I see that the latest update will work for Pascal annotation. But unfortunately, it will not work for my annotation
because in my annotation in <filename> the extension of the file is not there
Here is a screenshot for my annotation

Good Luck

Dear @EngShaheen you are using an old version of this repo, please update and tell me if it works or not. If the problem is still there, please give me exact steps to reproduce the problem, including dataset & annotation you are using.

[EngShaheen]

Thanks for your reply
I've just cloned a new version of this repo and tried again but I got another error

I am using two classes
infected good
I think I have parsed them successfully

also, I think I have initialized weights successfully

[thtrieu]

I suspect you are using --savepb and --train options at the same time? If so, please finish training first before using --savepb (in combination with --load option). --savepb will disable every variable inside the network and turn them into constants, in order to produce a constant protobuf graph, so the net will not have any variable to be optimized (as in error statement).

Best of luck :)

[EngShaheen]

That's right , I was setting the flag of --savepd to be True
now, I set it to False
but I got another error

I really appreciate your effort

[thtrieu]

Well this time I cant really say the fault is on my side. I believe the image the program is trying to read does not exist. Try printing out imPath before doing anything in yolo/drawer.py/yolo_preprocess() and make sure that path does pointing to an image.

[EngShaheen]

I printed the image path and it's correct except that the extension of the image is written in small letters .jpg, and all the extensions of the images in my dataset are in capital letters .JPG
here is a picture for the imPath

here is a picture for the extension of my dataset

is it case sensitive ? is there an easy way to change the parsing somehow, instead of doing it the hard way and renaming all my +1000 images in the dataset?

[thtrieu]

well, I didn't know cv2 imread is case insensitive, I updated the code, please try again

[EngShaheen]

thank you very much for you help
I suppose it is working now 👍

but you should add
import os
at the beginning of the yolo/drawer.py file

also, I suggest that you mention in the readme file that the annotation of the data should be the same format of the PASCAL data (xml file)
and there is a tool to annotate the data is called labelimg that output the same format

and also, I suggest that you make a default folder inside the repo for the innotation, training data and testing data

Have a nice day

[thtrieu]

cool ! thanks for your suggestions, lots of work to be done :)

[thtrieu]

@EngShaheen By the way, I think I figured a better way to do it than patching the error directly inside drawer.py. To avoid future errors, you may want to save the current state of training, pull the new code and re- clean.py and train again (with option --load [number of latest checkpoint]). Good luck.
