Could not load any ArrayFire libraries

[ivan-gusachenko]

Hello,
I'm sorry I know this issue has been around for a while but I couldn't solve it based on the posted solutions. I'm trying to install it for Mac OSx with cpu and opencl, without cuda. So I write this in the terminal:
export DYLD_LIBRARY_PATH=/usr/local/lib:$DYLD_LIBRARY_PATH
as this is where my libaf*.dylib files are located. Still, when trying to import the module I get this message:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/ivangusachenko/anaconda/lib/python3.6/site-packages/arrayfire/__init__.py", line 56, in <module>

    backend = _clibrary()
  File "/Users/ivangusachenko/anaconda/lib/python3.6/site-packages/arrayfire/library.py", line 576, in __init__
    raise RuntimeError("Could not load any ArrayFire libraries.\n" + more_info_str)

@ivan-gusachenko Something about conda may be screwing up the DYLD_LIBRARY_PATH. Can you try using arrayfire using regular python?

[ivan-gusachenko]

Thank you,
I've just tried as you said, but unfortunately this didn't help.

@ivan-gusachenko can you try running otool -L /usr/local/lib/libaf.dylib and showing the output?

[ivan-gusachenko]

Thanks, it gives:

@ivan-gusachenko how did you install arrayfire ? Do you have libforge present in /usr/local/lib ?

[ivan-gusachenko]

Big thanks for you guidance, Pavan.
I do have libforge, libforge.1, and libforge.1.0.2 in /usr/local/lib

First, I installed Anaconda.
Then I installed homebrew by doing this:
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
then I downloaded binaries for Mac OS from arrayfire.org, and followed the installation procedure.
Then I downloaded a cmake installer package for Mac OS and installed it, but apparently this didn't work. So I also installed cmake from brew:
brew install cmake.
Arrayfire recommended cmake, but I don't think there's connection with python here.

Then, from terminal, I installed arrayfire-python:
pip install arrayfire
Then I tried to make it work by changing the lib path for DYLIB variable, to no avail.
Then, after your advice, I switched to the system preinstalled python distribution by removing conda directory from PATH variable, and then I had to reinstall arrayfire-python by
pip install arrayfire
Every often I check export to make sure I have /usr/local/lib in my DYLIB var.

@ivan-gusachenko I think some dependency for libforge is not present on the system ?

Can you run otool -L libforge*

sorry I don't know how to preserve the original formatting when pasting

[pavanky]

@ivan-gusachenko I have been editing your comments to fix the formatting. You are using a single tick (used for quoting) instead of three ticks (used for showing code).

[pavanky]

@ivan-gusachenko can you uninstall the current version of arrayfire and try installing the following:

http://ci.arrayfire.org/userContent/OSX/ArrayFire-no-gl-v3.5.0_OSX.pkg

[ivan-gusachenko]

Sorry, could you please tell how to uninstall it? There's no uninstaller, and its files are now all over the place, in different directories. However, when I just launch the file you've provided, the default option is to 'upgrade' all the components. Would it be OK to let the .pkg installer handle the upgrade, instead of a clean uninstall/install? Thank you
