Creating new notebook in /Documents/EK EsawiPD/ScriptsĠ9:21:25.228 ServerApp] Failed to run command: Kernel json file, but I don’t know how to change them to run the kernels Python3 c:\users\eesawi\appdata\local\programs\python\python39\share\jupyter\kernels\python3 Julia-1.7 C:\Users\eesawi\AppData\Roaming\jupyter\kernels\julia-1.7 Ir C:\Users\eesawi\AppData\Roaming\jupyter\kernels\ir Whole page of messages because it may not be appropriate to do so. Hand, generates messages but I don’t understand them and don’t want to post the It just simply will not run the code and suddenly, instead of the active kernel Note that the directories for where the `kernel.json` files reside can be found using `jupyter kernelspec list` and (for completeness) the left-hand values of that output is the string that should be referenced in the 'default_kernel_name' configuration option. Note that I'm not familiar with the Julia kernel or its default naming but am assuming its configuration resides in the directory named 'julia' - which is the target of the 'default_kernel_name' attribute I reference and where its aforementioned `kernel.json` file will reside. This can be done within a configuration file via 'c.fault_kernel_name=julia' or the command line via 'fault_kernel_name=julia'. Lastly, if you would like to change your "default" kernel, you can configure 'fault_kernel_name=julia'. You will likely need to look at the `argv` stanza of the `kernel.json` file associated with your R and/or Julia kernels since that is the command that is issued to start each kernel. You probably have some additional dependencies missing. I recommend looking at your server's console (where the Lab instance was started) since there should be some information specific to the failed start attempts. I suspect your R and Julia kernels are not correctly configured since it appears the server knows about them (as they are selectable) but is encountering an error during their startup. Had the project been named Jupyter from the start, I imagine the extension would have been ".jnb". The ".ipynb" extension is not meant to indicate the type of kernel to which the notebook file is associated, it's purely an indicator that this is a Jupyter notebook and is more a function of the project having been originally named IPython.
