nohup process shown in ps but not in top

Question

I ran a python script say script.py as follows:

nohup python3 script.py &

Now, a process ID is given to me, and the following message comes:

$  nohup: ignoring input and appending output to 'nohup.out'

Now I tried to see top, which shows python3 for some time, and then it is not shown anymore. Using the ps command eventually showed the process. So, I used the process ID to kill it, (which I thought could overcome hanging). Then again I used the nohup command. But again the same things happen.

This may be happening because I'm failing to overcome nohup hanging. This means that I had run this command earlier, and now I need to re-align the streams of nohup. (See this)

My question here is, what should I do now? nohup is still hanged, and I am not able to run commands in the background. Any help is appreciated.

I think this problem created because you used & operator. & gone command to the background and set it as an idle command.

Sorry but I don't understand what you're asking me to do. Can you give me some commands (with formatting if possible!)? – Mooncrater Nov 02 '18 at 08:59
use the command without &: For example: nohup python3 script.py – Hossein.Kiani Nov 03 '18 at 13:20
