I have created program to follow human and while uploading sketches it showing below error.

option enabled in File -> Preferences.
I am not able to upload the sketch to the device because of mentioned error

I asked, because the more verbose report will likely identify that you have a fundamental communication issue, and it really doesn't matter if your code is perfect.
Do you have the correct COM port selected in the IDE? Can you load and run the simple blink.ino code? If not, don't fuss with your code, find the more pressing issue.
If your IDE tries 10x to upload and fails(this should be evident in the status information after the upload process), it's usually COM related. Does your PC even acknowledge when you plug in the Arduino? If so, you can open Device Manager and observe which USB COM port appears and disappears.
Ok. This is, I think, either a wrong driver (Is your UNO genuine, or a knockoff?), or a bootloader issue. I don't have UNOs, so perhaps someone else can step in here?
