Description

[C 15:34:44.969 NotebookApp] Bad config encountered during initialization:
[C 15:34:44.969 NotebookApp] The 'kernel_spec_class' trait of instance must be a type, but 'beakerx.kernel_spec.BeakerXKernelSpec' could not be imported

This is the error I get when I try to start jupyter notebook from command. I have no clue what is wrong. Anything would be helpful. Thanks!

Research direction

The report names no source files or tests. Start by reproducing the failure with the `jupyter notebook` command and inspect how the `kernel_spec_class` configuration attempts to import `beakerx.kernel_spec.BeakerXKernelSpec`. Done means determining whether the import failure is caused by Notebook or external BeakerX configuration and documenting or fixing the confirmed cause.
