A problem with headless JAVA install by default (with a solution)

[Maltiec]

ok, so I've come to this problem while installing py5 on Linux and in google colab, this command:

print('Java installed to', jdk.install('17'))

seems to install headless java by default, I've added parameter jre=True and it solved the problem:

print('Java installed to', jdk.install('17', jre=True))

Looks like installation instruction needs this update?

[Maltiec]

nope, in colab - still some problems.

I have added this text, let me know if it makes sense...

@Maltiec, I know @hx2A is pressed for time lately (and I should be doing something else entirely 🤣) but if you do interesting stuff with py5 on Colab, share it on a thread here on discussions!

Beware installing py5jupyter breaks Collab because it updates ipython and ikernel in incompatible ways.

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
google-colab 1.0.0 requires ipykernel==6.17.1, but you have ipykernel 6.29.5 which is incompatible.

yep, I already tried that thing, in fact that was my first step on this collab minefield )

Note that Jupyter Hub is also a OK choice for py5. There are free online Jupyter Hub servers you can use if you don't want to run the server yourself.

[villares]

Is mybinder.org based on Jupyter Hub tech? @hx2A, after the next py5 release you might want to have a look at that again maybe? (but it was a bit slow to boot, so maybe not)

[hx2A]

Yes, mybinder.org is Jupyter Hub. After the next release and after The Whitney show opens, the first order of business is to catch up on my sleep and build unit tests for py5. I'll revisit py5+Jupyter Hub eventually, but there are other things in front of that in the queue.
