importterror当从PyJulia调用Julia模块函数时

Question

我试图在一些Python代码中包含Julia函数(PowerModelsDistribution.solve_mc_opf)。这个包在Julia中工作，但我被困在PyJulia中。我尝试了一些方法:

1。

from julia import Pkg
Pkg.activate("C:/Users/Aisling/.julia/environments/pmd") # pmd is my Julia env but I've also tried this in my base
from julia.PowerModelsDistribution import solve_mc_opf

在

搜索结果

ImportError                               Traceback (most recent call last)
<ipython-input-33-6e83bbbb609c> in <module>
----> 1 from julia.PowerModelsDistribution import solve_mc_opf
C:ProgramDataAnaconda3libsite-packagesjuliacore.py in load_module(self, fullname)
258                                               JuliaModule(self, fullname))
259 
--> 260         raise ImportError("{} not found".format(juliapath))
261 
262 
ImportError: PowerModelsDistribution.solve_mc_opf not found

1. 然后我试着:

import julia
jl = julia.Julia()
res = jl.run(PowerModelsDistribution.solve_mc_opf("documents/powermodelsdistribution/test/data/opendss/case3_unbalanced.dss", ACPUPowerModel, Ipopt.Optimizer))

结果:

---------------------------------------------------------------------------

----> 1 res = jl.run(PowerModelsDistribution.solve_mc_opf("documents/powermodelsdistribution/test/data/opendss/case3_unbalanced.dss", ACPUPowerModel, Ipopt.Optimizer))

174     def __getattr__(self, name):
175         try:
--> 176             return self.__try_getattr(name)
177         except AttributeError:
178             if name.endswith("_b"):
C:ProgramDataAnaconda3libsite-packagesjuliacore.py in __try_getattr(self, name)
197             return self._julia.eval(jl_fullname)
198 
--> 199         raise AttributeError(name)
200 
201 
AttributeError: solve_mc_opf

我难住了。

Answer 1

我想你应该这样做:

from julia import PowerModelsDistribution
PowerModelsDistribution.solve_mc_opf("...")

所以你应该导入一个Julia模块到Python而不是函数。
