Sfepy:在python3.7windows上找不到模块

Question

我试着在ipython上用solve\u pde运行its2D\u 2.py，但没有发现模块错误。脚本下的子文件夹一切都在那里，但我不能搞清楚

----> 1 pb, state = solve_pde('its2D_2.py')

~\Anaconda3\lib\site-packages\sfepy\applications\pde_solver_app.py in solve_pde(conf, options, status, **app_options)
     30     if not isinstance(conf, ProblemConf):
     31         required, other = get_standard_keywords()
---> 32         conf = ProblemConf.from_file(conf, required, other)
     33
     34     opts = conf.options = (dict_to_struct(app_options, flag=(1,),

~\Anaconda3\lib\site-packages\sfepy\base\conf.py in from_file(filename, required, other, verbose, define_args, override, setup)
    344         that should be defined using the `define_args` tuple or dictionary.
    345         """
--> 346         funmod = import_file(filename, package_name=False)
    347
    348         if "define" in funmod.__dict__:

~\Anaconda3\lib\site-packages\sfepy\base\base.py in import_file(filename, package_name, can_reload)
    177
    178     else:
--> 179         mod = __import__(name)
    180
    181     if (name in sys.modules) and can_reload:

ModuleNotFoundError: No module named 'its2D_2'

看起来它的2d_2.py脚本有问题或者无法加载它。但每个文件夹和文件都在目录中。任何帮助都将不胜感激 its2.py脚本
