Darknet: OSError: ./libdarknet.so

Created on 12 Feb 2019 · 4Comments · Source: AlexeyAB/darknet

I try to work with Yolo v3 using python script darknet.py
Then I run
python darknet.py

I got
Traceback (most recent call last):
  File "darknet.py", line 122, in <module>
    lib = CDLL("./libdarknet.so", RTLD_GLOBAL)
  File "/home/y700/anaconda3/lib/python3.7/ctypes/__init__.py", line 356, in __init__
    self._handle = _dlopen(self._name, mode)
OSError: ./libdarknet.so: cannot open shared object file: No such file or directory

I found informations about at first need set values LIBSO to 1 and make new make. But nothing change. After I try bash script
LD_LIBRARY_PATH=./:$LD_LIBRARY_PATH ./uselib data/coco.names cfg/yolov3.cfg yolov3.weights test.mp4
and got
bash: ./uselib: no such file or directory
Help me solve this please!

Download the latest version of Darknet at the new directory.
Set LIBSO=1 in the Makefile
Do these commands:

make clean
make

I do not know how or why, but after several attempts to do
LD_LIBRARY_PATH=./:$LD_LIBRARY_PATH ./uselib data/coco.names cfg/yolov3.cfg yolov3.weights test.mp4
with responce
bash: ./uselib: no such file or directory
I got libdarknet.so at my root dir. But now new error is occured

Traceback (most recent call last):
  File "darknet.py", line 128, in <module>

    func = self._FuncPtr((name_or_ordinal, self))
