[Darknet] Cannot load image "-dont_show" despite patch of images and opencv OK

I'll like to know the explanation about the output error:

105 conv 18 1 x 1 / 1 76 x 76 x 256 -> 76 x 76 x 18 0.053 BFLOPs 106 yolo Loading weights from backup/obj_100.weights...Done! Cannot load image "-dont_show" free(): invalid pointer when a try to use the ./darknet detector test obj.data obj.cfg backup/obj_100.weights -dont_show -ext_output < data/train.txt > result.txt command. I check the train.txt and the image path is OK: /home/fitlab1/Área de Trabalho/CNN4antsYOLO/darknet/sample_107.jpg The opencv is OK too: python3 -c "\ import cv2 print(cv2.__version__)" 4.2.0

and the prediction direct with the file image name using the command ./darknet detector train obj.data cfg/obj.cfg darknet53.conv.74 -map | tee log.txt work very well:

105 conv 18 1 x 1 / 1 76 x 76 x 256 -> 76 x 76 x 18 0.053 BFLOPs 106 yolo Loading weights from darknet53.conv.74...obj Done!

Is there some explanation for this error?
