After recently installing Anaconda, I’m having issues with Jupyter Notebook. When I create an .ipynb file, it’s not clickable and won’t open. I’ve tried reinstalling Jupyter Notebook, but it hasn’t resolved the problem. How can I fix this?

Is this a fresh installation? Specifically when you say, “After recently installing Anaconda” do you mean it has never had Anaconda/conda on it or Jupyter? Or were you uninstalling and then reinstalling things? I ask because often with the radically different infrastructure of more current Jupyter Notebook and Jupyter Server, if old things are left around they can interfere.

If you aren’t that invested in Anaconda and you just want to get past this hurdle, I will add that JupyterLab Dekstop should be the easiest way to install Jupyter these days. See here and make sure it read through the post how to use it as the project management model it assumes may be different than other ones with which you are familiar.

Thanks for your instruction.Yes this is a fresh installation. I recently installed Anaconda on my system and i had anaconda before . I set up Windows and installed a fresh copy of Anaconda. However when I try to open an .ipynb file from Anaconda via jupyter, it doesn’t open or nothing happens, but the Python notebook (via python -m notebook) works fine.

Sorry. I should have better phrased the original question ‘clean’ or ‘pristine’, and maybe not ‘fresh’. (I meant fresh as in the machine was new and hadn’t been around a while.)
You had Anaconda before? But never on this machine?

You shouldn’t be running it that way though. If you installed with Anaconda you should either be using the Anaconda Navigator or the Anaconda prompt to run Jupyter.
Did you try those other ways to open up the Jupyter Notebook application? Hopefully if you do, then you’ll be able to open a notebook from Jupyter’s file browser page.

I had Anaconda installed on my PC previously, but after setting up Windows again, I encountered issues when trying to use Anaconda. Eventually, I decided to downgrade the Anaconda version, and now it’s working fine. Thanks for your help
