pythran export dict以元组为关键 [英] pythran export dict with tuples as key

问题描述

我尝试在需要int数组的函数中使用pythran，对于第二个arg，使用int的元组作为键，并将int作为值：

I try to use pythran in a function that need an int array and for the second arg a dict with tuples of int as keys and an int as value:

myarray = np.array([[0, 0], [0, 1], [1, 1],
                    [1, 2], [2, 2], [1, 3]])

dict_with_tuples_key = {(0, 1): 1, (3, 7): 1}

有关dict的详细信息，请参阅 pythran 的正确方法：

What is the correct way to inform pythran about the dict ?:

#pythran export update_dict((int, int):int dict, int[][])
def update_dict(dict_with_tuples_key, myarray):
    # do something with dict_with_tuples_key and myarray
    # return and updated dict_with_tuples_key
    return dict_with_tuples_key

With （int ，int）：int dict 我收到这个错误：

With (int, int):int dict I get this error:

File "/usr/lib/python2.7/inspect.py", line 526, in findsource
  file = getfile(object)
File "/usr/lib/python2.7/inspect.py", line 403, in getfile
  raise TypeError('{!r} is a built-in module'.format(object))
TypeError: <module 'sys' (built-in)> is a built-in module

推荐答案

从你的回溯，它似乎您正在导入 sys 。在这种情况下，pythran尝试获取导入模块的源来编译它。由于 sys 是一个内置模块，它失败。

From your backtrace, it seems you're importing sys. In that kind of situation, pythran tries to get the source of the import module to compile it. As sys is a built-in module, it fails.
