Currently, I am recieving the error: cdef np.ndarray[np.int64_t, ndim=1] time = np.empty([1], dtype=np.int64) ^ ------------------------------------------------------------ data.pyx:22:40:

问题 In linux environment, when I run the setup script for cython, I get gcc -pthread -B /apps/.../compiler_compat -Wl,-sysroot=/ -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -fPIC -I/ap...... for my case, I want to remove the pthread option. How do I do that thru the cython setup file? I see there are options to add compiler flags but none to remove. My setup file: from distutils.core import setup from Cython.Build import cythonize from distutils.extension import Extension

Details I am building two packages involving cython, a package A and a package B that depends on A . A is a subpacke of a namespace package nsp . That is, the folder structure looks as follows: ├── nsp │ └── A | ├── extension.pxd | ├──
