Issues with trame

[bjlittle]

So I've just created a new working environment in a new workspace, and pv.set_jupyter_backend("trame") totally does not work.

No matter if I reinstall or update ipywidgets, trame, and vtk I get the following error:

What do I do?

📢 Nice one! Your first issue! Thanks for telling us how to improve geovista 📢

[bjlittle]

@yutik-nn I've created a dedicated issue from your comment, hope you don't mind?

[bjlittle]

@yutik-nn Good to hear from you again 😃

Okay, so can you give me a little more detail, and hopefully we can resolve this for you.

Would it be possible to tell me how you're creating your environment?

Also, could you run this on your command line scooby --report geovista (within your active development environment) and paste the output in this issue, thanks.

Aloha @bjlittle !!! Getting back into it with some new data as well. So some other things stopped working and my other environment was old and overflooded so I needed a clean slate. This new one is micromamba, and I installed all packages for geovista (like trame, vtk, ipywidgets) with conda forge. Unfortunately I deleted my old environment where geovista/trame worked last so I can't test that. scooby --report geovista gives the following: Python 3.10.13 | packaged by conda-forge | (main, Dec 23 2023, 15:35:25) [Clang 16.0.6 ] cartopy : 0.22.0 click : 8.1.7 click-default-group : 1.2.4 cmocean : 3.1.3 colorcet : 3.0.1 geovista : 0.4.1 matplotlib : 3.8.3 netcdf4 : 1.6.5 numpy : 1.26.4 platformdirs : 4.2.0 pooch : 1.8.1 pykdtree : 1.3.11 pyproj : 3.6.1 pyvista : 0.43.3 scooby : 0.9.2 vtk : 9.3.0 IPython : 8.22.1 PyQt5 : 5.15.9 imageio : 2.34.0 jupyter_server_proxy : 4.1.0 jupyterlab : 4.1.2 nest_asyncio : 1.6.0 pandas : 2.1.4 scipy : 1.12.0 trame : 3.5.2 trame_client : 2.16.2 trame_server : 2.17.2 tqdm : 4.66.2

Thank you!!!

@bjlittle Does anything look suspicious?

[bjlittle]

Apologies @yutik-nn, I'll look into this for you now :+1:

[bjlittle]

... okay, I can confirm that I can certainly replicate this issue on my side.

Clearly something has changed in the ecosystem recently :thinking:

Aloha @yutik-nn 🏄

Okay, cracked it ... sorry for the delay.

It took me a wee bit of time to figure this one out (also, I'm spinning too many plates atm, soz)

Create a conda YAML spec file, say called env.yml, with at least the following:

name: aloha

channels:
  - conda-forge

dependencies:
  - geovista
  - ipywidgets <9.0.0
  - jupyterlab <5.0.0
  - trame >=2.5.2
  - trame-client >=2.12.7
  - trame-server >=2.11.7
  - trame-vtk >=2.5.8
  - trame-vuetify >=2.3.1

Now create your conda environment with the YAML file i.e., if you're using micromamba, then I think it's just simply:

micromamba create -f env.yml

Then activate your aloha environment and start jupyter lab.

Out the box, execute the following in a jupyter lab cell:

import pyvista as pv
pv.Cube().plot()

This should just-work™️, hopefully 🤞

Please let me know how it goes.

@yutik-nn Does this fix your issue?

Keen to make sure you're unblocked 👍

[yutik-nn]

@bjlittle Thank you Bill! It did fix the issue! Now I will need to install other needed packages on top of the foundation you outlined above, and hope nothing breaks :) 🙏🏼🙏🏼🙏🏼

[bjlittle]

@yutik-nn That's awesome news!

I'd recommend creating your environment from scratch with your additional packages in the YAML file, if possible.

Now that you have a working YAML file you can easily delete and recreate the environment as you choose.

Feel free to close this issue, or leave it open if you need more assistance - always glad to help 👍
