test_tensor = [[2], [1, 2, 3], [4, 5]] # irregular shape # dose there have tf (better, , faster?) function pad tensor dense tensor defult value? # this: test_tensor ==> dense tensor:[[2, -1, -1],[1, 2, 3], [4, 5, -1]]

ps. please not use pure python & numpy

(side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
