Run Detector Test works on individual images, but cannot load multiple images from txt file

[espenwiik91]

In short This doesn't work (trying to use detector test on multiple images in a folder: !./darknet detector test "/content/gdrive/My Drive/darknet/obj.data" "/content/gdrive/My Drive/darknet/cfg/yolov3.cfg" "/content/gdrive/My Drive/darknet/backup/yolov3_final.weights" -dont_show < "/content/gdrive/My Drive/darknet/test.txt"> "/content/gdrive/My Drive/darknet/result.txt"

Error messege is: Cannot load image /content/gdrive/My Drive/darknet/imgTest/test4.jpg Cannot load image /content/gdrive/My Drive/darknet/imgTest/test3.jpg

This does work (detect on one image, using direct path to said image): !./darknet detector test "/content/gdrive/My Drive/darknet/obj.data" "/content/gdrive/My Drive/darknet/cfg/yolov3.cfg" "/content/gdrive/My Drive/darknet/backup/yolov3_final.weights" -dont_show "/content/gdrive/My Drive/darknet/imgTest/test4.jpg" "/content/gdrive/My Drive/darknet/result.txt"

The test.txt file consist of the same path as given in working detector test i.e.: /content/gdrive/My Drive/darknet/imgTest/test4.jpg No spaces or blank lines in it apart from My Drive.

All help is very much appriciated test.txt file linked: test.txt

Hi espenwiik!

You need to use back slash before space in your paths in test.txt, like this:

/content/gdrive/My\ Drive/darknet/imgTest/test4.jpg

It will work only if you are using my darknet's cloned repo (The one used in the tutorial)

I hope this helps! Good luck! David

Hi and thank you for answering. I have been following this guide and completed training of my model. Unfortunately, I get the same error; Cannot load image /content/gdrive/My\ Drive/darknet/imgTest/test4.jpg Cannot load image /content/gdrive/My\ Drive/darknet/imgTest/test3.jpg

Anything else you can think of? Also, this was not a problem during training, where I used a train.txt file for path to all training imges. Example: /content/gdrive/My Drive/darknet/img/005e4044be890b03.jpg

Hello David, I'm also encountering the same issue. I've metoculously followed all the steps mentioned in your "Tutorial DarknetToColab" Notebook.

Every thing runs smoothly until I attempt to train my custom dataset using the following command:

!./darknet detector train "/content/gdrive/My Drive/darknet/obj.data.txt" "/content/gdrive/My Drive/darknet/cfg/yolov3-tiny_obj.cfg" "/content/gdrive/My Drive/darknet/weights/yolov3-tiny.conv.15" -dont_show

My paths in obj.data look like (train = /content/gdrive/My\ Drive/darknet/train.txt) and Paths in train.txt (/content/gdrive/My\ Drive/darknet/img/CAX_Train1.png -- NO space between \ and Drive

The execution goes well showing conv layer etc and then starts throwing cannot load image (as below) and stops execution. ..... .... Total BFLOPS 5.680 Allocate additional workspace_size = 52.43 MB Loading weights from /content/gdrive/My Drive/darknet/weights/yolov3-tiny.conv.15... seen 64 Done! Learning Rate: 0.001, Momentum: 0.9, Decay: 0.0005 Resizing 608 x 608 Very small path to the image:
Very small path to the image:
Cannot load image /content/gdrive/My\ Drive/darknet/img/CAX_Train100.png Cannot load image /content/gdrive/My\ Drive/darknet/img/CAX_Train10.png

I even changed my files from jpg to png but that didn't help... Any direction on resolving this will be highly appreciated..

Hi mister. I did not have the issue when doing training (only when running detection on multiple images) so maybe I can help. More than likely, this is a pathing problem. I've linked mine below so you can have a look, maybe that will help. As you can see, mine DOES have a space in between "My" and "Drive" and it worked fine for me during training train.txt

[devb2020]

Didn't work. Not sure the root cause of the problem. It still throws the same error

[devb2020]

I finally got it working.... Recreated train.txt and manually included the image file paths (though a weird workaround but it worked) I had earlier created using python and that seems to have done something wrong with the file..

Hi All,

Probably is because the end of line character. I can remember which one is the right one, but it works only using linux or windows style.

Good luck! David

Hi to everyone! When i try to train yolov3 in colab it appears to me this eror: "608 x 608 Create 6 permanent cpu-threads " Any soloutions??
