CMake Error at cmake/FindPLY.cmake:24 (message): ply import failure: #3149

Hello, Under a ubuntu 14.04 64bit,I tried to compile shogun from source,but got error:

...
-- Could NOT find MOSEK (missing:  MOSEK_DIR MOSEK_INCLUDE_DIR MOSEK_LIBRARY) 
.....
-- Could NOT find CPLEX (missing:  CPLEX_LIBRARY CPLEX_INCLUDE_DIR) 
.....
CMake Error at cmake/FindPLY.cmake:24 (message):
  ply import failure:

Call Stack (most recent call first):
  CMakeLists.txt:682 (FIND_PACKAGE)

Questions are: Do these two "Could NOT find"s cause this error? if there are,how to install them?(as you may knew,by default,much more "Could Not find"s will occur,and I have installed these missings by googling,but can't find a way to install these two)

Is "ply import failure:" the only reason that caused this failure?If it is,how to fix it?It seems that no solution can be found by googling?

If "ply import failure:" do cause the problem,after fixed it,can I ignore the two "Could not find"s to install?any consequence?

Hey!

You just need to install python-ply, using sudo apt-get install python-ply. The other two (MOSEK, CPLEX) can be safely ignored.

Cheers Björn

I improved the situation in https://github.com/shogun-toolbox/shogun/commit/d2e1beacd9a156be2fb50c6c5f12269508224cab It now tells the user to de-activate meta examples or install ply

Sorry for interrupting, I met the issue "Python module ply required for meta examples. Disable meta examples or install python-ply" even if I installed the python-ply. What does the "meta example" mean?

karlnapf commented 7 years ago

It is these guys: shogun.ml/examples

If you want to generate the code for those locally, you need ply. If you have it installed and it is not detected, please send a report with details of your setup in a new issue.
