Hi  
I’m experimenting with the vilib examples from here:

> **[vilib/examples at picamera2 · sunfounder/vilib](https://github.com/sunfounder/vilib/tree/picamera2/examples)**
>
> Vision library for python. Contribute to sunfounder/vilib development by creating an account on GitHub.

on my pidog. Specifically, object\_detection.py

However, it will not run (the other examples run fine) I get the following error

ERROR: type object ‘Vilib’ has no attribute ‘object\_detection\_list\_parameter’

Has the API changed between the above github release, and the pidog one?  
Thanks

To help us analyze and resolve the issue you’re experiencing, could you please provide a complete screenshot of the error message?

In the meantime, please try the following commands to update your code:

cd ~/vilib  
git pull  
sudo python3 install.py

Once the installation is successful, restart your Raspberry Pi and run the example again to see if it works.

Thanks. There appears to have been a patch in the picamera2 branch, 2 weeks ago which addresses this, I quote

'Fix bug of ‘Vilib’ has no attribute"

I was using an old master branch., which was probably my problem

Yes. The appropriate method is to use the Vilib library from the picamera2 branch.
