Error running run_faster_rcnn.py

[Annakj97]

• I tried to run the first Example on: https://github.com/microsoft/CNTK/tree/master/Examples/Image/Detection/FasterRCNN
• everything worked until i tried 'python run_faster_rcnn.py'
• Im working in a Ubuntu 18.04 virtuel machine (VMware)
• The CNTK enviroment was created like this: https://docs.microsoft.com/en-us/cognitive-toolkit/Setup-Linux-Python?tabs=cntkpy27
• MPI was installed with this command: sudo apt-get install openmpi-bin
• Any idea what went wrong?

The Errormessage:

Traceback (most recent call last): File "run_faster_rcnn.py", line 9, in import cntk File "/home/anna/.local/lib/python2.7/site-packages/cntk/init.py", line 27, in from . import cntk_py File "/home/anna/.local/lib/python2.7/site-packages/cntk/cntk_py.py", line 21, in _cntk_py = swig_import_helper() File "/home/anna/.local/lib/python2.7/site-packages/cntk/cntk_py.py", line 20, in swig_import_helper return importlib.import_module('_cntk_py') File "/usr/lib/python2.7/importlib/init.py", line 37, in import_module import(name) ImportError: libmpi_cxx.so.1: cannot open shared object file: No such file or directory

OpenMPI 1.10 is expected. Apt-get may install v2.0, you should check it to make sure

Hi, thanks for the answer. I had v2.0 installed. Now I installed 1.10 like this: http://butka.me/linux/how-to-install-openmpi-on-ubuntu-14-04/ But again I have the exact same Errormessage.

You have to add the path to libmpi in PATH or LD_LIBRARY_PATH in .bashrc

Edit: after that try "mpiexec" from terminal. If it's not callable then your PATH has not been set up successfully.

however, why would you run it in ubuntu when CNTK run perfectly fine in window..?
