Cython generally doesn't convert implicitly between arbitrary Python objects and C/C++ types, you have to type your code explicitly. Also, it is [better](https://cython.readthedocs.io/en/latest/src/userguide/special_methods.html#initialisation-methods-cinit-and-init) to use `__cinit__` here so that the constructor never gets skipped, so for example (untested): ```cython def __cinit__(self, int64_t pivot): self.partition_nth_options.reset(new CPartitionNthOptions(pivot)) ``` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
