Arapaho: "libdarknet-spp-shared.so: no such file or directory"

[halt9]

Following compilation instructions of arapaho, I can compile it but I can't get it to work. Here's my Makefile:

COMMON= 
CFLAGS=-Wall -Wfatal-errors 

OPTS=-O0 -g
CFLAGS+=$(OPTS)

COMMON+= -DGPU -I/usr/local/cuda/include/
CFLAGS+= -DGPU
LDFLAGS+= -L/usr/local/cuda/lib64 -lcuda -lcudart -lcublas -lcurand

COMMON+= -DCUDNN 
CFLAGS+= -DCUDNN
LDFLAGS+= -lcudnn

COMMON+= -DOPENCV
CFLAGS+= -DOPENCV
LDFLAGS+= `pkg-config --libs opencv-3.2.0-dev` 
COMMON+= `pkg-config --cflags opencv-3.2.0-dev` 

arapaho: clean
    g++ test.cpp arapaho.cpp  $(COMMON) $(CFLAGS) -I../src/ -L./ $(LDFLAGS) -ldarknet-cpp-shared -L/usr/local/lib -std=c++11 -o arapaho.out

clean:
    rm -rf ./arapaho.out    

The parameters are all copy-pasted from my Makefile for darknet. This compiles fine. Yet when I try to run it I get: ./arapaho.out: error while loading shared libraries: libdarknet-cpp-shared.so: cannot open shared object file: No such file or directory despite the lib file being in the same directory and rwx-enabled.

Perhaps some other dependent lib is not found - can you try

ldd ./libdarknet-cpp-shared.so

[halt9]

I won't have access to the machine until tomorrow, but darknet itself runs fine - shouldn't the library file work as well?

[prabindh]

It should, which is why ldd will help in finding what is going on.

I did an ldd, and also an lddtree (from pax-utils). Here's the ldd:

[prabindh]

Could you please try - from linux cmd line - type below

export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH

before you execute arapaho ?

[halt9]

Same error. My LD_LIBRARY_PATH already includes CUDA's libraries.

Would it help if I attached my .so file so you can inspect it?

libdarknet-cpp-shared.zip

[prabindh]

I think the issue is because, you are linking (in the Makefile) against a version of OpenCV in /usr/local/lib, but somehow loader is picking up from /opt/ros/kinetic/lib/. Is this likely ?

[halt9]

The pkg-config --libs opencv-3.2.0-dev command actually returns files in /opt/ros/kinetic/lib - removing the /usr/local/lib line did not change the end result.

By the way, ldd arapaho.out produced libdarknet-cpp-shared.so => not found

[prabindh]

Did you see any warning messages in the linking process of arapaho.out (libraries not found, ..) ?

[prabindh]

The below indicates a dependent library was not found, though it shows libdarknet-cpp-shared.so,

ldd arapaho.out produced libdarknet-cpp-shared.so => not found

[halt9]

I only get warning: left operand of comma operator has no effect [-Wunused-value] type output from the makefile, no linking related messages.

[prabindh]

I still suspect it is to do with OpenCV. Since I am unable to replicate it, could you try once disabling OPENCV flag in both darknet makefile and the arapaho makefile ? Arapaho test wrapper needs opencv, so you will need to just comment out the opencv calls, to make it to build..

[prabindh]

Will check again in a couple of hours.

[halt9]

Solved it! ran it as LD_LIBRARY_PATH=$LD_LIBRARY_PATH:. ./arapaho.out

But now I get error Warning: Read classes from cfg (80) > maxClasses (2)Could not load the AV file input.mp4 even though I have an input.jpg in the folder

[prabindh]

Pls change the input file name in test. Cpp

Wait, never mind, it very briefly shows a window then closes it. I missed it since it was so fast. Seems like it might be working, but it's hard to tell since the window is immediately closed. Is there a way to output the result to the command line or save to a file? Here's the full output:

edit: I'm running this through SSH, but normal darknet works and I can see the window and boxes.

With some effort, I was able to capture the arapaho window. It's just a black box and it's not even the same size as input.jpg.

