tests are. So I just ran it without inputs and found these results (I had just renamed runtests.py to MPI_runtests.py). Naturally because I gave no inputs, 0 tests were run. Let me know if I should give specific inputs.

It's not, but it looks like you've got a mostly-functional MPI.  You can get more information about the error by using a `-v` flag to runtests.py.

With the -v flag, this is what I get. I hope this isn't too bad that I can't get anything going.

Just a bit curious why it worked the first time but not subsequently.

Lisandro might have a better idea.  I don't recognize the error, it just looks like one of the allgather or intercommunicator tests is failing.  Thanks for reporting the issue, you can try digging in to the test code with a debugger and see if you can figure out exactly what is failing and why, but it's likely that this problem won't affect you.

I appreciate very much your help and Lisandro's in getting MPI running via python. I'll leave it to you experts to figure out what could be the issue with the failed test.

Once again, thanks a lot!

Well, the Open MPI version you are used is quite aged. I'm not sure
what the exact error you got is, but it seems you have a functional,
working mpi4py. mpi4py's test suite have helped to find minor issues
in MPI implementations, and these issues are fixed in newer Open MPI
releases.

[Nithyanandan Thyagarajan]

I posted the output after using -v flag. If the error is still too cryptic, let me know if I can run something very simple to further narrow it down.
Yes, I think the mpi4py I have now is functional for my purposes and I am happy with it so far.
