Notebooks not showing

[schmoelder]

Description of your problem

I was very happy to read that a new version of spyder-notebooks was released and I immediately wanted to try it out. However, I could not get it to run.

What steps will reproduce the problem?

1. Install Spyder with conda install spyder -c conda-forge
2. Install spyder-notebook with conda install spyder-notebook -c conda-forge
3. Open Spyder, Go to Notebooks Tab.
4. Nothing happens.

What is the expected output? What do you see instead?

I would expect the notebooks to show. However, I get a "blank" page (see screenshot below).

Please provide any additional information below (stack trace, screenshots, a gif, etc)

When I click on Open a new Notebook, a new tab appears which is also empty. If I try to open an existing notebook, nothing happens.

I don't know if it helps but if I run import spyder_notebook, I get the following error:

Qt WebEngine seems to be initialized from a plugin. Please set Qt::AA_ShareOpenGLContexts using QCoreApplication::setAttribute before constructing QGuiApplication.

Hey @schmoelder, thanks for reporting. A couple of comments:

• Please uninstall this plugin spyder_okvim.spyder.plugin and try again. Perhaps there's a conflict between the two.

• Please go to this entry in the File menu

  

  and select Verbose:

  

  After Spyder restarts, go to the Tools > Debug logs menu

  

  open spyder-debug.log and upload it here.

[schmoelder]

Hey @ccordoba12, thanks so much for investigating this.

Please uninstall this plugin spyder_okvim.spyder.plugin and try again. Perhaps there's a conflict between the two.

I did, unfortunately, that didn't help.

open spyder-debug.log and upload it here.

Here you go: https://gist.github.com/schmoelder/bcfa4366fd68493573cee9eb9826c80e

If there is anything else I can do, please let me know! :)

[jitseniesen]

I don't see anything wrong in the logs. The notebook server is started as it should. Here are some more things you can try:

1. Go to the options menu of the Notebook pane (this is the button with three horizontal lines in the upper right corner) and click on "Server info". Look for error messages. The message "No QCoreApplication instance found" at the top of the log is harmless.
2. According to the debug log, the notebook server is started with the command

   /home/jo/software/miniconda3/envs/chromapy/lib/python3.9/site-packages/spyder_notebook/server/main.py --no-browser --notebook-dir=/tmp/spyder-jo/notebooks --NotebookApp.password= KernelSpecManager.kernel_spec_class=spyder.plugins.ipythonconsole.utils.kernelspec.SpyderKernelSpec --dark

   Run this command from the command line inside the chromapy environment and look for errors. One of the messages should give you a URL; open that in a web browser and make sure that it works.

3. Install Spyder and the spyder-notebook plugin in a fresh environment.

[dererumenergetica]

Hi, just did a clean installation of

• Anaconda-Navigator 2.3.2
• launched and updated Spyder 5.3.3
• in terminal: conda install spyder-notebook -c conda-forge
• open Ananconda-Navigator - Environments and search for "Spyder"
• update all dependencies of spyder-notebook and ensure it's marked running
• restart Spyder should work now.

[schmoelder]

Install Spyder and the spyder-notebook plugin in a fresh environment.

I created a clean (spyder) environment, the issue still persists.

Go to the options menu of the Notebook pane (this is the button with three horizontal lines in the upper right corner) and click on "Server info". Look for error messages. The message "No QCoreApplication instance found" at the top of the log is harmless.

No Errors here. This is the entire output:

No QCoreApplication instance found. Application patches not applied. You have to call load_stylesheet function after instantiation of QApplication to take effect.

Unfortunately, it's in German. I could try to change the system language if that helps.

[StevenChicken]

Thanks @dererumenergetica ,

following your procedure and properly updating the dependencies with

conda update anaconda
conda update spyder

in the terminal,

eventually worked for me!

[equaeghe]

I have seemingly the same issue. Namely, I get the notebook tab, but no notebook interface is visible there: From the verbose logs, I found the command that is (supposed to be?) run:

python /usr/lib/python3.10/site-packages/spyder_notebook/server/main.py --no-browser --notebook-dir=/tmp/spyder-equaeghe/notebooks --NotebookApp.password= --KernelSpecManager.kernel_spec_class=spyder.plugins.ipythonconsole.utils.kernelspec.SpyderKernelSpec

(I first did it without the python in front, but the file is not executable.) Running this file results in

No QCoreApplication instance found. Application patches not applied. You have to call load_stylesheet function after instantiation of QApplication to take effect.

What steps can I take to try and fix this issue?

[ccordoba12]

@equaeghe, I think this problem could be due to permission errors caused because you installed Spyder and Spyder-notebook system-wide.

So, please create an isolated virtualenv in your home directory and install Spyder-notebook there. Perhaps that fixes the issue for you.

I've tried to do this on Windows 11, and still no effect. I keep receiving a timeout error when I start spyder or try to open a notebook. Spyder, spyder-nodetbook, and jupyterlab are installed in the same venv. Python 3.11.

python -m venv spyder-ide
cd spyder-ide
Scripts\Activate.ps1
python -m pip install -U pip
pip install wheel
pip install spyder spyder-notebook

Then I get the following server info:

[schmoelder]

I also still have this issue, now on spyder 5.4.2

I do get some new output in the console, however. Don't know if it's related but maybe it helps:

/home/jo/software/miniconda3/envs/dev/lib/python3.10/site-packages/jupyter_client/threaded.py:73: RuntimeWarning: ZMQStream only supports the base zmq.Socket class.

