I had a Jupyter notebook running in my browser, and suddenly I was told that there was a problem with connection to the server. It seemed like Julia had crashed…
When I open notebooks after that, some cells don’t show in the browser, but are indicated by horizontal lines:
Apparently, the code is still there. When I open the notebook in an ASCII editor, I observe that code cells that still are visible, have the following structure:
"x0 = [28., 28., 28., 14.,18.,22.]\n",
"tspan = (0.0,583*60.)\n",
"execution_count": 12,), while cells that are hidden look like:
"# Model vs data\n",
"idx = 1:10:584\n",
- Is the problem that the execution count has been set to
- Can I manually change this to some number? Do the
execution_count number has to be an integer in sequence, starting from the top?
I’ll check. I did
Pkg.update(), but perhaps more is needed.
Yes, I used
jupyterlab(), and the the notebook opens without problem in
OK… I did:
leading to a question whether I want to install
jupyterlab. I answered “yes”.
The problem still persists.
sorry, I have no other ideas
OK – I removed everything relating to Julia, Conda, Matplotlib, Jupyter, etc., and upgraded to Julia v1.6.3 + reinstalled packages.
Now, it seems like I can open the notebook using
jupyterlab()… BUT after running for a while, I keep getting the following message:
I’m on Windows 11, and I have a feeling Microsoft updated Microsoft 365 on my computer yesterday, and possibly browser (chromium) Edge.
- Could a bug in the Julia - Edge interaction have been introduced? [I’ll try to use Firefox as browser – unfortunately, in Windows 11 it is more complicated to change browser…]
I have been experiencing the same issue for about 3 days. I noticed that whenever I do not accept updates and postpone them for a future time, Windows (10 in my case) generates troubles. After installing updates the issues disappear.
In addition to updating to Windows 11 + possibly an update in Edge/Windows 365 on my computers, I have also been asked to use
Conda to update
