Import Error, AttributeError: 'module' object has no attribute 'init'

[AndyTsangChun]

I was trying to import the pyyolo wrapper from a parent directory.

However, I encounter this error
File ".../pyyolo/body_detector.py", line 18, in __init__ pyyolo.init(datacfg, cfgfile, weightfile)
AttributeError: 'module' object has no attribute 'init'
I am aware that some path was set by the setup.py, which causing the "pyyolo" module can only be import properly within the directory.

I also used the "imp" module and found that the module outside the directory looks like
>>> imp.find_module('pyyolo') (None, 'pyyolo', ('', '', 5))

While inside the directory look like
(<open file '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pyyolo.so', mode 'rb' at 0x1005d4a50>, '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pyyolo.so', ('.so', 'rb', 3))

However, even I tried to use the "imp" module to import it with the path above still nth happens. Its there any other way I can use/import the wrapper from parent directory????

Thanks a lot!!!

Sorry. I cannot know the reason. Could you rebuild all after removing 'build' directory?

[AndyTsangChun]

Rebuilt serval times, still having the same problem
I tried other method of importing or path setting still not works.
e.g.
sys.path.insert(0, '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages')
or
sys.path.append("/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages")
But I believes, it must be some sort of path setting problems??

Could you share Makefile and build process?
pyyolo module should be in python2.7/dist-packages.

[AndyTsangChun]

Attached my Makefile and build logs.

Not sure what I added in the last couple hours but the error actually changed to
Couldn't open file: pyyolo_lib/cfg/coco.data

However, I believe I have the correct path to the file,
cuz when I run inside the pyyolo directory
os.getcwd() >> bababaMyComputer/myproject/pyyolo_lib
datacfg = 'cfg/coco.data'
This works fine.
but when I run outside the pyyolo directory (import the example.py)
os.getcwd() >> bababaMyComputer/myproject
using datacfg = 'pyyolo_lib/cfg/coco.data'

====================================================

Another changes I just made is
By user_paths = os.environ['PYTHONPATH'].split(os.pathsep)
I found that the programs was pointing to
/Library/Python/2.7/site-packages->> PATH 1
and
/usr/local/lib/python2.7/site-packages ->> PATH 2

But the .so was placed in
/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages ->> PATH 3

Although both inside or outside the directory points to the same PATH 1 & 2 only
Inside the directory will finds it and works fine?? Not sure why

I have tried to cp the .so and egg-info to PATH 1 & 2, however, due to the error switched to couldn't open file:coco.data. I am not sure does it fix the path stuff yet

You should use absolute path when you run outside of pyyolo directory.
Path is something like macOS. I'm not tested on mscOS.

[AndyTsangChun]

You mean I need the absolute path for the coco.data?
Well I have tried that.
It appear another file not found coco.names which I guess is set within the pyyolo.so?
Cuz i don't find anywhere I can change it in example.py

Here is part of the code I use to select the path for the files. Just for testing with two cmd(inside and outside the directory). But I doubt this part is affecting coco.names?

cfgfile = 'cfg/tiny-yolo.cfg'
weightfile = '../tiny-yolo.weights'
ospath = os.getcwd().split('/')
if not ospath[len(ospath)-1]=='pyyolo_lib':
	datacfg = os.getcwd() +'/'+ 'cfg/coco.data'
	cfgfile = os.getcwd() +'/'+ 'cfg/tiny-yolo.cfg'
	weightfile = os.getcwd() +'/'+ 'tiny-yolo.weights'```
