can't successfully run STEP 4-A. Cloning and compiling Darknet

[qzhou306]

I've tried numerous times to compile Darknet. It can clone but never is able to fully compiled. I saw darknet files created under content but could never copy it over the google drive. "cp: cannot stat './darknet': No such file or directory"

I would really appreciate anybody's help on this! Qifang
