Hi, I’m having troubles selecting a Kernel in Jupyter Lab.

Here is the output of “jupyter kernelspec list”:

> [ListKernelSpecs] WARNING | Kernel ‘Python 3’ is referencing a kernel provisioner (‘local-provisioner’) that is not available. Ensure the appropriate package has been installed and retry.  
> [ListKernelSpecs] WARNING | Kernel ‘Python 2’ is referencing a kernel provisioner (‘local-provisioner’) that is not available. Ensure the appropriate package has been installed and retry.  
> [ListKernelSpecs] WARNING | Kernel ‘local-venv’ is referencing a kernel provisioner (‘local-provisioner’) that is not available. Ensure the appropriate package has been installed and retry.  
> [ListKernelSpecs] WARNING | Kernel ‘myenv’ is referencing a kernel provisioner (‘local-provisioner’) that is not available. Ensure the appropriate package has been installed and retry.  
> [ListKernelSpecs] WARNING | Kernel ‘R’ is referencing a kernel provisioner (‘local-provisioner’) that is not available. Ensure the appropriate package has been installed and retry.

Any idea what’s wrong? I’m also using Hydrogen for Atom. There the kernels are working. Could Hydrogen be interfering with Jupyter?