                Use zmq.Socket(shadow=other_socket)

                no matter what other kind of socket your Context creates.

  self.stream = zmqstream.ZMQStream(self.socket, self.ioloop)

[ccordoba12]

@schmoelder, that warning is unrelated to this problem. On Linux it could be related to issue https://github.com/spyder-ide/spyder/issues/20358.

So, I'd like to ask you: is the Help pane working for you as expected?

[64kbyte]

I ran into the same two related issues:

1. Notebook showing up blank
2. Help pane showing up blank

I started with a Miniconda 3.10 environment. Followed directions to install spyder like this: conda create -c conda-forge -n spyder-env spyder numpy scipy pandas matplotlib sympy cython opencv spyder-notebook

The above appears to require an update of python to 3.11. I think this is what's causing the issues.

I setup the environment again. This time, without pointing to conda-forge: conda create -n spyder-env spyder numpy scipy pandas matplotlib sympy cython opencv

Looks like python 3.10.9 remains. And spyder is the older version 5.3.3. And help pane works.

Then installed the notebook plugin from conda-forge: conda install spyder-notebook -c conda-forge

Appears to work!

Now if I could only figure out how to get the debugger working in notebook... (maybe it's not supported yet)?

[vadim-zyamalov]

So, I'd like to ask you: is the Help pane working for you as expected?

Well, sort of. When I press CTRL + I in front of the object the help topic appears in the Help pane. But the Object search line doesn't work, it ignores any input I provide.

It takes place either with and without spyder-notebook and its depndecies installed.

[vadim-zyamalov]

UPD: tried on MacOS Monterrey in freshly created venv (Python 3.10.6, installed by Homebrew).

I've installed spyder and spyder-notebook via pip into the venv. Everything works as expected, both notepad and help pane.

In Windows 11 under venv help and notebook don't work. If installed system-wide help pane and notebooks work as expected.

[ccordoba12]

@64kbyte, you said:

Now if I could only figure out how to get the debugger working in notebook... (maybe it's not supported yet)?

That use case is still not supported but we'll try to in the future.

Also, what's your operating system?

[ccordoba12]

@d9d6ka, you said

In Windows 11 under venv help and notebook don't work. If installed system-wide help pane and notebooks work as expected.

That's very strange. What's your Python version?

Also, @dalthviz, could you check if Spyder-notebook is working for you if installed in a conda env on Windows?

[vadim-zyamalov]

@d9d6ka, you said

In Windows 11 under venv help and notebook don't work. If installed system-wide help pane and notebooks work as expected.

That's very strange. What's your Python version?

Well, I don't know, what happened, but help pane started working...

On my Windows machine Python 3.11.0 is installed. System-wide everything works. In venv notebook throws a timeout error.

I'll use a system-wide installed Spyder for now. Anyway thanks for this add-on, hope the source of the problem will be found.

[64kbyte]

Also, what's your operating system?

I'm on Ubuntu 22.04.

I dug a little deeper and played around with conda package versions. Looks the culprit may be in the interactions with the fontconfig package. A default install from the conda-forge channel will bring in fontconfig=2.14.2. I decided to try one version prior.

I made a fresh environment with:

conda create -c conda-forge -n pydev fontconfig=2.14.1 spyder spyder-notebook numpy scipy pandas matplotlib sympy cython opencv

Both help and notebook show up and are functional with Python 3.11 and spyder 5.4.2 and spyder-notebook 0.4.0.

[schmoelder]

Sorry, was afk yesterday...

So, I'd like to ask you: is the Help pane working for you as expected?

You're right, it's actually not working. Since I don't use it much, I had not noticed that.

Both help and notebook show up and are functional with Python 3.11 and spyder 5.4.2 and spyder-notebook 0.4.0.

I'm still on Python 3.10 but using spyder 5.4.2 and spyder-notebook 0.4.0 with fontconfig=2.14.1 (and 2.14.2 for that matter) did not solve the issue for me.

[dalthviz]

Also, @dalthviz, could you check if Spyder-notebook is working for you if installed in a conda env on Windows?

Tried creating a conda env (conda create -n spyder-notebook -c conda-forge python=3.10 spyder spyder-notebook) but seems like is working for me. The env spec:

Also, seems like the Help pane is not working too, right? Maybe then the issue could be related with QWebEngine process not being able to launch from that specific non system-wide venv? Also, where is located the venv where things are not working? If it is located in a network drive maybe the issue could be related to https://bugreports.qt.io/browse/QTBUG-84632

Hey guys, I think this will be solved when we release Spyder 5.4.3 next month thanks to the fix in https://github.com/spyder-ide/spyder/pull/20482. That should solve the problems @schmoelder is having on Linux and @d9d6ka on Windows.

We'll let you know when that release is out so you can try Spyder-notebook again afterwards.
