Darkflow: Cannot load weight anymore

Created on 21 May 2017 · 14Comments · Source: thtrieu/darkflow

After pulling new version, I couldnt load the weight anymore.
I got the following error.
"

This error didn't happen in the old version, which is ee6fd2c.

@hungnguyen0606 Just trying to narrow down the problem - the yolo.cfg file was recently updated in darkflow to match the current yolo.cfg and yolo.weights available from the darknet repo and pjreddie.com.

Can you try re-downloading the yolo.weights (assuming that's the weight file you are using) from here: https://pjreddie.com/media/files/yolo.weights and see if that does anything?

@abagshaw
Thank you!
According to the size of your weight file, it makes some sense now. :D
I will try it.

New .weights file updated in google drive.

I'm having this issue with yolo-tiny-voc.weights. I modify classes to 1 and filters to 30 and get.

Also have the problem with yolo-tiny.cfg/weights

I have the same error. I use yolov2-tiny.weights with yolov2-tiny.cfg, both downloaded from https://pjreddie.com/darknet/yolo/. Is it a proper way to do things or should I use darkflow copy of cfg file? Why cfg files are included in this repo and not downloaded from yolo site?

jembezmamy on 10 Jun 2018

@jembezmamy use a different name for 'yolov2-tiny.weights' as the _same name for .weights and .cfg file not working_ when using custom datasets.
In my case, just by changing the name for tiny-yolo-voc-4c.weights to yolo-tiny-voc-4c.weights and keeping the yolo-voc-4c.cfg file name unchanged, made the model go for training.

Did you solve it? I am having the same problem.

You should use the same name for *.weights and *.cfg . I solved this in my case.

I get the same assertion error.. tried changing the cfg and weight files' names and all that. Please provide your insights.
