Darkflow: errors when running sample flow

[skylinetech-team]

hi, I tried the following flow command

./flow --model cfg/tiny-yolo.cfg --load bin/tiny-yolo.weights

appears tiny-yolo.weights not existing from the download place

so I ran again with one of the downloaded weight file:

./flow --model cfg/tiny-yolo.cfg --load bin/yolo-tiny.weights

got the following errors, any suggestions ?

[skylinetech-team]

it seems that the cfg file and weight file expected to be the same name ????

the one I ran before:

cfg/tiny-yolo.cfg --load bin/yolo-tiny.weights

loader somehow expects cfg/yolo-tiny ??

[skylinetech-team]

hi, all these lines below runs ok for everyone ? we are getting errors mentioned above.

seems the cfg file and weights not match, any suggestions ?

1. Load tiny-yolo.weights

flow --model cfg/tiny-yolo.cfg --load bin/tiny-yolo.weights

2. To completely initialize a model, leave the --load option

flow --model cfg/yolo-new.cfg

3. It is useful to reuse the first identical layers of tiny for yolo-new

flow --model cfg/yolo-new.cfg --load bin/tiny-yolo.weights

this will print out which layers are reused, which are initialized

[skylinetech-team]

only yolo.cfg and yolo.weights works

./flow --model ./cfg/yolo.cfg --load ./bin/yolo.weights

[idhamhalim]

use this ./flow --imgdir sample_img --model cfg/tiny-yolo-voc.cfg --load tiny-yolo-voc.weights --threshold 0 --gpu 1.0

Do note that you have to download the tiny-yolo-voc.weights first , though.

I think the problem is your cfg file and weights file DO not match.
Make sure they are a couple.......

[skylinetech-team]

yup, thanks, guys !

this is working

./flow --model ./cfg/tiny-yolo-voc.cfg --load ./bin/tiny-yolo-voc.weights

[skylinetech-team]

where is tiny-yolo.weights ?
as mentioned in 1st test line
flow --model cfg/tiny-yolo.cfg --load bin/tiny-yolo.weights

seems tiny-yolo.weights are not in Git ?

[skylinetech-team]

also where's the cfg/yolo-new.cfg ?

is it cloned from cfg/tiny-yolo.cfg ?

I have the same issue. Darknet website lists two files for YOLO 2 Tiny:
https://pjreddie.com/media/files/yolov2-tiny.weights
and
https://github.com/pjreddie/darknet/blob/master/cfg/yolov2-tiny.cfg

Maybe darkflow doesn't work on v2 files yet? Not sure.

Anyway, I could get something working by:

1. Download yolo-tiny.weights from here:
   https://drive.google.com/drive/folders/0B1tW_VtY7onidEwyQ2FtQVplWEU

2. python3 flow --model cfg/v1/yolo-tiny.cfg --load bin/yolo-tiny.weights --savepb --verbalise (Note the v1 in the cfg path)

This is a project. The name of the weights file also does not match what is written in the README instructions. For example, the author lists: "bin/tiny-yolo.weights" but they are actually "yolo-tiny.weights"

[Sequential-circuits]

I put --verbalise and it still does not save the tag set

This is truly frustrating
