Erro:Loading weights from yolov31.weights...Couldn't open file: yolov31.weights

[xiaotongnii]

Rrecently,study object detection,hope to use to arrange Yolov3 on Ubuntu1604 in the virtual machine. However,appear some Erro, make me in troble,hope to give some tips!

Envirnment :PC configure：Core（TM）i5-4200 CPU Running Env: virtual machine14 、Ubuntu1604、 Aim :arrange Yolov3 on Ubuntu1604 in the virtual machine. Time:20181123:17:20

step: 1、git clone https://github.com/pjreddie/darknet 2、cd darknet make 3、wget https://pjreddie.com/media/files/yolov3.weights 4、./darknet detect cfg/yolov3.cfg yolov3.weights data/dog.jpg

The error msg says it can't open yolov31.weights. Do you have this file? The command line shows you're using yolov3.weights. Something's not right here.

Frist,thanks for your rely. In fact, this file(yolov3.weights) exist in the /opt/darknet/cfg

xt001@ubuntu:/opt/darknet/cfg$ ls
yolov3.cfg
yolov3.weights 

[PeterQuinn925]

Yeah, but the error msg you posted says it's looking for yolov31.cfg. That's kind of odd.

yea,I try to take some ways to solve it

[flyingbird93]

I have meet same problem. But its easy to solve. I think you should make same mistake with me,just put yolov3.weights file into /cfg. You should put weights file in /darknet, and you can solve it!

[ottovotto]

same problem here --> solved by putting yolov3.weights in /darknet

[ghost]

Be sure about the path of your weights file, had the same problem and in my case reason was the path to weights.

[Aaayue]

same problem here! I changed the running command to : ./darknet detect cfg/yolov3.cfg cfg/yolov3.weights data/dog.jpg add /cfg in front of yolov3.weights, everything fine!

[saangaa]

Incorrect path can lead to this problem.

actually yolov3.weights must be within folder, in your case it's outside the folder....yeahh i did same mistake too.

Have placed weights in right path but issue persists in windows 10. Please help

Download it from here: https://pjreddie.com/media/files/yolov3.weights Then move it to /darknet

Hi,

I was also facing the same issue. There are two darknet folders which might be causing the confusion. I was placing the images and weights inside /darknet initially and i was getting the error. It should be placed inside darknet/build/darknet/x64/weights.

And it worked for me.

[koushik2001]

@sandheepgopinath This actually worked for me

[chenxy1988]

Download it from here: https://pjreddie.com/media/files/yolov3.weights Then move it to /darknet

Thanks a lot, this is working for me. ;)

[thanishap]

I have face same problem , add the yolov3.weights to ./cfg then run the syntax ./darknet detect cfg/yolov3.cfg cfg/yolov3.weights data/dog.jpg error will be resolved.

good
