2 years ago @khoroshyy I had the same issue yesterday. For me it was a problem of CadQuery dependencies. I had to install nptyping=1.4.4. The nptyping project had released 2.0.0
Maybe it is the same problem for you?

I try to connect from raspbery pi to a remote cadquery jupyter lab running on ubuntu 20.04. But I get the following error. Not sure what is wrong. Is there any way to test cadquery on remote machine without X forwarding? Thanks. Petro.
