# Hi, I am getting this launch error every time I am trying to open Jupyter Notebook through anaconda. I even tried to reinstall anaconda which didn’t help. Can someone help here in this community?

You’ll see [here](https://discourse.jupyter.org/t/issue-in-jupyter-notebook/21576/2) that error (`No module named 'jupyter_server.contents'`) is posted as an issue and has suggestions for fixing it. (There’s also [here](https://stackoverflow.com/q/77402235/8508004) and [here](https://stackoverflow.com/q/77420140/8508004) that probably would come up when you are searching that first `ModuleNotFoundError` error that comes up. You may want to peruse the contents, especially in light of my next paragraph.)

Related: The first occurrences of lines starting ‘File’ in that traceback indicate you’ve mixed and matched and made things complex on your system. The first one links to the Anaconda distribution as the source and the next two are independent of Anaconda. Mixing-and-matching like that can make things harder going forward.
