/bin/bash: ./darknet: Permission denied

Question

I've created an object detection model using Roboflow's tutorial and have all the saved weights. The one problem I have is deploying it in a Google Colaboratory. I've changed up some code, but it does not seem to work. So in short, model's trained.

How do I use the model in another Google Colaboratory? I've downloaded the whole darknet folder to the environment with a direct download, some plotting functions and then ran:

and then

!./darknet detect cfg/custom-yolov4-detector.cfg backup/custom-yolov4-detector_last.weights {img} #-dont-show

Only to get:

/bin/bash: ./darknet: Permission denied

Any suggestions?

Is darknet executable? Try running `chmod a+x darknet` from the directory containing the file "darknet". Note: this will make the file executable to all users. If you only want the owning user or group to be able to execute the file, supply the relevant arguments to `chmod`. — Alexander Guyer, Aug 08 '20 at 23:21

Just add this before your command: !chmod +x ./darknet

As there is a slight difference with other answer given you need to provide more context to improve its quality. – ZF007 Oct 19 '20 at 14:31

There is a small hack in my case , first run !chmod +x ./darknet . now it will show error but now delete !chmod +x and run as normal again !./darknet – Satish Saini Jun 15 '21 at 03:40

In step 4 of this tutorial you will find the command !chmod +x ./darknet. Depending on your directory, you may need to run !chmod +x ./darknet/darknet. It depends on your folder structure. Worked for me.

need to re-run the darknet !make file

%cd /your_path/
!sed -i 's/OPENCV=0/OPENCV=1/g' Makefile
!sed -i 's/GPU=0/GPU=1/g' Makefile
!sed -i 's/CUDNN=0/CUDNN=1/g' Makefile
!sed -i "s/ARCH= -gencode arch=compute_60,code=sm_60/ARCH= ${ARCH_VALUE}/g" Makefile
!make

you are lacking execution permission for that script, you need to do chmod +x darknet

If your files are already compiled using !make command, then use !chmod +x ./darknet/darknet or else first compile it and then use !chmod +x ./darknet/darknet

If it still doesn't work, delete the entire darknet package and then clone it again.

compile the darknet using the make function

!make

and don't forget to change the makefile

GPU=1
CUDNN=1
OPENCV=1
