I keep getting this error 'notebook' is not a Jupyter command when trying to make a launcher (in Linux Mint mate panel) for jupyter notebook. The command I put in the launcher is /home/fehiepsi/miniconda3/bin/jupyter notebook. If I replace jupyter by ipython, then things go well. So I guess that the command jupyter notebook is different to ipython notebook, isn't it?

I install ipython notebook by using conda and just install jupyter today (of course, I have updated all packages). Could anyone please give me some suggestions?

Additional informaltion: I just run jupyter notebook well in the terminal, so the problem might lie on the launcher. But I get confused because in the launcher, the command ipython notebook runs well.
