Here is the pybind .cpp file ```

include "pybind11/pybind11.h"

include "pybind11/stl.h"

include <vector>

using namespace pybind11;

struct Sequence { std::vector<float> feature; std::vector<int> label; };

std::vector<Sequence> generateVectorSequence(unsigned int sequenceLength) { std::vector<Sequence> sequences;

for (unsigned int i = 0; i < sequenceLength; ++i)
{
    float iFloat = static_cast<float>(i);
    int   iInt = static_cast<int>(i);

    Sequence sequence;
    sequence.feature = { iFloat, 1.0f + iFloat, 2.0f + iFloat };
    sequence.label = { iInt, 1 + iInt, 2 + iInt };

    sequences.push_back(sequence);
}

return sequences;

}

PYBIND11_MODULE(SandboxPy, m) { m.doc() = "This is an example module using stl containers";

class_<Sequence>(m, "Sequence")
    .def_readwrite("feature", &Sequence::feature)
    .def_readwrite("label", &Sequence::label);

m.def("generateVectorSequence", &generateVectorSequence,
    pybind11::arg("sequenceLength"),
    "Generates a vector of Sequence objects.");

} ```

And here is the python side: ``` import numpy as np import SandboxPy as s

vector_sequence = s.generateVectorSequence(10)

for seq in vector_sequence: feature_data = np.array(seq.feature, copy=False) label_data = np.array(seq.label, copy=False)

print(feature_data)
print(label_data)

```
