It works in jupyter notebook but fails in jupyter lab

Do you have the ploomber plugin installed and the machine restarted? Was it running on different notebooks? We saw in the past users forgot to reset the instance after installation and that caused the plugin some issues.

what Ido mentioned is pretty common. to add more detail: ploomber must be installed in the process that runs jupyter (which isn't necessarily the same process that runs the kernel). although there seems so be some incompatibility here. do you know which version of ploomber and jupyter you're running?
