[BUG]: Getting numpy error even though my tensors are marked PyTorch

[s1ddok]

Problem description

Receving this:

lib/python3.11/site-packages/torch/_subclasses/functional_tensor.py:258: UserWarning: Failed to initialize NumPy: No module named 'numpy' (Triggered internally at ../torch/csrc/utils/tensor_numpy.cpp:84.)
  cpu = _conversion_method_template(device=torch.device("cpu"))

on the first call to function, even though my function returns this:

typedef nb::ndarray<nb::pytorch, float> PytorchNDArray;

nb::tuple foo(std::string& filename) {
   // logic
  return nb::make_tuple(
      nb::ndarray<nb::pytorch, float>(temp.data1, { temp.count, 3 }, deleter),
      nb::ndarray<nb::pytorch, float>(temp.data2, { temp.count, 3 }, deleter),
  );
}
