Questions about simple_spread agent actions

[zhouweiqing-star]

Hello ，dear author, I saw someone on github reproduced maddpg in the mpe environment, the joint action generated each time in him is [array([1.3097883e-02, 9.7529411e-01, 4.0262565e-03, 6.8232100e -03, 7.5863604e-04], dtype = float32), array ([0.11447875, 0.01806207, 0.00564417, 0.04932265, 0.8124923], dtype = float32), array ([0.23820595, 0.5213099, 0.12905039, 0.07524598, 0.03618779], dtype = float32 )], why does the action of an agent correspond to array([1.3097883e-02, 9.7529411e-01, 4.0262565e-03, 6.8232100e-03, 7.5863604e-04], which contains 5 values, what do they mean? ?
