Cython-从Jupyter Nookbook（魔术％）到python.exe上的.py

Question

我刚刚在jupyter上使用cython编写了一个函数：

%load_ext Cython

%%cython 
def modelar(lista, int leadtime, int recompra, int qtd, int seg, int dsv, int numero=1):
    import math
    import pandas as pd
    import numpy as np

    cdef int data = 0
    cdef int n = 0
    ....

当我尝试以.py脚本下载以便仅使用python运行时，它的转换如下：

get_ipython().run_line_magic('load_ext', 'Cython')

get_ipython().run_cell_magic('cython', '', "def modelar(lista, int leadtime, int recompra, int qtd, int seg, int dsv, int numero=1):\n    import math\n    import pandas as pd\n    import numpy as np\n    \n    cdef int data = 0\n    cdef int n = 0\n    cdef float c = 0\n    cdef float V = 0\n")

但是，它没有运行。看起来像这样的错误：

AttributeError: 'NoneType' object has no attribute 'magic'
