Hi, I am desparately trying to run the Zed 2i . I have the following installed:

Cuda 11.1  
Python 3.7.4  
ZED SDK 3.5

I continue to get the following error

```
import pyzed.sl as sl

```

File “pyzed\sl.pyx”, line 1, in init pyzed.sl  
ValueError: numpy.ndarray size changed, may indicate binary incompatibility. Expected 88 from C header, got 80 from PyObject

It was available until I modified the version of numpy and scipy. The current version of numpy is 1.16.5， scipy is1.5.2

Can you please clearly explain how to fix this issue?

Hi @Lanlan  
can you please provide more information about the operating system that you are using and the Python environment?  
Furthermore, you are using a quite old ZED SDK, I suggest you update to the latest SDK v3.7.2 and you also update the Python wrapper.
