yolo_init should not change the working directory

[sunsided]

In libyolo.c's yolo_init function here, the code is doing a chdir to the darknet directory. This massively impacts the calling code that assumes its working directory is actually the directory it is started in. Is there a way to not change the directory?

Darknet find file by relative path. If you want not change directory, you should modify darknet code.

Could we at least chdir back to where we came from?

I added Darknet path parameter. You can run pyyolo outside of directory.

@thomaspark-pkj Thanks for the path update However, I encounter two problems when I installed the new version. Originally, I have installed pyyolo in two separate directory for some purpose. I think they points to the same "pyyolo-0.1-py2.7.egg-info"(which I didn't aware before), not sure how it works, but they both function properly.

So today, I tried to update one of them to the latest version and build it. It installed/build properly, however problems happen when i run the "example.py"

1. I have checked the new clone has "darknet_path" in [email protected] , however

Traceback (most recent call last):
  File "example.py", line 20, in <module>
    pyyolo.init(darknet_path, datacfg, cfgfile, weightfile)
TypeError: function takes exactly 3 arguments (4 given) 

2. When I try to run the older version with "example.py" in another directory, segmentation fault 11 appears. Which I tried to re-install/build the older version, same error returns.

----- test python API using a file
Reading data/person.jpg
Segmentation fault: 11

In older version, segmentation happens on image size > 698196 only, example image "person.jpg" is always fine. But now "person.jpg" trigger the same problem too, which I totally can't use pyyolo now.

FYI, I do think this error is correlated with this two post I replied before. segmentation error Import Error, AttributeError: 'module' object has no attribute 'init'

I think example.py refer old library. Could you clean previous module then rebuild all?

@thomaspark-pkj Sorry for another question. I had tried to clear the build inside pyyolo but it seems not working. I had remove pyyolo.so and pyyolo-0.1-py2.7.egg-info as well. Still not working at all. Is there any more hidden path i should know???????

=========================================================== I have just solved the problem!!!! I tried to grep search "pyyolo.so" but not sure y it just loading but not response. Therefore, I go for searching "sys.path" one by one. Turns out, I found out there is another pyyolo.so installed in another site-packages directory which was not shown when you run "python setup.py install". I remove that and re-build the whole stuff it works now!! I can call the library outside the directory now! Thanks a lot!!
