Couldn't open file

[VincentDuf]

Hi,
I'm currently trying to train a yolov3-tiny network, but I have recurrent errors.
Each time I launch the command it tells me this:
couldn't open file: data/aphids/black_r_labels(number).txt

First, all my image and their text file associated are existing in the "aphids" directory (i used the Yolo_mark GUI) and all the image are listed in the "train.txt" file.
Second it looks after "black_r_labels(46).txt" for example and several other, and when I retry it is other file (so 145 , 32, 78) for instance, I don't know why.
Finally it looks after "black_r_labels()" despite the name of my files being "black_r_images()"...

Can anyone tell me what's wrong ?

Thank you

@VincentDuf Hi,

Do you use this repository or orginal one? In this repository it can't do such changes, a changes replace-function:

darknet/src/utils.c

Lines 208 to 229 in 3d2d0a7

	void replace_image_to_label(char *input_path, char *output_path) {
	//find_replace(input_path, "/images/", "/labels/", output_path); // COCO
	find_replace(input_path, "/images/train2014/", "/labels/train2014/", output_path); // COCO
	find_replace(output_path, "/images/val2014/", "/labels/val2014/", output_path); // COCO
	find_replace(output_path, "/JPEGImages/", "/labels/", output_path); // PascalVOC
	//find_replace(output_path, "/VOC2007/JPEGImages/", "/VOC2007/labels/", output_path); // PascalVOC
	//find_replace(output_path, "/VOC2012/JPEGImages/", "/VOC2012/labels/", output_path); // PascalVOC
	//find_replace(output_path, "/raw/", "/labels/", output_path);
	// replace only ext of files
	find_replace_extension(output_path, ".jpg", ".txt", output_path);
	find_replace_extension(output_path, ".JPG", ".txt", output_path); // error
	find_replace_extension(output_path, ".jpeg", ".txt", output_path);
	find_replace_extension(output_path, ".JPEG", ".txt", output_path);
	find_replace_extension(output_path, ".png", ".txt", output_path);
	find_replace_extension(output_path, ".PNG", ".txt", output_path);
	find_replace_extension(output_path, ".bmp", ".txt", output_path);
	find_replace_extension(output_path, ".BMP", ".txt", output_path);
	find_replace_extension(output_path, ".ppm", ".txt", output_path);
	find_replace_extension(output_path, ".PPM", ".txt", output_path);
	}

In the original repo there is this funny issue: pjreddie#842

Try to use the latest version of this repository.

Okay thanks for answering, I think I might have this problem as it replaces all "image" string in "labels".

Where can I find the latest version ? I downloaded just 2 days ago I supposed it is the latest one right ?

Otherwise I will change the name of my image to avoid this issue.

Did you download this repository https://github.com/AlexeyAB/darknet 2 days ago?

Try to download this: https://github.com/AlexeyAB/darknet/archive/master.zip

Aaah I forgot to say but I installed darknet using JK Jung's blog (https://jkjung-avt.github.io/yolov3/) but it is still based on the darknet original repository as he used this "git clone https://github.com/pjreddie/darknet yolov3".

I compared the utils.c in my repository and the one you gave me and here is the difference:
the 2 function "find_replace_extension" and "replace_image_to_label" don't exist in my utils.c.
So should I add them manually (and in the header file) or is it a bad idea because there are connection with other file ?
