Can anyone help me with this? I'm trying to get the IDL-python bridge up and running on my Mac (10.11.4). I have idl 8.5 and python 2.7 from anaconda (installed yesterday).

I've exported the following paths
export PATH=" /Users/joellama/anaconda/bin:/Applications/exelis/idl/bin/bi n.darwin.x86_64:$PATH "
DYLD_LIBRARY_PATH="/System/Library/Frameworks/ImageIO.framework/Resources "
DYLD_LIBRARY_PATH="$DYLD_LIBRARY_PATH:/Users/joellama/anaconda/lib "
DYLD_LIBRARY_PATH="$DYLD_LIBRARY_PATH:/usr/lib"
DYLD_LIBRARY_PATH=" $DYLD_LIBRARY_PATH:/Applications/exelis/idl85/bin/bin.darwin .x86_64 "
export DYLD_LIBRARY_PATH
export LD_LIBRARY_PATH=" /Users/joellama/anaconda/lib:/Applications/exelis/idl/bin/bi n.darwin.x86_64 "
export PYTHONHOME="/Users/joellama/anaconda"
PYTHONPATH=" $PYTHONPATH:/Applications/exelis/idl85/bin/bin.darwin.x86_64 "
PYTHONPATH="$PYTHONPATH:/Applications/exelis/idl85/lib/bridges "
export PYTHONPATH

and if I run IDL and type

ran = Python.Import('numpy.random')

I get
% Loaded DLM: PYTHON27.
ImportError: numpy.core.multiarray failed to import
% PYTHON_IMPORT: Exception: cannot import name multiarray.
% Execution halted at: $MAIN$

and if I run ipython and type

import idlpy as IDL

I get

ImportError Traceback (most recent call last)
<ipython-input-1-2e8893d7bd77> in <module>()
----> 1 import idlpy as IDL

/Applications/exelis/idl85/lib/bridges/idlpy.py in <module>()

both exist. Any help would be greatly appreciated!

I get same issue but with homebrew install if python on both 2.7 and 3.4 (adjusted the environment variables accordingly). Have you tried reaching out to Excelis?

Hello there,

I tried to set up the IDL-python bridge on my mac and I got the same error (I installed IDL 8.5.1 and python is pre-installed on my macOS Sierra 10.12.2). When I typed

np = Python.Import('numpy')
The error messaged popped out as:

% DLM_LOAD: Error loading sharable executable.
Symbol: IDL_Load, File = /Applications/exelis/idl85/bin/bin.darwin.x86_64/idl_python2 7.so
dlopen(/Applications/exelis/idl85/bin/bin.darwin.x86_64/idl_ python27.so, 1): Library not loaded: libpython2.7.dylib
Referenced from: /Applications/exelis/idl85/bin/bin.darwin.x86_64/idl_python2 7.so
Reason: image not found

It looks like you also ran into the libpython2.7 dylib Libarary not loaded issue. I was wondering if you have fixed that.

Cheers,
Huazeng

Hi,
I ran into the same issue for python 2.7 (pre-installed on macOS 10.12.2):

libpython2.7 dylib Libarary not loaded

Have you already fixed it?

Cheers,
Huazeng
