[mlpack] issue with mlpack Python bindings on Mac OsX

[Frodo Jedi]

Dear list members,
I am unable to properly install the python bindings, despite I correctly
built mlpack from source without any error and warning. I am on a Mac OsX
10.12.6 and all the dependencies have been installed with the latest
available version. I am also using the latest version of Cmake.

Looking at this thread, where the same issue was reported,
https://github.com/mlpack/mlpack/issues/1416 , I get that mlpack should be
installed in
/usr/local/lib/pythonX.Y/site-packages/ However it is not present.

As a result when I try to import the module in python 2 or 3 I get
>>> import mlpack
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named mlpack


I even tried to manually launch from the build directory the commands

export LD_LIBRARY_PATH=lib/
export PYTHONPATH=src/mlpack/bindings/python/

but with no improvement.


In /lib I have the files libmlpack.3.0.dylib* libmlpack.3.dylib@
 libmlpack.dylib@
should I manually move them? Where exactly?


Any suggestions? What I am missing?

Also, I signal that I get the following errors when running the test:

bin/mlpack_test

*** 5 failures are detected in the test module "mlpackTest"



Finally, I signl that pip install mlpack/mlpack3 does not work.
