Running tensorflow for python in multiple cores ?

Hey guys,

Currently working on a tensorflow python script which I plan to use on a server with multiple cores .

The problem is that if I try to run the script in separate ssh sessions it will always default to the same core, and I need it to run in a different core each time so I can take advantage of all of the cores available .

Using tensorflow 2.2 so tf session is no longer available .

Can anyone please tell me how to achieve this ?

Thanks
