@fuwei199006 Thanks for the feedback. Could you also point out which method call on java raised the exception?

[bigfish1913]

When Java calls Python and imports numpy library . This doesn't seem to be the problem with this component。

#coding=utf-8
import numpy as np
print(1+2)
print("==============")
x = np.array(range(0, 50))
print(x)

Call in Java to try this

Sorry for replying so late. I have finally tried to test on Mac with Apple Silicon. But if numpy is correctly installed with python 3.9, I haven't seen that error. With another Python version, I also struggled to install the library, so please check if numpy is correctly installed first. ref: https://stackoverflow.com/questions/71745890/incompatible-architecture-have-arm64-need-x86-64-error-while-installing
