由于难以编译扩展类型，正如“未赢编译”所述。在下面的链接中，有人认为AssertionError与扩展类型有关（在它们的实例化转移到主pyx文件之后）。
来自此forum post的人说“如果你真的想要扩展类型，并且想在你的代码中声明它们的类型，你需要在.pxd文件中声明它们的C属性。”
如果在这种情况下确实如此，问题是当使用pxd文件时pyx文件won’t compile对我来说。在一个pyx文件中编译扩展类型时没有错误，但是在导入后使用扩展类型时我收到错误extTypeName is not a type identifier。
我在comments告诉我，扩展类型可以在pyx文件中定义，主函数使用它们。这样做时，我收到一个错误，我不知道如何跟踪（AssertionError: unexpected type int and base type tuple object for indexing）。完整的追溯发布在下面。
尝试使用在同一个pyx文件中声明的扩展类型进行编译时的回溯（我不确定是问题的根源）：

AssertionError: unexpected type int and base type tuple object for indexing
答案 0 :(得分：2)
回复我可以从您的信息中获取的内容。
cdef某些部分就会受到限制。尝试通过＆＃34; un＆＃34; -cdefing the dict。x[y]，其中x为元组，y为int。原则上它应该可以正常工作（使用int索引一个元组就可以了）。因此，您可以查看Cython中的方括号以找出它的来源。答案 1 :(得分：0)
扩展类型在编译时不是问题（至少在与主cdef函数相同的pyx文件中声明时）;错误正在其他地方出现。
<强>解决：
将元组声明为：
cdef:
tuple curIRs
...并在嵌套循环中设置为：
for deriv1 in xrange(len(L1)):
for deriv2 in xrange(len(L2)):
curIRs = (deriv2, deriv1)
...访问元组索引：
d1[ix] = (curIRs[0], curIRs[1])
这显然是一种无害的疏忽，curIRs不只是存储而不是通过索引访问实质上复制它。但是，这是错误发生的原因：
当用curirs替换（curIRs [0]，curIRs [1]）时，AssertionError停止。
Pierre de Buyl在评论中提出的建议非常有用：'删除潜在问题变量的cdef声明，直到错误得到解决。即，在Python中可能没有错误的地方，可能会在Cython中发现不兼容性
