Before conda install nb_conda_kernels in 'base' env,
jupyter kernelspec list outputs as normal,

Available kernels:
python3 User/.../kernels/python3

After conda install nb_conda_kernels in 'base' env,
jupyter kernelspec list outputs with a WARNING,

[ListKernelSpecs] WARNING | Config option kernel_spec_manager_class not recognized by ListKernelSpecs.
Available kernels:
python3 /Users/.../kernels/python3

Also replicated in another environment (created by duplicating 'base' env before installation of nb_conda_kernels).

Don't worry about that. This comes from the current lack of generic dynamic loading mechanism for custom kernel spec provider.

Cool, thanks.

@fcollonval When this warning can be fixed to remove? Still have such warning while executing the same command, and more when installing packages:
