01:57 < rcurtin> fristonio: sorry for the slow response. is it possible to paste the full output of what happens when you type 'make python'?

11:33 < fristonio> Hi, so I have been trying to install mlpack, and while I can use the binaries from within the bin folder, I am having trouble calling mlpack from within the python interpreter. It's giving me a module not found error. I have tried following along the steps of issue # 1416, but that doesn't seem to be the solution. All the depedencies (cython, numpy) have their latest versions. I cannot figure out what's going wrong

11:34 < fristonio> I am on Manjaro, it's an Arch based distribution

11:35 < zoq> fristonio: Hello, can you post the output of 'make python' as Ryan suggested yesterday: http://mlpack.org/irc/

11:37 < fristonio> sure just a second

11:38 < fristonio> https://pastebin.com/Jq0QJink

11:44 < zoq> okay that looks good, can you post the output of 'make install' as well?

11:45 < fristonio> np

11:49 < fristonio> it's going to take some time, it isn't giving the normal "built" messages but it's actually building them now

11:51 < zoq> okay, this might take some time

12:07 < fristonio> okay do you want the whole log? It threw an error at the end

12:08 < fristonio> https://pastebin.com/Q9MbPHUF

12:09 < fristonio> I should have probably made the terminal output the log into a file, I am sorry I just ran it on the terminal, I can't scroll all the way back up now

12:11 < fristonio> the first time I ran this command (during the initial setup) I had run "sudo make install" so I guess this explains the error I am getting now,

12:11 < fristonio> ?

12:14 < fristonio> https://pastebin.com/UmF5E6ah

12:15 < fristonio> this is the whole output, I assume, I piped it into a file

12:23 < zoq> okay, this looks good as well

12:24 < zoq> did you test the import after the last make install?

12:24 < fristonio> that error went away when I ran make install as root, however still no change cannot import mlpack into python interpreter :(

12:24 < fristonio> python 3.7.0 if this helps

12:27 < fristonio> cli interface works great, I can run commands, test it out on datasets, call "help" on it, it's just not getting imported into python. I added all the env variables which had been specified on the online doc, in my zshrc profile

12:27 < fristonio> in short all the intsructions have been carried out

12:28 < zoq> hm, okay, can you also print your PYTHONPATH, 'os.environ['PYTHONPATH'].split(os.pathsep)'?

12:29 < zoq> it should list: /usr/lib/python3.7/site-packages

12:30 < fristonio> ['', '~/Downloads/builds/mlpack-3.0.3/build/src/mlpack/bindings/python/']

12:30 < zoq> what about 'print(sys.path)'

12:31 < fristonio> ['', '/home/himal', '/home/himal/~/Downloads/builds/mlpack-3.0.3/build/src/mlpack/bindings/python', '/usr/lib/python37.zip', '/usr/lib/python3.7', '/usr/lib/python3.7/lib-dynload', '/usr/lib/python3.7/site-packages']

12:33 < fristonio> wait, why is the "~" getting repeated in the 3rd item?

12:33 < fristonio> yeah I changed it to no effect

12:33 < zoq> I guess ls /usr/lib/python3.7/site-packages/ does show mlpack

12:34 < zoq> we are using the packages from /usr/lib/python3.7/site-packages/ anyway

12:34 < zoq> so you could remove the build folder

12:35 < fristonio> ls /usr/lib/python3.7/site-packages has NO mlpack,

12:36 < fristonio> I think we found the problem

12:37 < zoq> what about /usr/local/lib/python3.7/site-packages?

12:38 < fristonio> mlpack-3.0.3-py3.7-linux-x86_64.egg: this is present

12:39 < zoq> okay, can you add /usr/loca/lib/python3.7/site-packages to your PYTHONPATH?

12:41 < fristonio> worked

12:41 < fristonio> great

12:41 < fristonio> thanks a lot

12:43 < zoq> great, I guess there is a way to either use /usr/lib right away or to extend the PYTHONPATH automatically

12:43 < zoq> will look into it

12:43 < fristonio> thanks, that's great

15:31 < rcurtin> fristonio: zoq: also possible is to set -DCMAKE_INSTALL_PREFIX=/usr to install directly to /usr/lib not /usr/local/lib but that could cause conflicts between manually installed files and system installed files

15:38 < zoq> rcurtin: Right, I was thinking if we could check the PYTHONPATH at the install or build step and print some information based on that at the end e.g. add /usr/local/lib... to your PYTHONPATH

15:48 < rcurtin> I think that would be a good idea
