Error running run_faster_rcnn.py

Annakj97 commented 5 years ago

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.
