Problem with plmDCA

[aai97]

When I try to import plmDCA in python, as described in the readme, I get an error:

import plmDCA

Exception caught during initialization of Python interface. Details: Could not find an appropriate directory for MATLAB or the MATLAB runtime in LD_LIBRARY_PATH. Details: libmwmclmcrrt.so.9.4

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

  File "home/prospr-master/potts-code/plmDCA/__init__.py", line 280, in <module>
    _pir.get_paths_from_os()

  File "home/prospr-master/potts-code/plmDCA/__init__.py", line 182, in get_paths_from_os
    self.path_var, file_to_find))

RuntimeError: Could not find an appropriate directory for MATLAB or the MATLAB runtime in LD_LIBRARY_PATH. Details: libmwmclmcrrt.so.9.4

I also realized that in my matlab directory I do not have an X11-directory, the one we are supposed to save as the environment variable XAPPLRESDIR.

Does anyone have a clue what could be the problem?

Did you add the path to you Matlab Runtime to your LD_LIBRARY_PATH variable?

export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/local/MATLAB/MATLAB_Runtime/v94/runtime/glnxa64:/usr/local/MATLAB/MATLAB_Runtime/v94/bin/glnxa64:/usr/local/MATLAB/MATLAB_Runtime/v94/sys/os/glnxa64:/usr/local/MATLAB/MATLAB_Runtime/v94/extern/bin/glnxa64

You may have to adapt the path

I think I must have tried at least a dozen times doing that. Unfortunately it did not help.

Same problem here, and I tried the same methods. Didn't work.

Did anybody have suggestions regarding this?

Thanks for any help

I had the same problem and I solved by installing Matlab runtime and following the guideline in 7/otts-code/readme.txt. It works locally when I import the plmDCA but if I am running prosper from the docker it complains. Any suggestion is more than welcome :)

I am also running the program by using singularity rather than docker since it is the only one supported by our IT service.
This is the error that I got:
