OpenMDAO SimpleGADriver并行运行

Question

有些人成功地在启用了运行并行mod的情况下运行了OpenMDAO SimpleGADriver吗？

当我试图从官方网站(算法.#并行运行-a-ga-)运行他们的示例时，每次都会失败，并返回以下错误：

Traceback (most recent call last):
  File "C:\Program Files\Python39\lib\code.py", line 90, in runcode
    exec(code, self.locals)
  File "<input>", line 24, in <module>

    x_pop = comm.bcast(x_pop, root=0)
AttributeError: 'FakeComm' object has no attribute 'bcast'

曾经有人面对并解决过这个问题吗？

事先非常感谢

看起来，它使用的不是使用适当的MPI安装的脚本，而是使用FakeComm，如果没有安装mpi4py，这是一个虚拟类。您应该能够安装mpi4py，然后并行运行该示例。
