ImportError: numpy.core.multiarray failed to import in Jetson environment

I encountered an ImportError when running the demo script on my Jetson environment. The error message is as follows:

You need to clone the GraspNMS GitHub repository (https://github.com/GouMinghao/graspnms), then modify the grasp_nms.pyx file by adding np._import_array() after cimport numpy as np.

I tried. But I meet new erro, like "ValueError: numpy.ndarray size changed, may indicate binary incompatibility. Expected 96 from C header, got 88 from PyObject". Need I change other documents? Sorry for this more question.
