Still problems loading probes from library

[vincisLab]

Hello,

we are still experiencing issues when trying to load probes from library. For example

`import probeinterface as pi from probeinterface import plotting

probe = pi.get_probe(manufacturer='neuronexus', probe_name='A1x32-Poly3-10mm-50-177') `

will give

This happens also if we try to load Cabridge neurotech probes.

Thanks for the help!

@vincisLab sorry to get back to this so late! Any update?? Were you able to doenload the probe from the library?

[vincisLab]

Hi @alejoe91, yes now everything is working properly.

[alejoe91]

Closing then!

Hi all, I am having the same issue with macos. I am also trying to import Cambridge Neurotech probes (ASSY-77-P-2).

Version for probe interface is: 0.2.17
