I have this error on try your code... In darknet we can Run inference, and get results. You know the reason?

tahaemara · 2019-03-13T22:18:19Z

Did you set the number of anchors to 6?. Tiny yolo uses 6 anchors instead of 9 anchors in case of normal Yolo here

ajaykaarthic · 2019-09-15T11:19:23Z

I have set it to 6 and yet i get the error !, how can i resolve this?

Rakhesh96 · 2019-10-16T06:17:07Z

Though i tried anchor values to be 6 and 9 still it is not working, the same error is being show ...kindly help me out @tahaemara

ADLTU · 2019-12-04T02:02:41Z

Hi, if you are using mac I found that if you use the textEdit.app, it adds a few lines at the top(you can't see them unless you use another editor) that are causing an issue, simply remove them and it will be fine.

gmatesunny · 2020-01-07T18:14:46Z

I have set following in yolov3-tiny.cfg

[yolo]
mask = 3,4,5
anchors = 10,14, 23,27, 37,58, 81,82, 135,169, 344,319
classes=4
num=6
jitter=.3
ignore_thresh = .7
truth_thresh = 1
random=1

[yolo]
mask = 0,1,2
anchors = 10,14, 23,27, 37,58, 81,82, 135,169, 344,319
classes=4
num=6
jitter=.3
ignore_thresh = .7
truth_thresh = 1
random=1

still I get the error:

Traceback (most recent call last):
File "yolo_opencv.py", line 49, in
net = cv2.dnn.readNet(args.weights,args.config)

I have also checked whether any extra line is added. I am on Ubuntu 16.04
Suggest me what shall I do next?

I have the same problem

net = cv2.dnn.readNetFromDarknet(_net_weights_path, _net_cfg_path)
cv2.error: OpenCV(3.4.2) /opt/concourse/worker/volumes/live/9523d527-1b9e-48e0-7ed0-a36adde286f0/volume/opencv-suite_1535558719691/work/modules/dnn/src/darknet/darknet_io.cpp:511: error: (-215:Assertion failed) separator_index < line.size() in function 'ReadDarknetFromCfgFile'

Have any idea?

Please tell me more

ADLTU · 2020-01-07T22:28:03Z

@gmatesunny did you check what I said before, do that if you are using mac

DocGrenas · 2020-01-07T22:39:55Z

HI.
I am using Mac and I have checked your suggestion but i can not see the xtra lines.

I have run my program on Vstudio

Another suggestion ?

gmatesunny · 2020-01-07T22:41:51Z

@ADLTU : I checked and it doesn't have extra lines. I am using vscode as editor.

ADLTU · 2020-01-07T23:28:49Z

Please do this and send a screenshot.

DocGrenas · 2020-01-08T19:40:09Z

Hi.

I am using the yolov3.cfg

ADLTU · 2020-01-09T01:15:52Z

Hi it won’t appear there, I had the same problem open the file in terminal and you’ll see. Hadi

@DocGrenas Facing the exact same problem as this:

net = cv2.dnn.readNetFromDarknet(_net_weights_path, _net_cfg_path)
cv2.error: OpenCV(3.4.2) /opt/concourse/worker/volumes/live/9523d527-1b9e-48e0-7ed0-a36adde286f0/volume/opencv-suite_1535558719691/work/modules/dnn/src/darknet/darknet_io.cpp:511: error: (-215:Assertion failed) separator_index < line.size() in function 'ReadDarknetFromCfgFile'

Have you managed to solve it? Thanks!

MorshedBabu · 2020-04-24T14:04:20Z

Use absolute path, it would work. For example,

For Loading Yolo

net = cv2.dnn.readNetFromDarknet("/home/babu/darknet/cfg/yolov3-tiny.cfg","/home/babu/darknet/yolov3-tiny.weights")

For Loading image

img = cv2.imread("/home/babu/darknet/data/dog.jpg")

I get this

I did this but still getting the same error...

I tried all above steps, but nothing worked, can anyone help me with this... Thank You!

Try using this yolov3.cfg file. You will have to unzip it first.

yolov3.cfg.zip

Even i'm getting same error while performing prediction on trained YOLOv3 Tiny. I i have checked number of anchor are 6 only.

Could someone help me on this please .

I have trained model in my virtual machine Ubuntu 20.04

Command
darknet$ python3 yolo_opencv.py -c /home/ai/darknet/training/yolov3-tiny.cfg -w /home/ai/darknet/backup/yolov3-tiny_60000.weights -cl /home/ai/darknet/training/objects.names

sujitvasanth · 2021-01-24T13:50:26Z

Thannks @fadeos your cfg file worked...for me...
i read the original cfg file downloaded from darknet website and it was a html file.....

fedeos · 2021-01-24T14:10:24Z

Great! I hope you can move on and complete your project.

charlie6echo · 2021-04-07T20:43:06Z

the Original file that is on pjreddie's repo has been corrupted, please refer this one yolov3.cfg.

andyrey · 2021-11-25T19:37:26Z

Just check up your .cfg file carefully. In my case, I accidentally removed # before word Testing. When transfer configuration file from training mode to testing one, we can do very simple error inadvertently.

Vinod95-git · 2021-12-01T11:40:10Z

I get the same error but I am using yolov4 model. Any suggestions please?

trabelsim · 2022-01-02T21:29:32Z

I had the same issue and even trying with the new .cfg file did not work.
Have a look at the order of the argument You are providing!

OpenCv in its documentation states that the order of model and config arguments does not matter, HOWEVER in my case it did matter. First config file and then weights (for DarkNet).

This works for me:
Net net = readNetFromDarknet(modelConf, modelWeig);

smallbook · 2022-01-02T21:46:24Z

I think this is due to a few # in the cfg file that you need to remove,
and try again,
it worked for me.

Soroosh-N · 2022-02-02T05:21:30Z

I think the problem is that some of us are downloading the "PAGE OF FILE". not the file itself! I mean, for downloading the cfg file, don't use this link:
https://github.com/pjreddie/darknet/blob/master/cfg/yolov3.cfg
Instead, use this link (The exact same file. but its file address. not page address):
https://raw.githubusercontent.com/pjreddie/darknet/master/cfg/yolov3.cfg
Hope it works for you.

K-GOKULAPPADURAI · 2022-11-12T04:14:03Z

Try with this yolov3-tiny.cfg file: yolov3-tiny.zip

ya that error gone but a new error came

cv2.error: OpenCV(4.5.5) D:\a\opencv-python\opencv-python\opencv\modules\dnn\src\darknet\darknet_io.cpp:933: error: (-213:The function/feature is not implemented) Transpose the weights (except for convolutional) is not implemented in function 'cv::dnn::darknet::ReadDarknetFromWeightsStream'

Emyyr · 2023-05-07T19:51:14Z

Hi ,

I tried this method and this solved my problem but I want to talk about another solution. Configs are not broken. This is my idea. Just change your anchors from from your .cfg file. I put COCO anchors from yolov3-tiny.cfg to my cfg and it worked for me. You can try this options:

Control your .cfg file (spaces, comments "#" )
Control batch and subdivision (batch=1, subdivisions=1). I am writing this but didn't try :) . Because yolov3-tiny.cfg's batch and subdivison like this.
Control your .cfg and .weight file path in your code.
Control your anchors.

Try with this yolov3-tiny.cfg file: yolov3-tiny.zip
