Interesting. Feels like we're getting closer!

The kitty graphics protocol allows you to do more complex things with images then sixel graphics, such as hide & show, duplicate, and move images. Currently I'm not making full use of it's capabilities - I'm just clearing all images from a notebook and re-drawing them every time the display is drawn.

I'm already aware of some issues with with the way I implemented this (one is that images are cleared per notebook, which means that if you have multiple notebooks, only the images from one notebook will be displayed). I suspect the problem you are having may be related.

Rewriting the euporie's kitty graphics code so images are shown, hidden, and moved without re-drawing them is on my to-do list.

The "colinear!" text you are seeing is OS-level standard error output from the kernel (reportlab prints directly to stderr in it's c-extensions - see here).

The same thing happens with JupyterLab - output is printed to the terminal where the kernel was started rather than being displayed in the notebook:

There is an old IPython issue about this I remember from years ago: ipython/ipython#1230

The issue mentions a nice IPython extension wurlitzer you can use to work around this:

For what it's worth: just tried to run using a direct install from master (0.1.11), didn't work either

from euporie.

This doesn't seem to be matplotlib related, the following causes the same error (works well in ipython)

from prompt_toolkit import print_formatted_text, HTML

print_formatted_text(HTML('<b>This is bold</b>'))

from euporie.

Hi,

I'm a bit surprised you were still experiencing this with 0.1.11, as after 76d7831 TextArea is no longer used to display any outputs. Do you mind checking again you were actually using 0.1.11 or newer?

I've been working on fixing the display of ansi output containing carriage returns (which includes print_formatted_text output). A tentative fix for this is in 1d4884e.

The two code snippets you posted look currently give the following output with master in kitty terminal:

from euporie.

Yeah I mean I showed you the pip install output directly copy pasted so unless something with poetry is wonky it should've been 0.1.11.

I just tried to reinstall it (I have no experience with poetry, just doing poetry install), however I'm running into this:

python-poetry/poetry#3628

I tried uninstalling poetry, and deleting the git project and reinstalling everything twice but to no avail so unfortunately I can help debug because I can't install euporie anymore and pip is still at 0.1.9.

from euporie.

Forgive me if I'm telling you what you already know.

It appears you might still have 0.1.9 installed on your main python distribution. To upgrade euporie to the latest version, you can run:

pip install --upgrade euporie

This should update euporie to 0.1.11 or later.

If you want to run euporie from master, you'll need to run something like:

git clone https://github.com/joouha/euporie.git
cd euporie
poetry install
poetry run euporie

Running poetry install from the cloned repo makes poetry install euporie as a development install (along with its dependencies) into a virtual environment, which is isolated from your system python installation. Running euporie without activating the virtual environment first will still run the version installed installed on your system distribution with pip.

You can run euporie from this virtual environment using poetry run euporie, or you can launch a shell with the virtual environment activated using poetry shell, and run euporie from there.

thanks a ton for the help with debugging here! We're making progress:
so installing the new 0.1.11 from pip got rid of the error messages (I did however make sure that there is no 0.1.9 pip install in any of my envs before, however at time of my previous writing pip installs still installed 0.1.9 even for fresh installs, so now it's pulling correctly)

Now I'm not getting any errors, but also no outputs for the plotting

Thanks this is very helpful! However, unfortunately, like the issue I've linked, I can't run any poetry commands right now, even after wiping it from my system/fresh install. The linked issue mentiones potential to delete the cache folder fixing it, however, this cache isn't created on my machine (no ~/.cache/pypoetry or similar). There is osx specific caches in ~/Library/caches/pypoetry and I did try deleting that but to no avail). So unfortunately any poetry command (poetry show, poetry install right now results in

❯ poetry install

If you install timg do you get ansi images when you try plotting?

You can install it as an optional dependency of euporie with:

pip install --upgrade euporie[images-timg]

Have you tried upgrading poetry? You appear to be running 1.10.0b or similar.

from euporie.

poetry is/was on 1.16 according to it's CLI. timg doesn't seem to help

from euporie.

I solved the poetry issue (was a package installed somehow with invalid metadata file). However, on the master branch's version of 0.1.12 the display issues still persist

from euporie.

I'm a bit perplexed!

This could be a bug with kitty image rendering. I know the way I have implemented kitty image rendering needs work. What version of kitty are you using? (Unfortunately I do not have access to a Mac).

If you create a cell with an image output then scroll so the cell is partially off-screen, do you see the image rendered as text?

Are you able to get text-mode image output in another terminal?

from euporie.

Using kitty 0.19.3

both timg and the matplotlib kitty backend work well

Again thanks a lot for helping debugging this.

wrt to Mac: I know a lot of co's use https://www.macstadium.com/ for their CI to test things.

from euporie.

Just noticed something odd - if I open a notebook that contains images, the images are displayed correctly.

and indeed, when i scroll it half off the page, they become text like

from euporie.

Yes I had realized that this actually occurs in other frontends as well (which is why I had deleted the comment). Thanks a lot this is super helpful though

from euporie.

@joouha I think this isn't a png specific issue btw - also occurs for svg's - just no output created when printing them.

from euporie.

The reason this occurs with SVGs is because euporie converts them to PNG format to render them.

Could you try upgrading to 0.1.14 and printing a notebook with the --dump command line flag? I'd be interested to see if you get image output.

from euporie.

Unfortunately doesn't

from euporie.

Also just updated kitty to 0.20.3, didn't help either :/

from euporie.

FYI @joouha - i finally had time to dig deeper here and now see where the opening of another NB with image works vs local fails. Appears to have something todo with the kernel's response. Here is the msg returned when executing a command

You can see that

        elif msg_type in ("error", "display_data", "execute_result"):

are never hit so it'll never render.

I'm not too familiar w/ the jupyter message protocol but will debug further

from euporie.

Fixed it!

poetry made this extra difficult to debug as it had a lot of issues I never encountered with normal pip repos, ran into a lot of open issues on the repo, just my 2cents, you might want to consider to switch to pip (I appreciate the design decision of poetry and the problem it tries to solve, but in practice it didn't solve it for me while the conda/pip combo with pinned versions in requirements works good enough).

from euporie.

Awesome - I'm so pleased you fixed this!

What actually was the problem in the end?
