问使用pybind11，如何为array_t对象设置底层内存的所有权？EN如果你不传递数据指针，numpy会为你分配内存。
定义一个函数,用于在单独的线程中实例化pybind11::array_t: 代码语言:txt 复制 void instantiateArray() { // 在这里进行pybind11::array_t的实例化操作 // 例如: pybind11::array_t<int> arr({3, 3}); auto ptr = arr.mutable_data(); for (int i = 0; i < 9; i++) { ptr[i...
py::array_t<float>是pybind11库中定义的一个模板类,用于表示一个NumPy数组,其元素类型为float。这个类提供了一系列方法和属性,使得C++代码可以方便地访问和操作NumPy数组。 request()方法 request()是py::array_t类的一个方法,用于获取数组的缓冲区信息。这个方法返回一个py::buffer_info对象,该对象包含了访问数...
尝试将pybind11：：array_t从c++返回到python时崩溃问题在于使用py::gil_scoped_release来释放GIL，然后...
pybind11 array_t pybind11数据结构介绍 在数值计算用的最多的结构是array_t<>,可以是array_t,array_t或者array_t,当然用的最多的肯定是array_t了。
hello, I am trying to subscript a pybind11::array_t<scalar_t, pybind11::array::c_style> or pybind11::array_t<scalar_t, pybind11::array::f_style>. I know I can use at() or mutable_at but those imply a check on the bounds. I also know I ca...
Issue description The array_t constructor takes its input shape as unsigned size_t (== npt_uintp), even though the numpy API (e.g. PyArray_NewFromDescr) uses signed ssize_t (== npy_intp) and pybind11 itself uses signed sizes in most plac...
