#42 Problem when running in MacOS

[Rafael Barfknecht]

Hello all,

I have just performed a (global) installation of openMPS (v3.1) on macOS. Everything ran apparently smoothly, but when I tested

python3 Examples/01_IsingStatics.py --PostProcess=False && \
python3 Examples/01_IsingStatics.py --PostProcess=True

I got

Execute_MPSMain TMP_01/Ising_Staticsg_0.0Main.nml 0
/bin/sh: Execute_MPSMain: command not found
Traceback (most recent call last):
File "Examples/01_IsingStatics.py", line 118, in <module>
main(PostProcess=Post, ShowPlots=Plot)
File "Examples/01_IsingStatics.py", line 77, in main
mps.runMPS(MainFiles, RunDir=RunDir)
File "/usr/local/lib/python3.7/site-packages/MPSPyLib/tools.py", line 398, in runMPS
raise MPSFortLibError(ret_val)
MPSPyLib.tools.MPSFortLibError: MPSFortLib quit with fatal return code 127!</module>

which I know is a common error that I solved (on Linux) by removing the ./ from the RunDir = './' line in the codes. Here, however, that did not work. I have installed openblas, lapack and openmpi with brew install instead, which is not exactly the same as given here

https://sourceforge.net/p/openmps/wiki/OpenMPS%20from%20Source/

but that does not seem to be the problem. All other dependencies were installed with pip3 as recommended.

Any thoughts?

Best wishes,

Rafael

Hey Rafael,

Error code 127 typically indicates the compiled executable could not be found or is not executable. In the most recent changes to OpenMPS, we added logical blocks as follows (for some context)

    # Run the simulations and quit if we are not just Post
    if(not PostProcess):
        if os.path.isfile('./Execute_MPSMain'):
            RunDir = './'
        else:
            RunDir = None
        mps.runMPS(MainFiles, RunDir=RunDir)
        return

If the MPS executable is not found in the current working directory, we override RunDir to None, forcing OpenMPS to assume a global installation.

To the issue you're having, can you send me the logs from your compilation/installation? They should be in the OpenMPS root directory, a file called make.log. I'm attaching a sample log so that you know what to look for.

Hi Matthew,

Thanks for the reply. I am not specifying any type of local installation. The make.log file is attached.

Best wishes,

Rafael

Thanks, Rafael! It looks like ARPACK wasn't found. Do you have it installed?

If so, simply update the install command to add the library path for ARPACK marked by *** below.

python BuildOSMPS.py --prefix=$CONDA_PREFIX/bin \
                     --option=FC:x86_64-conda_cos6-linux-gnu-gfortran \
                     --option=INCFLAGS:-I$CONDA_PREFIX/include \
***     --option=LIBFLAGS:"-L$CONDA_PREFIX/lib -L/path/to/libarpack"

[Rafael Barfknecht]

Hi Matthew,

Thanks for the reply. I have arpack 3.7.0_3 installed already.

Then I ran

sudo python BuildOSMPS.py --prefix=$CONDA_PREFIX/bin
--option=FC:x86_64-conda_cos6-linux-gnu-gfortran
--option=INCFLAGS:-I$CONDA_PREFIX/include
--option=LIBFLAGS:"-L$CONDA_PREFIX/lib -L/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/scipy/sparse/linalg/eigen/arpack"

but I still got errors (see the make.log file attached).

Any ideas?

Rafael

I think I've found the problem. Can you run a quick command in terminal? See below. Each should be run as a separate command, and the output should be pasted in a reply.

which python
python --version ... note: this should be Python version 3+. Python version 2 is formally deprecated. If you need help updating your version of Python, let me know in your reply, and I'll post some options.
which gfortran ... note: if GNU is not supplying the Fortran compiler, please change "gfortran" to the Fortran compiler you intend to use.
ls -la /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/scipy/sparse/linalg/eigen/arpack

What package manager are you using to acquire dependencies? Is it just pip?

A note about the command I sent before: this was not clear, but the paths for the various options need to be updated on your system. The command before assumed you were using Anaconda to acquire pacakges. I'll improve the clarity on the Wiki, and break out more sections.

python BuildOSMPS.py --prefix=/path/to/your/binary-executables \
                     --option=FC:/path/to/your/fortran-compiler \
                     --option=INCFLAGS:-I/path/to/your/system/includes \
***     --option=LIBFLAGS:"-L/path/to/your/system/libraries -L/path/to/libarpack/if/not/in/system/libraries"

Hi Matthew,

Thanks for the reply. I have installed the dependencies with brew, I believe.

In regard to the commands:

which python
/usr/bin/python

python --version
Python 2.7.16

But python3 is installed

python3 --version
Python 3.7.7

which gfortran
/usr/local/bin/gfortran

ls -la /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/scipy/sparse/linalg/eigen/arpack

Hi Rafael,

Bumping this thread.
I've updated the conda environment preparation scripts to support macOS.

Would you mind running through the new instructions, and letting me know if they address your problem?

Instructions link.

Hi Matthew,

Thanks for the update.

I managed to create the conda environment and run

python setup.py install

without apparent problems, but when running

python BuildOSMPS.py --prefix=/Users/rafaeleb/anaconda3/bin

I get the following error:

Fatal Error: Can't open module file 'ieee_arithmetic.mod' for reading at (1): No such file or directory
make[1]: [/Users/rafaeleb/Documents/openmps/MPSFortLib/Mods/Tensors.o] Error 1
make: [moddir_obj] Error 2
mv MPSFortLib/make.log .

[Matthew Jones]

Hi Rafael,

Please try the following (from OPENMPS_ROOT):

conda activate openmps && \
rm -rf build && python BuildOSMPS.py --clean && \
python setup.py install && \
python BuildOSMPS.py --prefix=$CONDA_PREFIX/bin \
                     --option=FC:$CONDA_PREFIX/bin/gfortran \
                     --option=INCFLAGS:-I$CONDA_PREFIX/include \
                     --option=LIBFLAGS:-L$CONDA_PREFIX/lib

If this does not work, please send me the make.log and the exact command sequence you're using to compile the project.

Hello Matthew,

I run

conda activate openmps
rm -rf build && python BuildOSMPS.py --clean
python setup.py install

and it works fine up to here. For

python BuildOSMPS.py --prefix=/Users/rafaeleb/anaconda3/bin

I still get an error (Fatal Error: Can't open module file 'ieee_arithmetic.mod' for reading at (1): No such file or directory make[1]). See the log attached.

It doesn't look like you've run the build command I sent above.
The additional options are necessary as they tell Fortran where to look for certain libraries.
The error you're getting is telling you that the Fortran compiler cannot find a system-installed module.

Can you try running the command I sent, and report back?

[Matthew Jones]

Hi Rafael,

Did we get this problem fixed?

I went through your logs again, and noted that the issue is the fortran compiler (it's too old).

Let us know how we can help,
Matt
