HELP ME OUT !!

[AlexeyAB]

Write data/obj.names instead of obj.names in the file obj.data

Create file obj.data in the directory builddarknetx64data, containing (where classes = number of objects):

classes= 2
train  = data/train.txt
valid  = data/test.txt
names = data/obj.names
backup = backup/

Hello,
I have the same problem right now, training went fine, but now if I want to evaluate the map or the test data, it doesn't work. I specified the full directory for obj.names not the relative directory and it doesn't work. Why wouldn't it work for map and work for the training? I also added the line -map in the train command. Any help would be much appreciated!

The training command: ./darknet detector train data/obj.data cfg/yolov3-tiny_obj1.cfg yolov3-tiny.conv.15 -map
The map command: ./darknet detector map data/obj.data cfg/yolov3-tiny_obj1.cfg backup/yolov3-tiny_obj1_5000.weights
The test command: ./darknet detector test data/obj.data cfg/yolov3-tiny_obj1.cfg backup/yolov3-tiny_obj1_5000.weights
The content of obj.data:
classes= 8
train = /home/abanoub/Desktop/train.txt
valid = /home/abanoub/Desktop/train.txt
names = /home/abanoub/Desktop/daknet-master_last/data/obj.names
backup = backup/
Thank you very much for your help and swift response!

Try to do

cd home/abanoub/Desktop/daknet-master_last/data/
sudo apt-get install dos2unix
dos2unix obj.data
dos2unix obj.names

./darknet detector test data/obj.data cfg/yolov3-tiny_obj1.cfg backup/yolov3-tiny_obj1_5000.weights

What error do you get using this command?

@AlexeyAB

./darknet detector test data/obj.data cfg/yolov3-tiny_obj1.cfg backup/yolov3-tiny_obj1_5000.weights What error do you get using this command?
It's the same error
Couldn't open file: /home/abanoub/Desktop/daknet-master_last/data/obj.names
I ran again the test command and it gave me the same error again

@AbanoubMamdouh

• show me the full path to the ./darknet

• Show screenshot of output of these commands:

cat data/obj.data
cat /home/abanoub/Desktop/daknet-master_last/data/obj.names
ls -l /home/abanoub/Desktop/daknet-master_last/data/obj.names

• run this command:
  ./darknet detector test /home/abanoub/Desktop/daknet-master_last/obj.data cfg/yolov3-tiny_obj1.cfg backup/yolov3-tiny_obj1_5000.weights

[AbanoubMamdouh]

@AlexeyAB
The path to ./darknet is:
/home/abanoub/Desktop/darknet-master_last




Could it be something in the permissions?

[AlexeyAB]

@AbanoubMamdouh

Look at this image - there is incorrect path:

you should use data/obj.names instead obj.names

[AbanoubMamdouh]

@AlexeyAB
I just copied the path you wrote, added the path and same error again

[AlexeyAB]

@AbanoubMamdouh May be you should use darknet instead of daknet )

[AbanoubMamdouh]

The power of a letter... Thanks man!
