When git doesn't push at last step(Could not read from remote repository)

• Error : When I tried to push the file into the github, it stoped the last step. 

It doesn't give me any result after 'Total 3 (delta 0), reused 0 (delta 0), pack-reused 0'.

$ git remote add origin https://github.com/mellamonaranja/Data_Augmentation_Tensorflow.git