[prabindh]

I dont think ut worked right.  If detection step was successful you wud see the log as in arapahoreadme.txt And window stays open. Sent from Yahoo Mail on Android

Is there a way to debug it?

[prabindh]

Did you change the input file name INPUT_AV_FILE to input.jpg in test.cpp (Line 36) ?

[halt9]

Yeah, now I get a window popup with a part of the image, then it goes away fast saying

QXcbConnection: XCB error: 145 (Unknown), sequence: 164, resource id: 0, major code: 139 (Unknown), minor code: 20
cap.read failed/EoF - AV file input.jpg

[prabindh]

Looks like an OpenCV error reading the input.jpg. Something related to video/image plugins in the system ? The original comment said [6] detections were done. Was that another image ?

It very briefly shows the image, but I can't tell if it draws detections on it.

[prabindh]

Please pull master, for an update to the test code. Since the jpg is just one frame, the window shows and exits immediately. You can pull the latest code that waits for the user to close the window instead of just exiting. (https://github.com/prabindh/darknet/commit/463a12d7327c12c980dfb75ac339b8584ecdb71c)

[halt9]

I didn't know you could read a single image with VideoCapture. It works now, and draws boxes. BBut it only seems to draw a box around one object instead of 6 detections.

[prabindh]

Very good, could you post a screenshot ?

It draws just one, the 0th block, per current code. All boxes in a future commit,

[halt9]

[prabindh]

ok thanks ! Looks like you are not using the latest tree, as it adds class label display also.

[halt9]

arapaho is from yesterday, though darknet is not because I have some local modifications based on an older version

[prabindh]

Added support for displaying all detected object boundaries and labels. Please get master, commit https://github.com/prabindh/darknet/commit/0e66eed15ef645cd5fcf438fc626c00e05113cf8

[halt9]

note - this commit seems to change the location it looks for the config/data files? Couldn't open file: data/coco.names is what I get when I run it? Or is it related to my darknet .so file being compiled from different code?

[prabindh]

No, but it does look for the names file you have specified in input.data. Looks like you have specified data/coco.names in there, because that path is relative to the main darknet folder. You can change this to the full path name of the coco.names, or atleast ../data/coco.names, as relative to arapaho folder.

[halt9]

You're right, I fixed that now. But I'm back to the EOF error despite waitKey() being in my test.cpp

Full log would be better to see if any symbols were missing. Nothing has changed in that code however, so if it had linked earlier it should link now.

And it shows this window:

[prabindh]

For a single frame, the log is expected after it displays the frame. The code waits for the ESC key from user, before exiting. But I am not able to see the full window screenshot.

[halt9]

That's the full window I get. It doesn't display the entire image for whatever reason.

[prabindh]

Could you share the JPG please ?

[halt9]

Weird, I changed nothing and it just worked now!

[prabindh]

It might point to a bad build procedure (including in Arapaho), so keep an eye on it. If you keep facing it, let me know. Thx

[halt9]

Unrelated to this issue, but I'm now trying to include arapaho in my own code, and I get:

Does this mean the .so file is not being recognized by my cmake? The file is in my include directory that cmake is getting passed (line 108) in the cmakelists file here attached.

Also, presumably I need to compile this code with CUDA and CUDNN like I do the arapaho test code? Are these errors related to darknet, arapaho or cuda/cudnn? CMakeLists.txt

[prabindh]

• yes, .so file is not being linked
• yes, same options need to be used across darknet and arapaho (and thus any other application using arapaho)

[halt9]

I got it to build. Will run it later today and let you know if I encounter any issues.

my prediction is that since I initialize Arapaho in the constructor then call it in the imageCb method, maybe that's the cause for error.

[prabindh]

It seems the memory allocation failed, is there enough memory in the system ?

[halt9]

Yeah, several gigs of unused memory. That seems to me like an error instead of actually being unable to claim memory.

[prabindh]

I can see one issue - // Subscrive to input video feed and publish output video feed image_sub_ = it_.subscribe("/camera/rgb/image_raw", 1, &ImageConverter::imageCb, this);

This needs to be "after" the class is setup.
