mAP cannot be determined for yolov4

[anusha657]

Hi , I want to determine mAP value ( using pre-trained weights and config file) for an image as well as for a video and below is the command I am using to do that .

!./darknet detector map cfg/coco.data cfg/yolov4.cfg /content/drive/My\ Drive/Colab\ Notebooks/yolov4.weights

However it throws out an error "Couldn't open file: data/train.txt" .Here I am NOT doing training .

PFA (coco.data) file
