Python: ImportError: No module named libbgs

[Insaf-Setitra]

Hello,

I have compiled the library using:

git clone https://github.com/andrewssobral/bgslibrary.git
cd build
cmake -D BGS_PYTHON_SUPPORT=ON ..
make

no errors in making, added to the python path:

`>>> import sys

from pprint import pprint as pp
pp(sys.path)
['',
'/home/user/bgslibrary/build/libbgs.so',
'/home/user/bgslibrary',
'/usr/lib/python27.zip',
'/usr/lib64/python2.7',
'/usr/lib64/python2.7/plat-linux2',
'/usr/lib64/python2.7/lib-tk',
'/usr/lib64/python2.7/lib-old',
'/usr/lib64/python2.7/lib-dynload',
'/usr/lib64/python2.7/site-packages',
'/usr/lib/python2.7/site-packages']`

I tried many adds into the path: 'libbgs.so', '/home/user/bgslibrary/build/libbgs.so', '/home/user/bgslibrary',

But still have the error :
[user@localhost bgslibrary]$ python Demo.py
Traceback (most recent call last):
File "Demo.py", line 3, in
import libbgs
ImportError: No module named libbgs

OS: Fedora 25

Any suggestions?

Thanks,

I have the same problem, have you solved it? @fasni

[kaisark]

@fasni You need to point to the build directory where you made the bgslibrary software:

export PYTHONPATH="${PYTHONPATH}:$HOME/myapps/bgslibrary/build"

Same problem. Sometimes it works, but most of the time I can't import module

[zuenko]

import sys
sys.path.append('/home/denis/bgslibrary/build')

Pointing doesn't work fine for me, but this lane into your code help me to execute it anywhere.

Now with the migration to pybind11 I think this issue was solved

[potoo0]

It's works.
Add this at the top of script.

import os
import sys
sys.path.append(os.getcwd() + '/build')

Same here even i tried all the above solutions. Which file from build folder is needed ?

Well, you can backup the original folder and delete some files for testing.
According to my tests, following files are required:

bgs.cp36-win_amd64.pyd
bgs.exp
bgs.lib
bgslibrary_core.dll
bgslibrary_core.exp
bgslibrary_core.lib

And, .vs is a hidden folder under the bulid folder, which takes up quite a bit of disk.
