Error in AcquireAndDisplay with Spinnaker Python
Answered
I installed Spinnaker Python 3.1.0.79 on Ubuntu 20.04 (Python version 'Python 3.8.10'). I have Blackfly S BFS-U3-13Y3M. I try to run the example of Python package to acquire images with the camera, but this is the error:

thank you, problem solved! the version of the keyboard is good, I think the problem was the directory in which I installed it.

Hi Silvia,
It could be that wrong version of keyboard was installed before running this example project.
Please double check that required version of matplotlib and keyboard are properly installed following the README instructions part of spinnaker python package.
Otherwise, you could open a support ticket via our contact form at https://flir.custhelp.com/app/ask to work through it together.
Regards,
Ifeanyi
