在Cent OS中复现已发表文章的 神经网络训练过程，报错ValueError: low >= high

Question

Traceback (most recent call last):
  File "trainIEEE39LoadSheddingAgent.py", line 139, in <module>
    env.reset()
  File "/root/RLGC/src/py/PowerDynSimEnvDef_v3.py", line 251, in reset
    fault_bus_idx = np.random.randint(0, total_fault_buses)# an integer, in the range of [0, total_bus_num-1]
  File "mtrand.pyx", line 630, in numpy.random.mtrand.RandomState.randint
  File "bounded_integers.pyx", line 1228, in numpy.random.bounded_integers._rand_int64
ValueError: low >= high

报错如上，为什么会这样报错？如何解决？谢谢！

Answer 1

np.random.randint(low,high)中，出现这种错误即你的total_fault_buses取值为0，你的low=high=0就会报错了！
