[edmBernard]

Thanks for the example. I will check for the issue Can you give me the signature of test::forward ? or maybe you test.cpp file

[edmBernard]

It seem to be an issue during the import of numpy and not in the library generated by pybind11. Did you get this erro if you comment

from module import test
image = cv2.imread("frame.bmp")
d = Nm("test.db", 0,-1, 0)
out = d.forward(image)

print(out)

[kotbegemot]

What is required of me ?

[kotbegemot]

method signature :

auto test::forward(cv::Mat input_data) -> py::array_t<float> { }

[edmBernard]

Could you give me the content of test.cpp ? I was not able to reproduce your issue

[edmBernard]

@kotbegemot any news ? have been able to fix the issue ?

[edmBernard]

If you have any update on this issue, feel free to reopen it. thanks
